Let's assume, we have some WSDL document to run the below stylesheet
(I tested with one of the examples available at,
http://www.w3.org/2001/03/14-annotated-WSDL-examples.html).

Below is a 1.0 stylesheet I could think of for this requirement:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                       xmlns:exslt="http://exslt.org/common"
                       version="1.0">

 <xsl:output method="text" />

 <xsl:template match="/*">
   <xsl:variable name="ns-map">
     <xsl:for-each select="namespace::*[not(name() = 'xml')]">
       <info>
         <prefix><xsl:value-of select="name()" /></prefix>
         <uri><xsl:value-of select="." /></uri>
       </info>
     </xsl:for-each>
   </xsl:variable>

   <!-- lookup example -->
   <xsl:variable name="key1" select="'es'" />
   <xsl:variable name="key2" select="'http://schemas.xmlsoap.org/wsdl/'" />

   <xsl:value-of select="exslt:node-set($ns-map)/info[prefix =
$key1]/uri" /><xsl:text>&#xa;</xsl:text>
   <xsl:value-of select="exslt:node-set($ns-map)/info[uri = $key2]/prefix" />
 </xsl:template>

</xsl:stylesheet>

I store the 'map' in a xsl:variable (a result tree fragment).

Please note, that this uses the node-set extension function to access
values from the 'map'.

This solution might look a bit complicated. But it might be necessary,
if you want the map to be stored somewhere, before accessing it.

Here is a simpler code, which directly accesses the properties of
namespace nodes:
(in this case the namespace nodes for the element could be considered
stored in a 'map')

<xsl:template match="/*">
  <xsl:value-of select="namespace::*[name() = 'es']"
/><xsl:text>&#xa;</xsl:text>
  <xsl:value-of select="name(namespace::*[. =
'http://schemas.xmlsoap.org/wsdl/'])" />
</xsl:template>

I have tested this with Xalan-J 2.7.1.

I hope that these examples would work with Xalan, bundled with JDK 5.
But I would recommend to use the latest Xalan version to have better
compliance and performance.
