XPath Not() function always returning false AND context question.

[Sébastien Brodeur]

We are migrating from WebSphere 5 (and JSTL 1.0) to WebSphere 6 (JSTL 1.1).

We have some incompatibility issues.

When I try to use the XPath not() function to evaluate if a select statement
will return something, I always get false.

Example:

<?xml version="1.0" encoding="ISO-8859-1"?>
<books>

 <collection>
   <name>My collection</name>
 </collection>

 <book id="1">
   <author>Isaac Asimov</author>
   <title><![CDATA[La cité des robots]]></title>
   <year>1980</year>
 </book>
</books>

...
<x:when select="not($xml/books/book[id=1]">
...

Will return false EVEN if the id exist.


Also, when I uses <x:forEach>, I can't no longer access XML node outside the
scope of the select.  I have to use a 'weird' syntax to access those nodes.

Work in JSTL 1.0 and don't in JSTL 1.1

<x:forEach select="$xml//books/book" var="current_book">
 <x:out select="$xml//books/collection/name" />
</x:forEach>

I must uses instead

<x:forEach select="$xml//books/book" var="current_book">
 <x:out select="current_book/../collection/name" />
</x:forEach>
