Re: JXTG Xpath returning NodeList

[Christopher Oliver]

This is due to the behavior of JXPath. If you want to process a node set 
you need forEach:

<?xml version="1.0" encoding="utf-8"?>
<page xmlns:jx="http://apache.org/cocoon/templates/jx/1.0";>
        <content>
        <jx:forEach select="#{document/root/path/fileset}"/>
       #{.}
       </jx:forEach>
        </content>
</page>
Your example is equivalent to:

 JXPathContext cx = JXPathContext.newContext(document);
 Node node = (Node)cx.getPointer("/root/path/fileset).getNode();
 ...
The forEach example is equivalent to:

 JXPathContext cx = JXPathContext.newContext(document);
 Iterator iter = cx.iteratePointers("/root/path/fileset);
 while (iter.hasNext()) {
    Pointer ptr = (Pointer)iter.next();
    Node node = (Node)ptr.getNode();
    ...
 }

Say you have this DOM you pass to a template:

<?xml version="1.0"?>
<root>
 <property file="user.properties" />
 <path id="all.cp">
   <pathelement location="${build.classes}" />
   <fileset dir="${cocoon.lib}">
     <include name="*.jar"/>
   </fileset>
   <fileset dir="${jetty.lib}">
     <include name="*.jar"/>
   </fileset>
   <fileset dir="${hsqldb.lib}">
     <include name="*.jar"/>
   </fileset>
   <fileset dir="${lib}">
     <include name="**/*.jar"/>
     <include name="**/*.zip"/>
   </fileset>
 </path>
</root>
template follows:
<?xml version="1.0" encoding="utf-8"?>
<page xmlns:jx="http://apache.org/cocoon/templates/jx/1.0";>
        <content>
                #{document/root/path/fileset}
        </content>
</page>
The result is :
<?xml version="1.0" encoding="ISO-8859-1"?><page
xmlns:jx="http://apache.org/cocoon/templates/jx/1.0";>
        <content>
                <fileset dir="${cocoon.lib}">
     <include name="*.jar"/>
   </fileset>
        </content>
</page>
Why doesn't it return all matching nodes and only the first one?

same goes with i.e. #{document/root/*}

A feature or a bug ?
