Hi, Nadia,

Sure. You can do a test for it in either xsl:when or xsl:if. For example:

<xsl:if test="//@id='MyID'">
  <!-- Do something (perhaps apply certain templates) -->
</xsl:if>

Of course, if you can determine the exact path (not always possible 
because elements may be nested at different depths and so on), you can use 
the actual path instead of //.
