Re: [xsl] another beginner question - strip directory info from variable

Dave --

I really like "tokenize( $filepath, '/')[last()]" for this. You may
well have tried that very thing, but the problem is you are handing
the tokenize() function a sequence of multiple filepaths, not just a
single filepath. To deal with this, you probably want to process the
sequence of filepaths such that you are only handling one at a time.
I don't know what is the *best* way to do this, but here are three
that all work.

'dir1/jpg003.jpg')"/>

the

    <xsl:variable name="jpgs_sans_dirs" select="for $j in $jpgs return 
tokenize($j,'/')[last()]"/>
    <!-- Now use xsl:for-each just to print them out nicely -->
    <xsl:for-each select="$jpgs_sans_dirs">

  </xsl:template>
  
</xsl:stylesheet>
