Aron,
Thanks.
Of course the solution I posted doesn't work either, due to limitations of
XPath 1.0 and the fact that current() refers not to any node being
predicated, but to the current node (the node matched).
Quite an interesting problem, actually. It should be pretty straightforward
in XPath 2.0, but the only XSLT 1.0 solutions I've thought of are very ugly
and un-XSLTish. That may be unavoidable, again due to limitations in XPath
1.0 -- but before posting one of those I thought I'd give time to see if
others can work it out more elegantly....
Anyone?
Oh heck, here's an ugly solution:
<xsl:template match="root/*">
<xsl:variable name="include">
<xsl:call-template name="include"/>
</xsl:variable>
<xsl:if test="string($include)">
<xsl:copy-of select="."/>
</xsl:if>
</xsl:template>
<xsl:template name="include">
<xsl:for-each select="*">
<xsl:if test="following-sibling::*[name()=name(current())]">X</xsl:if>
</xsl:for-each>
</xsl:template>
It uses a template to fake a function, which returns a null value (which
fails the string() test) if there are no children that have following
siblings of the same name.
Cheers,
Wendell

The original problem asked (I think), given:
<root>
<sub_a>
<elem_1/>
<elem_2/>
<elem_3/>
</sub_a>
<sub_b>
<elem_1/>
<elem_2/>
<elem_2/>
<elem_2/>
<elem_3/>
</sub_b>
<sub_c>
<elem_1/>
<elem_2/>
<elem_3/>
</sub_c>
</root>
output:
<root>
<sub_b>
<elem_2/>
<elem_2/>
<elem_2/>
</sub_b>
</root>
Namely, output those sub_* which have more than 1 elem_* children named
the same; also output the elem_* children.
