[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] Re: Preserve ancestors/discard children
 Can you solve it with something like this approach:
<?xml version='1.0'?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="*|@*|text()">
<xsl:if test="./ul/li[not(@class='L')] or not(name()='ul')">
<xsl:copy>
<xsl:apply-templates select="*|@*|text()"/>
</xsl:copy>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
? I.e., perform an identity transform, but look ahead at UL's to see
if they have an LI with a CLASS attribute that is not 'L'. If they
meet that criterion, or the current node is not a UL, go ahead and
process it.
My sense is that what you are missing is what is normally the easiest
way to go about things in XSL, which is not to try to control
everything,
but instead just to sit back and let the template-evaluation sequence
over the tree do the work for you.
