What's new in XSD 1.1

The XSD 1.1 standard builds on the XSD 1.0 adding a number of features that were conspicuous by their absence. Solving many of the problems that keep coming up in forums and discussion groups, it also remains compatible with the previous standard, meaning no need to upgrade existing schemas.Liquid Studio 2017 support XSD 1.1 as part of the graphical XML Schema editor.Summary of what’s new in XSD 1.1xs:alternative – provides value driven typing, if X=true then the element is of type Y xs:assert element – allows cross field validation via XPath predicate expressions. xs:assertion facet – allows value level validation via XPath predicate expressions. xs:openContent – enables extensibility by allowing additional elements throughout an element defaultAttributeGroup – add a group of attributes to every element defaultOpenContent – make every element extensible xCompatibility – using XSD 1.0 schemas with an XSD 1.1 validatorThe XSD 1.1 validator is compatible with the XSD 1.0 standard meaning you can pass your XSD 1.0 schemas using a XSD 1.1 validator and not notice any difference in the result.xs:alternativeProvides a mechanism for refining the type of an element based on an XPath expression. In XSD 1.0 this had to be been done explicitly using the xsi:type attribute in the XML document, but now it can be done implicitly via the schema.It sounds more complex than it is, an example will make it clearer.xs:alternative Sample<?xml version="1.0" encoding="utf-8" ?><!--Created with Liquid Studio 2017 (><xs:schema elementFormDefault="qualified" xmlns:xs=""> <xs:element name="Example"> <xs:complexType> <xs:sequence> <xs:element name="Address" type="AddressType" maxOccurs="unbounded"> <xs:alternative test="@country = 'UK'" type="UKAddressType" /> <xs:alternative test="@country = 'US'" type="USAddressType" /> </xs:element> </xs:sequence> </xs:complexType> </xs:element> <xs:complexType name="AddressType"> <xs:sequence> <xs:element name="Line1" type="xs:string" /> <xs:element name="Line2" type="xs:string" /> </xs:sequence> <xs:attribute name="country"> <xs:simpleType> <xs:restriction base="xs:string"> <xs:enumeration value="UK" /> <xs:enumeration value="US" /> </xs:restriction> </xs:simpleType> </xs:attribute> </xs:complexType> <xs:complexType name="UKAddressType"> <xs:complexContent> <xs:extension base="AddressType"> <xs:sequence> <xs:element name="County" type="xs:string" /> <xs:element name="Postcode" type="xs:string" /> </xs:sequence> </xs:extension> </xs:complexContent> </xs:complexType> <xs:complexType name="USAddressType"> <xs:complexContent> <xs:extension base="AddressType"> <xs:sequence> <xs:element name="State" type="xs:string" /> <xs:element name="ZipCode" type="xs:string" /> </xs:sequence> </xs:extension> </xs:complexContent> </xs:complexType></xs:schema>When the following XML document is validated, the test in each xs:alternative is evaluated, and the first one to pass is used. The first Address element has a the country set to ‘UK’ this matches the test @country = ‘UK’ in the first xs:alternative, so the validation continues on using the type UKAddressType.The 3rd address has country = ‘UK’ so the UKAddressType is used, however its does not contain the correct child elements, so validation fails.<?xml version="1.0" encoding="utf-8"?><!-- Created with Liquid Studio 2017 ( --><Example xmlns:xsi="" xsi:noNamespaceSchemaLocation="AlternativeExample.xsd"> <Address country="UK"> <Line1>string</Line1> <Line2>string</Line2> <County>string</County> <Postcode>string</Postcode> </Address> <Address country="US"> <Line1>string</Line1> <Line2>string</Line2> <State>string</State> <ZipCode>string</ZipCode> </Address> <Address country="UK"> <Line1>string</Line1> <Line2>string</Line2> <State>INVALID</State> <ZipCode>INVALID</ZipCode> </Address></Example>Propertiestest : The XPath expression which must evaluate to true in order for this alternative definition to be used. It is important to note that the XPath expression is limited to selecting attributes only. i.e. you can only base the expression on attribute values, you can not use it to access child elements.xpathDefaultNamespace : The default namespace used within the expression. If not specified then it is the default namespace of the containing element in the schema.xs:assertThe new xs:assert provides a mechanism for cross field validation, this makes it possible to implement complex business rules in an XSD schema, previously this kind of validation could only be accomplished in a limited sense with keyref’s, or by other tools (i.e. schematron).Although this new feature is very powerful, compromises have had to be made between performance, ease of implementation and functionality. In order to simplify implementations, and limit resources use, the XPath expression can only access nodes within the element it is attached to. In the example below, as it is attached to the paragraph element it can only access nodes within the paragraph (table/title), it can NOT access the parent element Example. The xs:assert has a attribute called test, this contains an XPath expression which is evaluated, if it does not evaluate to true, a validation error is raised.An xs:assert can be added to the following XSD entitiesxs:alternative xs:complexType xs:element Propertiestest : The XPath expression which must evalute to true for validation to be successfull.xpathDefaultNamespace : The default namespace used within the expression. If not specified then it is the default namespace of the containing element in the schema.Example xs:assert schemaThe following schema describes an assert on the paragraph element. Its basically saying if you have a table element the element before it must be a title.<?xml version="1.0" encoding="utf-8" ?><!--Created with Liquid Studio 2017 (><xs:schema elementFormDefault="qualified" xmlns:xs=""> <xs:element name="Example"> <xs:complexType> <xs:sequence> <xs:element name="paragraph" type="paragraphType" maxOccurs="unbounded" /> </xs:sequence> </xs:complexType> </xs:element> <xs:complexType mixed="true" name="paragraphType"> <xs:sequence> <xs:element name="title" type="xs:string" minOccurs="0" /> <xs:element name="table" type="xs:string" minOccurs="0" /> </xs:sequence> <xs:assert test="if (table) then table/preceding-sibling::title else true()" /> </xs:complexType></xs:schema>Example xs:assert sample XML documentThe following sample XML shows 3 paragraphs the first 2 are valid, the last one has a table element, but the element before is not a title (their is no element before it), so validation fails.<?xml version="1.0" encoding="utf-8"?><!-- Created with Liquid Studio 2017 ( --><Example xmlns:xsi="" xsi:noNamespaceSchemaLocation="AssertSchema.xsd"> <paragraph> <title>VALID</title> <table>VALID</table> </paragraph> <paragraph> <title>VALID</title> </paragraph> <paragraph> <table>NOT OK - Missing title</table> </paragraph></Example>xs:assertion facetAssertions are a new type of facet that can be applied to xs:simpleTypes, they contain an XPath expression which must evaluate to true in order validate. They can only operate on the value of the type (they can’t access other nodes in the XML document).Propertiestest : The XPath expression which must evalute to true for validation to be successfull.xpathDefaultNamespace : The default namespace used within the expression. If not specified then it is the default namespace of the containing element in the schema.$value : Within the XPath ‘test’ expression the built in variable $value is defined which represents the value to be tested.Sample xs:assertionIn the sample bellow the xs:assertion ensures that only even values are allowed.<?xml version="1.0" encoding="utf-8" ?><!--Created with Liquid Studio 2017 (><xs:schema elementFormDefault="qualified" xmlns:xs=""> <xs:simpleType name="EvenNumbers"> <xs:restriction base="xs:int"> <xs:assertion test="$value mod 2 = 0" /> </xs:restriction> </xs:simpleType> <xs:element name="Numbers"> <xs:complexType> <xs:sequence> <xs:element name="Number" type="EvenNumbers" /> </xs:sequence> </xs:complexType> </xs:element></xs:schema>xs:openContentOpen Content allows you to design schemas that are extensible in a way that was simply not possible in XSD 1.0. It provides a mechanism that allows additional elements to be either interleaved with existing elements or placed at the end.xs:openContent SampleIt is not unusual to want to create a schema that contains a set of defined elements, but can also contain anything else. The consuming application would then processes what it understands and ignore anything else. This seemingly simple goal is very awkward to achieve in XSD 1.0, but with the introduction of open content its simple.<?xml version="1.0" encoding="utf-8" ?><!--Created with Liquid Studio 2017 (><xs:schema elementFormDefault="qualified" xmlns:xs=""> <xs:element name="Book"> <xs:complexType> <xs:openContent mode="interleave"> <xs:any namespace="##any" processContents="lax" /> </xs:openContent> <xs:sequence> <xs:element name="Title" type="xs:string" /> <xs:element name="Author" type="xs:string" /> <xs:element name="Date" type="xs:gYear" /> <xs:element name="ISBN" type="xs:string" /> <xs:element name="Publisher" type="xs:string" /> </xs:sequence> </xs:complexType> </xs:element></xs:schema>The resulting XML document now allows the inclusion of any elements before, between and after the ones defined in the XSD. In this example the element ‘NewElement’ is added in the middle. <?xml version="1.0" encoding="utf-8"?><!-- Created with Liquid Studio 2017 ( --><Book xmlns:xsi="" xsi:noNamespaceSchemaLocation="OpenContentExample.xsd"> <Title>string</Title> <Author>string</Author> <NewElement/> <Date>2016</Date> <ISBN>string</ISBN> <Publisher>string</Publisher></Book>The mode Attributenone : Stops any open content rules being applied to this element (only relivant if a defaultOpenContent element has been applied to the whole schema).Interleave : Allows additional elements to be placed before, between and after the elements defined in the schema.suffix : Allows additional elements to only be placed after the elements defined in the schema.The xs:openContent element also requires a child xs:any which defines the type of elements that can be added (more about the changes to xs:any later).defaultAttributeGroupThis is a new attribute that can be attached to the xs:schema. When set it references an xs:attributeGroup which will be added to all the elements defined in this schema. It can be turned off on specific elements my setting the defaultAttributesApply=’false’ attribute on the given element.xs:defaultOpenContentThis is a root level open content element that is applied to all the elements defined within this schema. It can be turned off on specific elements by adding the an xs:openContent element with the attribute mode=’none’.Changes to xs:any The xs:any construct is a little more user freindly in XSD 1.1. its gained a coulple of atttributes to better control what is allowed, and it can be used a little more freely than before.notNamespace - this is a list of all the namesapces that are NOT permitted.notQName - this is a list of all the qualified element names that are NOT permitted. The use of xs:any is now a little less arduous, in XSD 1.0 the following is invalid. <xs:element name="Example"> <xs:complexType> <xs:sequence> <xs:any minOccurs="0" namespace="##any" /> <xs:element name="A" type="xs:string" minOccurs="0" /> </xs:sequence> </xs:complexType></xs:element>This is because the validator can not tell which rule should be applied to an element ‘A’ in the instance document. Both the any and the definition for ‘A’ would be acceptable. In order to prevent this ambiguity the XSD 1.0 rules make this construct invalid.However, in XSD 1.1 the construct is allowed as prioity is given to formally defined elements over those the would match an xs:any.SummaryThe enhancements made to the XSD standard seem fairly minor but now provide the ability to create truly extensible schemas, and support the implementation of complex business rules. For these reasons alone the XSD 1.1 standard is worth embracing, the other features are just a bonus.

