Subject: Re: [xsl] is there a way to output XML with invalid qnames? From: "G. Ken Holman" <gkholman@xxxxxxxxxxxxxxxxxxxx> Date: Fri, 06 Nov 2009 21:07:57 -0500 |
I'm trying to format XML files so that I can display them as examples in a wiki. I'd like the element names in the examples to link to other wiki pages, so I'm trying to figure out the best way to take source like this:
<ns:elementName1> <ns:elementName2>value</ns:elementName2> </ns:elementName1>
And get output like this:
<[ns:elementName1|page 1]> <[ns:elementName2|page 2]>value</ns:elementName2> </ns:elementName1>
Of course, "[ns:elementName|page]" isn't a valid qname so just trying to rename the elements in an XML to XML transform doesn't work.
...
Before I give myself a headache trying to figure it out, I was wondering if anyone could suggest a better approach I should look into.
