When I use the latest xtag library with dom4j-full v1.1, it seems that the 
library does not function properly.  I find that code that used to work no 
longer does.  I am trying to select from my xml document the one topic 
specified from the query string, but my forEach statement is no longer finding 
anything and the select is staying at the root.  The code is:

<xtags:parse uri="help.xml"/>
<xtags:forEach select="/help/topic[topic-key=$topic][1]">
    <h2><xtags:valueOf select="//topic-key"/></h2>
    <xtags:forEach select="//description">
        <p><xtags:valueOf select="."/></p>
    </xtags:forEach>
</xtags:forEach>

And the xml file is:

<help>
     <topic>
        <topic-key>nohelp</topic-key>
        <topic-title>No Help Available</topic-title>
    </topic>
    <topic>
        <topic-key>managesite</topic-key>
        <topic-title>Manage Site</topic-title>
etc.

When this executes, it stays at the root, displaying the first topic only 
instead of the one I specified.

I uncompressed the examples and are running them unmodified on tomcat 3.3 with
jdk 1.3.01 and the only classes in my application classpath are dom4j-full.jar 
and xtags.jar.  Some of the examples work, for example, the simple rss example 
and the stock quote example.  However, the periodic_table and much_ado examples 
both give an exception, and periodic_table2 shows every element as having 112 
atoms.

Lastly, I tried the much_ado example again with the jar files that ship with the
xtags distribution and it doesn't work either, but the exception is different:
