Use FXSL.

You could use a functional composition (compose-flist) of:

strReverse, str-takeWhile, str-dropWhile, strReverse

or more simply only strReverse combined with substring-after and
substring-before:

testGetFileName.xsl:
-------------------
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 
  <xsl:import href="strReverse.xsl"/>
  
  <xsl:output method="text"/>
  
  <xsl:template match="/">
    <!-- 1. Reverse the string -->
    <xsl:variable name="vstrReversed">
	    <xsl:call-template name="strReverse">
	      <xsl:with-param name="pStr" select="string(/*)"/>
	    </xsl:call-template>
    </xsl:variable>

    <xsl:variable name="vstrRevFileName" 
                  select="substring-after
                              (
                               substring-before($vstrReversed, '/'),
                               '.'
                               )"/>
    
    <xsl:variable name="vPartialFileName">
      <xsl:call-template name="strReverse">
	      <xsl:with-param name="pStr" select="$vstrRevFileName"/>
      </xsl:call-template>
    </xsl:variable>
    
    <xsl:value-of select="concat($vPartialFileName, '_p.html')"/>
  </xsl:template>
</xsl:stylesheet>


When the above transformation is applied on the following source xml
document:

<text>file:/C:/Documents and
Settings/nshaw.HQIRMS/MyDocuments/spaceresearch/newxml/general_info/what.xml</text>


The result is:
what_p.html


Hope this helped.