Testing RESTful Web Services with Liquid Studio 2017

With the release of Liquid Studio 2017 we will see new functionality allowing you to test RESTful Web Service.Previously, the Web Service Test Client was limited to calling SOAP Web Services which could provide a WSDL (Web Service Definition Language) to describe the Web Service. This was fine for ASP.NET or WCF Web Services hosted on an IIS Web Server, but what about HTTP RESTful Web Services, maybe using Apache Web Server?Liquid Studio 2017 now supports using a WADL (Web Application Description Language) to describe the Web Service. If you don't have a WADL, you can easily create one using the new User Defined Web Service option.The User Defined Web Service option provides the ability to describe a Web Service Call by entering a Service Name, Base URI, Resource Path, Method (GET or POST) and Method Parameters. This is then saved as a WADL file for future use.This is just one of the many new features in Liquid Studio 2017. Please feel free to try out the BETA Test version.

Liquid XML 2015 BETA

The final BETA is now available for Liquid XML 2015.Download Liquid XML 2015 BETAThanks for all of the invaluable feedback we have received so far. We have tried to implement as many fixes and new functionality as possible to address the issues raised.What's New for 2015?Liquid XML 2015 extends and improves on the existing functionality by introducing other new tools and technologies that our users have requested in order to continue to make Liquid XML Studio the best value XML development environment available.NEW Data Mapper Code Generation and Database/Flat File SupportThe Graphical Data Mapper has been significantly upgraded to include new functionality for advanced Data Mapping.C# Data Mapping GeneratorC# source code can be generated to perform the data mapping as specified within the graphical editor.XSLT Data Mapping GeneratorXSLT source code can be generated to perform the data mapping as specified within the graphical editor.Database Source ComponentDatabase support has been added to allow you to read your source data from a database.Flat File Source ComponentFlat file support has been added to allow you to read your source data from a delimited or fixed field text file.Auto-Connect ToolNew auto-connect tool makes it easy to connect large structures of data, automatically reconciling similar names items.NEW JSON Text EditorText editor for JSON files includes color coding and code folding.XML to JSON Import and ExportImport XML as a JSON document and export it back to XML. In the same way as the existing Import JSON to XML function.NEW XML Data Binder Code Generation Support for WSDLThe Developer Edition XML Data Binding wizard now provides support for using the XSD embedded within WSDL files to generate the Data Binding library.Web Service InterfaceA new option has been added to generate a Web Service Interface in C# and VB .Net. This uses a Web Service WSDL to generate an interface which will bind directly to the web service using the Liquid Data Binding generated object library. The Wizard will also Auto-Filter the elements, only generating those required by the interface.XMLSchemaProvider AttributeA new option has been added to support the XmlSchemaProvider Attribute in C# and VB .Net. Previously if you wanted to use the Liquid Data Binding generated library in a Web Service, you had to add this support manually. The XSDs are also embedded in the generated library to support this feature, so no external web calls are required.New Fixes and ImprovementsMetro Light User InterfaceThe XML Studio now uses the Metro Light user interface style by default. The old interface can be selected form the Options dialog. Improved Memory Management and PerformanceFaster XML document load times and larger files supported in standard editor without the need for using the Large File Editor.Performance OptionsAdded options to stipulate when features will be disable as file sizes increase and at what point the Large File Editor is invoked over the standard editor.Synchronized XML ViewsClicking in the XML text view now synchronizes the XML Graphical view in the same way as the Graphical XSD editor.General ImprovementsAlong with the new features outlined above, existing features have also been enhanced and improved with functionality requested by our users.

CDATA processing in XML Data Binding

The default option when processing CDATA is to strip away the text ![CDATA[ ... ]] leaving just the contained value. This enables you to display and use  the values without the need for parsing. You can then manually add the ![CDATA[ ... ]] text back in when you set the text (i.e. if the user has updated the value).However, if you prefer to keep the CDATA tag in the element text, you can set StripCDATA = false in the XmlSerializationContext. But you would then need to strip the CDATA tag yourself before displaying the text to the end user.E.g.In C# you would set the following:LiquidTechnologies.Runtime.Net40.XmlSerializationContext.Default.StripCDATA = falseIn C++ you would set the following:LtXmlLib12::CXmlSerializationContext::GetDefaultContext().SetStripCDATA(false);Note: This behaviour is the same for simple elements defined as string in the XSD and for extended string elements which are accessed using the PrimitiveValue member in the generated source code.See AlsoCDATA processing in XML Data Binding

Error E2001 - The schema does not contain any 'elements' so will not generate any classes

