you are parsing the xml correctly, the trouble is that you are not
displaying it correctly.
>From your code:
<x:out select="$parsedxml//*"/>
This will show nothing, as the "String XPath value" of your whole xml is
empty
<c:out value="${parsedxml}"/>
This shows [#document: null], since you'r displaying an object of type
org.w3c.Document, whose toString() method returns : "[" + name-of-the-node +
": " + value-of-the-node + "]".
It's an xml-xpath problem what you are witnessing, not an jstl one.
Back in the "String XPath value" issue, the XPath specification says
that the value of transforming a node or a set of them into a String is the
concatenation of the values of the text or cdata nodes contained in the
subtree. A strange way of saying that it merely remove the tags (attributes
included)
If you use the following tag, you should see something:
--->><x:out select="$parsedxml/MenuConfig/Menus/Menu/@name"/><<---
That should output:
--->>UserMenu<<<---

Subject: Unable to parse XML input using x:parse
I am having a problem with the x:parse tag.
Im using the standard 1.05 apache jstl taglib in a struts 1.1 app on
Jboss3.2.3
No matter what I do the xml fails to parse and a null document is produced.
The xml exists as a string property on a bean.
the xml is as follows -
<?xml version="1.0" encoding="ISO-8859-1" ?>
<MenuConfig>
<Menus>
<Menu name="UserMenu" title="HOMEMENU" description="test"
mtype="">

description="test" mtype=""/>
</Menu>
</Menus>
</MenuConfig>
the page parsing it is -
<%@ taglib uri="/WEB-INF/c.tld" prefix="c" %>
<%@ taglib uri="/WEB-INF/x.tld" prefix="x" %>
<html>
<body>
<title> Test page </title>
<h1> Xml display - from loaded value</h1>
<c:out value="${MenuBuilderForm.userXmlMenu}" escapeXml="false"/>
<x:parse var="parsedxml" xml="${MenuBuilderForm.userXmlMenu}" />
<x:out select="$parsedxml//*"/>
<c:out value="${parsedxml}"/>
The output is -
Xml display - from loaded value
[#document: null]
But viewing the souce shows the c:out has written the xml to the source of
the page showing it is loaded on the bean and is in scope.
All the relevant jars are in /WEB-INF/lib and the tld's in /WEB-INF/ - have
also had the same issue with 1.04 and 1.02 taglib.
any ideas?
