< Hi,
<
< I want to check if an optional element is present in my XML document and
< if so I want to react to this fact. For example I have an optional
< element subsidiary in my Organesation.xml. If a subsidiary is present I
< want to create an additional column in my HTML table. How could I
< realise this test. The element-available() function does only apply to
< instruction elements I think?!
<
< Best regards,
<
< Nick
