[xsl] generic sorting problem

["peter willard donisthorpe" <paytur@xxxxxxxxxxx>]

hi,

I'm having problems with a sort.

I wish to sort some xml, and indent the result. I can do the indent, but the 
sorting is proving a problem.

My xml will be in the format of the below, though the element names may 
differ per document.

<xml>
<root_elem>
  <item_elem>
     <value1> xyz</value1>
     <value2> asd </value2>
     ...
  </item_elem>
  <item_elem>
     ...
  </item_elem>
</root_elem>

I want to sort all the "item_elem" elements based on the value of the 
"value1" sublements.

As per abovve, the names of these elements are dynamic, and this is where I 
am having difficulty.
I.e., in another document, "root_elem", "item_elem" and "valueX" could have 
different names, but the structure is the very same.

I need to sort the children of the root element by _their_ first child.

Is there a generic way to do this ?

Can the result be indented in the same operation ?

Any help appreciated.

Peter
