Re: building a hierarchical classification out of flat

Hello,
you might try replacing the second key 'content' with a copy template:

<xsl:template match="unit">
	<xsl:copy>
		<xsl:copy-of select="@*"/>
		<xsl:apply-templates select="child::node()[1]" mode="copy"/>
		<xsl:apply-templates select="subunit"/>
	</xsl:copy>
</xsl:template>

<xsl:template match="subunit|sub-subunit|sub-sub-subunit">
	<xsl:copy>
		<title><xsl:value-of select="."/></title>
		<xsl:apply-templates select="following-sibling::node()[1]" mode="copy"/>
		<xsl:apply-templates select="key('ptr-down', generate-id(.))"/>
	</xsl:copy>
</xsl:template>

<xsl:template match="node()" mode="copy">
	<xsl:copy-of select="current()"/>
	<xsl:apply-templates select="following-sibling::node()[1]" mode="copy"/>
</xsl:template>

Hi,

I have been trying the code, and the output it's not that I expect
because the tag subunit is identet inside another subunit like this

</sub-sub-subunit>
</sub-subunit>
</sub-subunit>
</sub-subunit>
</sub-subunit>
</sub-subunit>
</sub-subunit>

And there are duplicated nodes

But the use of the key to mark set of block is very interesting.

Thank you.

Hi,

Now, I try it
Seems much easy with keys.Thank you.
