Try using COUNT
you could do something like
<xsl:when test = "if COUNT(BLOCK) > 0>
........what u want to do </xsl:when>

lemme know if it worked...

Hello Anand,

you never need to count elements, if you only want to know, whether an element exists or not.

<xsl:if test="BLOCK">
</xsl:if>

is enough.

Even if you want to know whether there are 4 elements or not, you don't need to count them:

<xsl:if test="BLOCK[4]">
</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().

Regards,

Joerg
