RE: [xsl] finding next element after

[Nathan Shaw <n8_shaw@xxxxxxxxx>]

Along the same lines, I am trying to prevent any
paragraph (p) element that only contains a Media
element from being wrapped in a p tag.

Here is what I have. Seems to work, but it is only
testing to see if the first elements are either

1) a Link element followed directly by a Media element
-OR-
2) a Media element


<xsl:template match="p">
<xsl:choose>
	<xsl:when test="((descendant::*[1])[self::Link] and
(descendant::*[2])[self::Media]) or
(descendant::*[1])[self::Media]"><xsl:apply-templates
/></xsl:when>
	<xsl:otherwise>
		<p><xsl:apply-templates /></p>
	</xsl:otherwise>
</xsl:choose>
</xsl:template>

Any cleaner way of doing this?

thanks,

--nate
