I'm trying to get some matching using XMLTasks to replace some values in a xml file but it keeps failing due to no match. Using other tools it says that my xpath is correct but I can't figure out what's wrong.
Here the file I'm searching:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<project xmlns="http://www.netbeans.org/ns/project/1">
<type>org.netbeans.modules.apisupport.project</type>

<class-path-extension>

</class-path-extension>
<class-path-extension>

<binary-origin>../../Simple Marauroa Java/Card Game interface/dist/y.jar</binary-origin>
</class-path-extension>
</data>
</configuration>
</project>
And this is the path expression I'm using:
/project/configuration/data/class-path-extension[1]/runtime-relative-path/text()
Here are the relevant parts of the task I'm trying to run:
<target name="s" depends="-define-xmltasks">
<propertyselector property="subprojects" match="original.project.dir(.*)" select="\1"/>
<for list="${subprojects}" param="subproject">
<sequential>
<xmltask source="nbproject/project.xml" dest="nbproject/project.xml" failWithoutMatch="true">
<replace path="/project/configuration/data/class-path-extension[@{subproject}]/runtime-relative-path/text()"
withText="ext/extension/${extension-lib@{subproject}.dist.jar}"/>
<replace path="/project/configuration/data/class-path-extension[@{subproject}]/binary-origin/text()"
withText="${original.project.dir@{subproject}}/dist/${extension-lib@{subproject}.dist.jar}"/>
</xmltask>
</sequential>
</for>
</target>
@{subproject} resolves to a number and already tried changing it for a number but has the same effect. Any idea?
And this is the path expression I'm using:
/project/configuration/data/class-path-extension[1]/runtime-relative-path/text()
One way to deal with unprefixed names that are in a non-empty (default) namespace, is to specify the name as a predicate.
Here is an XPath expression written in this style that selects the wanted node(s):
/*[name()='project']
/*[name()='configuration']
/*[name()='data']
/*[name()='class-path-extension'][1]
/*[name()='runtime-relative-path']
/text()
XSLT - based verification:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="/">
<xsl:copy-of select=
"/*[name()='project']
/*[name()='configuration']
/*[name()='data']
/*[name()='class-path-extension'][1]
/*[name()='runtime-relative-path']
/text()
"/>
</xsl:template>
</xsl:stylesheet>
When this transformation is applied on the provided XML document:
<project xmlns="http://www.netbeans.org/ns/project/1">
<type>org.netbeans.modules.apisupport.project</type>
<configuration>
<data xmlns="http://www.netbeans.org/ns/nb-module-project/3">
<code-name-base>simple.server.extension.cardgame</code-name-base>
<suite-component/>
<module-dependencies>
<dependency>
<code-name-base>marauroa.lib</code-name-base>
<build-prerequisite/>
<compile-dependency/>
<run-dependency>
<release-version>3</release-version>
<specification-version>8</specification-version>
</run-dependency>
</dependency>

</run-dependency>
</dependency>

<class-path-extension>
<runtime-relative-path>ext/extension/x.jar</runtime-relative-path>
<binary-origin>../../Simple Marauroa Java/Card Game Extension/dist/x.jar</binary-origin>
</class-path-extension>
<class-path-extension>
<runtime-relative-path>ext/extension/y.jar</runtime-relative-path>
<binary-origin>../../Simple Marauroa Java/Card Game interface/dist/y.jar</binary-origin>
</class-path-extension>
</data>
</configuration>
</project>
the XPath expression is evaluated and the selected node is copied to the output:
ext/extension/x.jar
Note: For incremental building and verification of XPath expressions you can use a tool such as the XPath visualizer. This tool has helped many thousands of people learn XPath the fun way.
