RE: merging unknown nodes

["Kevin Jones" <kjouk@xxxxxxxxxxx>]

Jon,

This should do the trick,

<xsl:for-each select="/PRODUCTS/PRODUCT/OPTIONLIST">
	<xsl:if test="not (@name = preceding::OPTIONLIST/@name)">
		<xsl:variable name="name" select="@name"/>
		<OPTIONLIST name="{$name}">
			<xsl:copy-of select="/PRODUCTS/PRODUCT/OPTIONLIST/*[../@name=$name]"/>
		</OPTIONLIST>
	</xsl:if>
</xsl:for-each>

Kev.
