How to dynamically fetch value from url in XSLT - url

Question

I have a url of type C:/Documents and Settings/Saxon/output1/index.html?value=65abc
Now i need to fetch this part from url '65abc' in my xslt. I am getting this value from the previous page when click on a link.
Any idea of how to do it?

Use:
substring-after($pPath, '=')
where $pPath is a reference to the global external xsl:param that contains the value of the url-like) file path, passed from the invoker of the transformation.
In case that pPath contains more than one query-string parameter and you want to access the value of first one, then use:
substring-after(substring-before(substring-after($pPath, '?'), '&'), '=')
If you are using XSLT 2.0 (XPath 2.0), then you can access the value of the the query-string-parameter named $pQName using:
substring-after
(tokenize(substring-after($pPath, '?'), '&')
[starts-with(., concat($pQName, '='))],
'='
)
Here are complete code examples:
The simplest case:
. . .
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:param name="pPath" select=
"'C:/Documents and Settings/Saxon/output1/index.html?value=65abc'"/>
<xsl:template match="node()|#*">
<xsl:sequence select="substring-after($pPath, '=')"/>
</xsl:template>
</xsl:stylesheet>
when this is applied on any XML document (not used), the wanted result is produced:
65abc
.2. When this transformation is performed on any XML document (not used):
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:param name="pPath" select=
"'C:/Documents and Settings/Saxon/output1/index.html?value=65abc&x=1&y=2'"/>
<xsl:param name="pQName" select="'x'"/>
<xsl:template match="node()|#*">
<xsl:sequence select=
"substring-after
(tokenize(substring-after($pPath, '?'), '&')
[starts-with(., concat($pQName, '='))],
'='
)"/>
</xsl:template>
</xsl:stylesheet>
the wanted string (the value for the query-string parameter named x) is produced:
