Hi Mukul,
Your solution worked very nicely and has the added advantage that one
can create a single map and easily lookup map bi-directionally .
Thank you for your kind help.

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 =
$key1]/uri" /><xsl:text>
</xsl:text>
<xsl:value-of select="exslt:node-set($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>
</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.

Does xalan in JDK 5 support XSLT 2.0? I do not believe so. For this
reason I would like an XSLT 1.0 based solution.

Probably based on xslt:key ( <http://www.w3schools.com/xsl/el_key.asp>).

No I am looking for an in-memory solution that will be used within the
same stylesheet.

No the maps have to be internal to style sheet. An examples is shown
here under lookup table 1.6:

Hopefully my needs are clearer now?
