Re: remove empty content from xml output at xform submission

Hi Bryan,

I think this can be done (up to a certain point) through the

xforms:relevant MIP. I have attached a test document that
demonstrates 
the basic approach:

The structure of the instance is like this:

<root>
   <e1>
     <sub></sub>
   </e1>
   <e2>
     <sub></sub>
   </e2>
</root>

There is a binding that binds to every child of the
root-element, that 
says that the node is only relevant if the text content of
the element's 
"sub"-child is non-empty:

<xf:bind nodeset="/root/*"
relevant="string-length(./sub)>0"/>

Now, if only the second "sub"-element has text
content (aaa) the 
following XML is submitted:

[d:]type sub2.xml
<?xml version="1.0"?>
<root><e2><sub>aaa</sub></e2>&
lt;/root>

Note that e1 is not submitted, because it got marked with
relevant=false.

Cheers,
Lars
