Re: Adding Missing Elements

Given these possible variations and based on some processing elsewhere
in the document, I would like to make sure that <node> always has
<item>B</item> in its list...possibly adding <list> if it is not
present.

Can someone give me some suggestions on the best way to do this?

<xsl:stylesheet version="1.0" xmlns:var="myvar"
	xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
	
<xsl:output method="xml" indent="yes"/>

<var:root>
	<list>
		<item>B</item>
	</list>
</var:root>

<xsl:template match="node()|@*">
	<xsl:copy>
		<xsl:apply-templates select="node()|@*" />
	</xsl:copy>
</xsl:template>

<xsl:template match="node|list|item">
	<xsl:element name="{local-name()}">
		<xsl:apply-templates select="@*" />
		<xsl:apply-templates select="
			$var[current()/self::node][not(current()/list)]|
			$var[current()/self::list]/item[not(.=current()/item)]|
			node()" />
	</xsl:element>
</xsl:template>

regards,
