RE: check if a node is empty

Hi Jeremy,

the test for empty node elements would be:

<xsl:when test="node[not(*)]">
  ... whatever happens when node is empty
</xsl:when>

Some more examples:

..  test="node[not(a)]"

will be true only if node does not contains an <a> node

..  test="node[a]" 

will be true only if node contains an <a> node

Hope that helps.

cheers

Malcolm

Subject:  check if a node is empty


Hi all,
      I have done some preliminary research, but perhaps I am making this
harder than it is (or perhaps I have not asked the right questions of the
knowledge base)

Here is my problem:

I have an XML document that may contain nodes with no children

      <node>
      </node>

I need to test if this is the case in my XSL in order to output the correct
information

      <xsl:choose>
            <xsl:when test .... >
                  do some process here
            </xsl:when>
            <xsl:otherwise>
                  no process to do
            </xsl:otherwise>
      </xsl:choose>

I am sure it is simple so if someone could point me in the right direction
or give a bit of a clue I am very appreciative.

Thanks in advance

Jeremy
