Hi,
I'm looking for a way to allow user selection of an XML fragment (with a couple of fragments to choose between), with this fragment then being incorporated into the returned output document. At its simplest, this is a selection widget of some kind, depending on the selection I'll see one of two XML fragments appearing as output. Those fragments are themselves defined within the instance data for the form.
With XForms, this could be handled with
<xf:select1 .....>
...
<xf:itemset .../>
<xf:copy ..../>
</xf:select1>
which will select a node from the itemset (including all descendant children, attributes etc.) and copy it into the output instance. The JXForms page suggests itemset supports use of 'value', but not of 'copy' - is that right? Unfortunately 'value' gives me a flattened - simpleContent - output, I need the complexContent that 'copy' provides.
So - is there any way to achieve this using CForms? The best I've come up with so far is to escape the fragments to produce simpleContent strings, so that
<a><b/></a>
becomes
<a><b/></a>
Clearly this has to happen at the point the fragments are presented to the user, but I was hoping to avoid escaping until this point and keep with usable XML that could travel through pipelines for the rest of the process - in particular, keeping the instance data clean.
Any suggestions?
Thanks, Thomas.
PS: If you can't see how this could work in CForms/JXForms, what would you use to escape the XML? Use the Java StringEscapeUtils - http://wiki.apache.org/cocoon/XMLProcessingHowTo - or code it in XSLT?
