Processing 2 times the same node without copying cont

Hello!

I have following problem: I need to add anchor support for quite big
stylesheets which produce HTML output. So I want to copy @id / add <a
name="{@id}"> to the result tree. But the problem is I can't do it in
this way:

<!-- HTML ANCHORS -->
<xsl:template match="*[@id]" priority="2">
	<a name="{@id}"/>
	
	<xsl:variable name="content">
		<xsl:copy>
			<xsl:apply-templates mode="anchor" select="@*|node()"/>
		</xsl:copy>
	</xsl:variable>
	
	<xsl:apply-templates select="xalan:nodeset($content)"/>
</xsl:template>

<xsl:template match="node()" mode="anchor">
	<xsl:copy-of select="."/>
</xsl:template>

<xsl:template match="@*" mode="anchor">
	<xsl:choose>
		<xsl:when test="name()='id'">	
		</xsl:when>
		<xsl:otherwise>
			<xsl:copy>
				<xsl:apply-templates select="."/>
			</xsl:copy>	
		</xsl:otherwise>
	</xsl:choose>
</xsl:template>

Because as far as I know xalan:nodeset changes input tree and that
stylesheet involve counting on preceding elements (to calculate how
many page breaks appeared). So I can't do that way :(.

Is there anyway to apply-templates on self node and ommiting some
attributes? It would be thing I am looking for... Thanks for help!
