[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] Re: Is recursion in XSL really this difficult?
 Ordinarily, I'm reluctant to answer posts from people who don't sign their name, since I like to have at least *some* clue of who they are. But since I tackled a problem somewhat like yours back when in a project I distributed, I thought I'd post it. Note that this recursive string-finding bit doesn't do a case-insensitive match, or make allowances for whitespace (which, judging from a cursory glance at your code, you apparently want). But it might give you a place to start. Import this stylesheet into yours: <xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"><!-- The 'segmentfunc' named template returns, for a given node,
a text string with all occurrences of a given substring
isolated by markup. The substring to be isolated must be
passed to the template as the 'find' parameter: its markup
is provided by another named template, 'displayfound' (to
be provided in the main stylesheet).Wendell Piez, Mulberry Technologies, December 1999. --> <xsl:template name="segmentfunc">
<xsl:param name="procstring">
<!-- the string to be processed. Trimmed recursively until
all occurrences have been isolated and passed to
'display'. -->
<xsl:value-of select="."/>
</xsl:param>
<xsl:choose>
<xsl:when test="$find and contains($procstring, $find)">
<xsl:value-of select="substring-before($procstring, $find)"/>
<xsl:call-template name="displayfound"/>
<xsl:call-template name="segmentfunc">
<xsl:with-param name="procstring"
select="substring-after($procstring, $find)"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$procstring"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template></xsl:stylesheet> -- and then, place a template such as this one in your main stylesheet (to provide your found string with markup in the output) -- <xsl:template name="displayfound">
<!-- Providing markup for the found string. -->
<xsl:param name="displaystring"/>
<b>
<xsl:value-of select="$find"/>
</b>
</xsl:template>(This one wraps your found string in a <b> element, assuming that string is identified in a global variable or parameter $find; do what you will.) I hope that helps. --Wendell
