XSL: Just the filename without the path

问题

I'm new in XSL programming and I guess it is a simple question: How can I get the filename without the path? At the moment my code looks like this and I get the whole path: Result.xml:

<?xml version="1.0" encoding="UTF-8" ?>

</xsl:stylesheet>

I only need to get it like Test.dotx or Test.xlsx. I tried sth with <xsl:value-of select="substring-after-last($url, '/')" disable-output-escaping="yes" /> but got an error.

What can I do? How can I solve my problem? Thans for your support. Kind regards, Matthias

If you're stuck with XSLT 1.0, you could use a recursive template like this:

Stylesheet

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
  <xsl:output method="text"/>

  <xsl:template name="substring-after-last">
    <xsl:param name="string"/>
    <xsl:param name="char"/>

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

  <xsl:template match="/">
    <xsl:call-template name="substring-after-last">
      <xsl:with-param name="string" select="'/var/log/tomcat'"/>
      <xsl:with-param name="char" select="'/'"/>
    </xsl:call-template>
  </xsl:template>

</xsl:stylesheet>

Output

tomcat

Note, though, that this template probably won't do what you want if the last character in your path is a /, because it'll always just return what's after the last $char. In other words, for /var/log/tomcat/ (as opposed to /var/log/tomcat, without the trailing forward slash), this template would return an empty string.

To use this in your own code, you could copy-paste the substring-after-last template above into your own code and instead of:

<xsl:attribute name="href">
  <xsl:value-of select="url" disable-output-escaping="yes" />
</xsl:attribute>

You could use:

<xsl:attribute name="href">
  <xsl:call-template name="substring-after-last">
    <xsl:with-param name="string" select="url"/>
    <xsl:with-param name="char" select="'/'"/>
  </xsl:call-template>
</xsl:attribute>

Here is a simple, non-recursive XSLT 1.0 solution:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output method="text"/>

 <xsl:variable name="vDoc" select="document('')"/>
 <xsl:variable name="vNodes" select="$vDoc//node()|$vDoc//@*|$vDoc//namespace::*"/>

 <xsl:template match="/*">
   <xsl:variable name="vLength" select="string-length()"/>
   <xsl:variable name="vCur" select="."/>
     <xsl:for-each select="$vNodes[not(position() > $vLength)]">
      <xsl:if test=
       "substring($vCur,$vLength - position()+1,1)='/'
       and not(contains(substring($vCur,$vLength - position()+2), '/'))
       ">
       <xsl:value-of select="substring($vCur,$vLength - position()+2)"/>
      </xsl:if>
     </xsl:for-each>
 </xsl:template>
</xsl:stylesheet>

When this transformation is applied on the following XML document:

<t>http://abc.com/seg1/seg2/seg3/seg4/seg5/filename.html</t>

the wanted, correct result is produced:

filename.html
