I need to be able to traverse down the tree and remove empty elements from any child node as well. Matt "Thomas B. Passin" To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx <tpassin@mitret cc: (bcc: Matthew J.

If so, you could test like this: <xsl:variable name='is-there-any-text'> <xsl:value-of select='.'> </xsl:variable> <xsl:if test='$is-there-any-text !=""'>....</xsl:if> Sorry all those quotes are hard to read, just get them to nest right.
