James Holmes commented on WW-2234:
----------------------------------
Did you ever find out a solution to this problem? Is there an issue with the
Struts 2 plugin or something in your code, etc.?
> XSLTResut.exposedValue transform failing on CDATA elements
> ----------------------------------------------------------
>
> Key: WW-2234
> URL: https://issues.apache.org/struts/browse/WW-2234
> Project: Struts 2
> Issue Type: Bug
> Affects Versions: 2.0.9
> Environment: Tomcat 6.0.14
> Struts 2.0.9
> JDK 1.5.0_11
> Xalan 2.7.0
> Reporter: Stewart Witchalls
> Priority: Minor
> Fix For: 2.1.3
>
>
> Xalan 2.7.0 (with bundled Xerces) installed into $JDK_HOME/jre/lib/endorsed
> and $TOMCAT_HOME/common/endorsed
> action config:
> <action name="ShowDataFormDemo" class="ShowDataFormDemo">
> <result type="xslt">
> <param name="location">/WEB-INF/xsl/CreateDataForm.xsl</param>
> <param name="exposedValue">presenterXml</param>
> </result>
> </action>
> ShowDataFormDemo.presenterXml code:
> public org.w3c.dom.Document getPresenterXml() throws Exception
> {
> final byte[] data = this.presenterXml.getBytes("UTF-8");
> final DocumentBuilderFactory factory =
> DocumentBuilderFactory.newInstance();
> final Document doc2 = factory.newDocumentBuilder().parse( new
> ByteArrayInputStream(data) );
> // debug to see if XPATH works inside server
> final XPathFactory fact = XPathFactory.newInstance();
> final XPath xpath = fact.newXPath();
> final XPathExpression xexpr = xpath.compile( "count(//items/*)" );
> System.out.println( xexpr.evaluate( doc2.getDocumentElement(),
> XPathConstants.NUMBER ) );
> return doc2;
> }
> XML:
> <data>
> <items>
> <heading inline="true">
> <text><![CDATA[Data form example]]></text></heading>
> <paragraph inline="true">
> <text><![CDATA[Some explanatory text.]]></text></paragraph>
> <subHeading inline="true">
> <text><![CDATA[Lists]]></text></subHeading>
> </items>
> </data>
> CreateDataForm.xsl fragment:
> vendor = <xsl:value-of select="system-property('xsl:vendor')"/>
> vendor-url = <xsl:value-of select="system-property('xsl:vendor-url')"/>
> xslt-version = <xsl:value-of select="system-property('xsl:version')"/>
> count(items) = <xsl:value-of select="count(//items/*)"/>
> XPath in code works and returns correct count (aka. 3).
> However, same xpath in CreateDataForm.xsl transform fails and only returns 1.
> Also, transform not able to obtain CDATA values (ie. displays nothing when
> "text" element selected).
> I've removed + added rows to the XML. The CreateDataForm.xsl transform always
> says count = "1". It looks like it cannot see past the first CDATA section.
> If I remove the CDATA sections (ie. encode the element data as XML encoded
> strings), transform xpath works??!!
> I've checked classpaths and can confirm that the endorsed Xalan libraries are
> being picked up.
> I've even run the transform inside the action itself. It worked as expected.
> I can work around this by removing the CDATA sections from the XML, but I've
> spent the last few days going mad. Just cannot see what's going wrong.
