Re: Generating Xml with CGI

[Vernon Hamberg <vhamberg@xxxxxxxxxxxxxxx>]

Hi

If you have a variable in your template, you always have to set it to 
something - otherwise you get this **Missing data** content there. Or 
another default that you can set, if I recall rightly.

If you can have the XML element empty, just pass the empty string in the 
UpdHTMLVar procedure call - the string with 2 quotes and nothing in between.

If you need to leave out empty elements, I suggest that you have a 
sections for <mytag> only - then a section for the stuff before <mytag> 
and another for the stuff after <mytag>..

So something like this:

<!-- $contentbeforemytag$ -->
    your XML content that comes before "mytag"
<!-- $mytag$ -->
<mytag><!-- %mytagcontent% --></mytag>
<!-- $contentaftermytag$ -->
   you XML content that comes after "mytag"

Then in your RPG you use an IF block to control whether to 
WrtSection('mytag')

Another way is to have 2 sections for the entire content - one has 
"mytag", the other does not contain "mytag". This could be easier to 
understand but has more things in the template.

You need to be sure that the XML content is valid when you leave out the 
"mytag" element.

I have used the both methods.
