RE: Taking string out from the long string

Because substring-after extracts the substring after the *first* occurrence
the slash, you must use a recursive template, passing the path as a
parameter and extracting the substring-after each time until there are no
slashes left:

<!-- Match the img and call the named recursive template -->
<xsl:template match="img">
 <xsl:call-template name="getFilename">
   <xsl:with-param name="currentString" select="@src"/>
 </xsl:call-template>
</xsl:template>

<!-- Named recursive template -->
<xsl:template name="getFilename">
 <xsl:param name="currentString"/>
 <xsl:choose>
  <xsl:when test="contains($currentString,'/')">
   <!-- There are more folders to be removed, so recurse -->
   <xsl:call-template name="getFilename">
    <xsl:with-param name="$currentString"
select="substring-after($currentString,'/')">
   </xsl:call-template>
  </xsl:when>
  <xsl:otherwise>
   <!-- Now you just have the file name, so output replacing the extension
with wbmp -->
   <img src="{concat(substring-before($currentString,'.')),'.wbmp')}"/>
  </xsl:otherwise>
 </xsl:choose>
</xsl:template>

If there's a chance your filename may itself have more than one . in it,
you'll have to recurse on that string as well.

Hope this helps.
