Yes.

I think you need XSLT to do this. Luckily, libxslt is available. You 
just read and parse the original XML file, then apply your XSL style 
sheet to it.

Again, XSLT might be your friend here. There have been lots of threads 
on the subject of document merging on the Mulberry Tech XSL list. Check out:
http://www.mulberrytech.com/xsl/xsl-list/

You can get high quality help here. My personal experience with libxslt 
used in conjunction with libxml2 has been very good. It works very well.

So you would have a template file that looks like this:
<hostName>
       <defaultValue></defaultValue>
       <description>
              <shortDescr></shortDescr>
              <longDescr></longDescr>
       </description>

       <dataType></dataType>
       <operations></operations>

</hostName>

and, according to your example, you want to insert these values:
value
Hostname descr.
long descr of Hostname
string
set,delete

into the proper places in the DOM structure.
Or maybe just into the proper places in a text file.
Or maybe as attributes on some element.

Do I understand this correctly?
