------------------------------------
Summary: xsl transformation having access to XML Schema
user-defined complex types
Key: XALANJ-2766
URL: https://issues.apache.org/jira/browse/XALANJ-2766
Project: XalanJ2
Issue Type: New Feature
Security Level: No security risk; visible to anyone (Ordinary problems in
Xalan projects. Anybody can view the issue.)
Components: Xalan-interpretive, XPath
Reporter: Mukul Gandhi
Assignee: Mukul Gandhi
I'm creating this jira issue to track implementation of this new feature within
Xalan-J's XSLT 3 dev branch.
The following shall be implemented within Xalan-J, as part of this jira issue.
XML input document:
<?xml version="1.0" encoding="UTF-8"?>
<info>
<address>
<fName>abc 1</fName>
<lName>mno 1</lName>
<addressLine1>address location details 1</addressLine1>
<city>hello 1</city>
<country>USA</country>
<state>state 1</state>
<zip>zip 1</zip>
</address>
<address>
<fName>abc 2</fName>
<lName>mno 2</lName>
<addressLine1>address location details 2</addressLine1>
<city>hello 2</city>
<country>USA</country>
<state>state 2</state>
<zip>zip 2</zip>
</address>
<address>
<fName>abc 3</fName>
<lName>mno 3</lName>
<addressLine1>address location details 2</addressLine1>
<city>hello 3</city>
<country>Singapore</country>
</address>
</info>
XSL transformation document:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:fn0="http://ns0";
exclude-result-prefixes="fn0"
version="3.0">
<xsl:output method="xml" indent="yes"/>
<xsl:import-schema schema-location="address.xsd"/>
<xsl:template match="/info">
<result>
<xsl:for-each select="address">
<address id="{'id_' || position()}">
<xsl:variable name="person1" as="element(*, Person)>
<xsl:copy-of select="fn0:getAddressInfo(. cast
as Address)"/>
</xsl:variable>
<xsl:copy-of select="$person1"/>
</address>
</xsl:for-each>
</result>
</xsl:template>
<xsl:function name="fn0:getAddressInfo" as="element(*, Person)">
<xsl:param name="addressElem" as="element(*, Address)"/>
<person>
<xsl:copy-of select="$addressElem/fName | $addressElem/mName |
$addressElem/lName"/>
</person>
</xsl:function>
</xsl:stylesheet>
The above mentioned XSL transformation document, refers to an XML Schema
document address.xsd (via XSL instruction xsl:import-schema) that provides
definitions of few XML Schema user-defined types as following:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";>
<xs:complexType name="Address">
<xs:sequence>
<xs:element name="fName" type="xs:string"/>
<xs:element name="mName" type="xs:string" minOccurs="0"/>
<xs:element name="lName" type="xs:string"/>
<xs:element name="addressLine1" type="xs:string"/>
<xs:element name="addressLine2" type="xs:string"
minOccurs="0"/>
<xs:element name="city" type="xs:string" minOccurs="0"/>
<xs:element name="country" type="xs:string"/>
<xs:element name="state" type="xs:string" minOccurs="0"/>
<xs:element name="zip" type="xs:string" minOccurs="0"/>
</xs:sequence>
</xs:complexType>
<xs:complexType name="Person">
<xs:sequence>
<xs:element name="fName" type="xs:string"/>
<xs:element name="mName" type="xs:string" minOccurs="0"/>
<xs:element name="lName" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:schema>
As specified above within this jira issue, when an XML input document shall be
transformed by an XSL transformation a normal transformation output shall be
produced, but XSL transformation shall ensure type checking with schema types
of the XML input nodes. The XSL transformation shall fail with type check
errors, if XML input nodes shall not conform with the specified schema types.
