Break Point in XML document: XPATH??

Hi all,
  I had earlier emailed regarding a break point in the an xml document. I 
need to transform the following document into another Xml document such that 
any tag below "break" should not be displayed.
 The XSLT transformation is such that I am having to do this from the
<xsl:template match= "elem1"> block. So my context or current node is 
<elem1>. How do I do it from here. I am having difficulty in writing the 
proper XPath exressions for this. Any help is greatly appreciated.
Thanks
Chandra

        <elem1>

             data2
          </selem2>
