Can an XSLT parse a string of text?

fxsl, parsing, string, xslt

Solution

XPath contains the `substring-after` function which returns the string following the first occurrence of another string. This isn't enough by itself, but a template such as the following might do it:

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

The set of string functions available is not terribly extensive, but I've found that it is good enough for most applications that you'll need in XSLT.

Problem

This is my first time using XSLT. I'm trying to create a file that will convert an XML data file exported from a program I use to an HTML report. One of the element's value is path to an image file, but the path generated is an absolute path such as ``` C:\Documents and Settings\me\Desktop\xml export\cd000402.jpg ``` but I want a relative path to just the file name. Is there some way through the XLST file to parse out the file name?