If you run the Liquid XML Data Binder and get error E2001, it means you need to add at least 1 element in order to generate your C#, C++, Java, VB .Net or Visual Basic 6 classes.As explained in yesterdays blog Element vs complexType, you may only validate an xml document if your schema contains an element which describes each item (tag) used within the document.Wizard Error E2001MessageThe schema does not contain any 'elements' so will not generate any classes.ExplanationXml Schema elements can be considered as objects that have a type defined by the simple and complex types. So if no elements are specified in the schema, no classes will be generated as the optimiser will determine that none of the declared complexTypes will never be utilised.SolutionThe solution is to declare elements within the schema.E.g. The following Xml Schema (XSD) will not generate any classes as no elements are defined.<?xml version="1.0" encoding="utf-8"?>   <xs:schema xmlns:xs="" elementFormDefault="qualified" attributeFormDefault="unqualified">   <xs:complexType name="Item">     <xs:sequence>       <xs:element name="Description" type="xs:string"/>       <xs:element name="Quantity" type="xs:unsignedLong"/>     </xs:sequence>   </xs:complexType>   <xs:complexType name="QuotedItem">     <xs:sequence>       <xs:element name="Item" type="Item"/>       <xs:element name="PricePerItemInPence" type="xs:unsignedLong" minOccurs="0"/>       <xs:element name="CurrentAvalibility" type="xs:unsignedLong" minOccurs="0"/>     </xs:sequence>   </xs:complexType>However, by extending the schema to define the element QuoteRequest and its associated child elements, a full class hierarchy will be generated:  <xs:element name="QuoteRequest">      <xs:complexType>       <xs:sequence>         <xs:element name="CustomerID" type="xs:string"/>         <xs:element name="Item" type="Item" minOccurs="0" maxOccurs="unbounded"/>       </xs:sequence>     </xs:complexType>   </xs:element>  </xs:schema>See AlsoElements vs complexTypes

Element vs complexType

When to use ElementIf an instance document (xml document) requires an item named Address, then you MUST have an element defined within your xml schema named Address. Otherwise the xml document will never be valid against the schema.E.g. For the following XML Document item to be valid:<Address>…</Address>The XML Schema must define a corresponding element:<xsd:element name=”Address”>…</xsd:element>Furthermore, if other elements are allowed to act as substitute items, then the item must be declared as an element.When to use complexTypeAny time the above is not true you should consider using a complexType. Even when the above is true, you may still want to create a complexType to define the structure. This is especially true if the structure may be reused by multiple elements.E.g. If the Address structure may be used by HomeAddress and WorkAddress, you should define Address as a complexType:<xsd:complexType name=”AddressType”>…</xsd: complexType ><xsd:element name=” HomeAddress” type=”AddressType” /><xsd:element name=” WorkAddress” type=”AddressType” />Note 1: Whilst the complexType could be named “Address” is it good practice to make types distinct from elements, so here we use the name “AddressType”.Note 2: You could define AddressType as an element and use the “ref” attribute:<xsd:element name=”AddressType”>…</xsd: element > <xsd:element name=” HomeAddress” ref=”AddressType” />However, it is good practice to use complexType for the reusable building blocks that make up your document rules and use element for the actual tags that will be present within the document.Note 3: If you intend to use the “nillable” attribute, then you MUST use a complexType in the above example, as the ref and nillable attributes are mutually exclusive.

How to create XML Schema from XML Documents

Create XML Schema using XML documents directly from your XML Editor.Liquid XML Studio provides a great tool to enable you to infer XML Schema (XSD) from a set of XML Documents, via an easy to use Wizard user interface. This can save you hours of time when you need to define the rules for validating XML Documents which may have been provided by an external source.Along with been faster, using the tool is significantly more accurate than trying to manually work out what element and attribute values are allowed in the structure of the document.To use the wizard, follow these simple steps.Stage 1 - Select an XML Schema name and options:Stage 2 - Add sample XML Documents to help define the rules of the XML Schema:Stage 3 - Validate your XML Documents using the new XML Schema (XSD):Usage TipThe more sample XML Documents you add, the more accurate your XSD will be as the more rules for element structure and attribute values will be able to be determined by the tool.Download Liquid XML Studio free trial
