Even if you want to know whether there are 4 elements or not, you don't need to count them: <xsl:if test="BLOCK"> </xsl:if> tests whether a 4th BLOCK-element does exist. Your test as above has two little errors: <xsl:when test="count(BLOCK) > 0"> </xsl:when> There must not be an 'if' in the test. The element already has the name <xsl:if/> or <xsl:when/>. And - as David wrote - XML is case sensitive, so their is no XPATH function COUNT(), but count().
