RE: [xsl] Delete XML Node

["KIENLE, STEVEN C [IT/0200]" <steven.c.kienle@xxxxxxxxxxxxx>]

Replace the for each with the Y[Z] with the following:

  <xsl:for-each select="Y[child::*]">
    <xsl:copy-of select="." />
  </xsl:for-each>

This will fire only for those Y which have children.  Then it makes a deep
copy of that node.

If you need this logic to apply you node more than Y, then you may want to
look at multiple templates instead of for-each elements.

Whoops, I shot myself in the foot here....

sorry folks I am new to XSL.... and pardon my ignorrance

To clarify things, I want an XSL which would output a <Y> if and only if it 
has a sub element in this case a <Z>. In the current example I have only one

sub element <Z> but there can be more than one sub-element of <Y>.

e.g.

<Y>
<Z></Z>
<D></D>
......
</Y>

I do not want <Y></Y> to appear in the output if all the sub-elements do not

map.

Thanks,
Deepak
