xslt - extract leaf nodes

Question

I want to extract only the leaf nodes from an XML document (i.e., only elements that have no children). Has anyone written an xslt to do this?

Answer 1

Using axes in XPath:

<xsl:apply-templates select="//you-node-spec[not(child::*)]" />

Answer 2

SELECT="*[not(*)]"

Should give you anything without a child.
