You have already been told a possible solution for your problem. This solution: <xsl:variable name="status"> <xsl:for-each select="$node-set> <xsl:if test="condition"> <xsl:value-of select="true()"/> </xsl:if> </xsl:for-each> </xsl:variable> has some pitfalls: in the sample code Mr.Rajkumar provided, the test="$status" is always true, you need to test string($status). There may be better solutions, depending on what you actually want to do. If you want to test whether there are nodes fulfilling a certain condition within a given node set, you can try <xsl:if test="$node-set[condition]"> <!-- your code here --> </xsl:if> directly.
