I have need to extract the "file name" from a string returned by
   unparsed-entity-uri. Obviously, the path is dependent on where the file sits
   so it can be of arbitrary length. The string I am dealing with is something
   like file:/C:/foo/bar/somefile.gif where I need the somefile.gif string. Is
   there a way to do this in XSL or with an extension? Any help would be
   greatly appreciated.


<xsl:call-template name="filename">
  <xsl:with-param name="x" select="$path"/>
</xsl:call-template>


$path is the expression with your path, and filename template looks
something  like this:



<xsl:template name="filename">
<xsl:param name="x"/>
<xsl:choose>
<xsl:when test="contains($x,'/')">
  <xsl:call-template name="filename">
    <xsl:with-param name="x" select="substring-after($x,'/')"/>
  </xsl:call-template>
</xsl:when>
<xsl:otherwise>
  <xsl:value-of select="$x"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
