[xml] Getting Node content with markup

[Ben Gamari <ben milkyway0 dyndns org>]

Hi,

I am implementing a python library to modify an XML-based documentation 
format which must be able to handle XML such as this:
    <Function name="foo">
      <Description>The function <FuncName>foo</FuncName> modifies the 
variable <VarName>bar</VarName> etc.</Description>
    </Function>
Instead of creating classes for the <FuncName> and <VarName> elements I 
would like to pass the inner xml of the <Description> element directly 
to the user. I'm using the tree API and haven't found a suitable 
function. However, when I was looking at the XMLReader API I found the 
xmlTextReaderReadInnerXml and xmlTextReaderReadOuterXml functions but 
unfortunately they are unimplemented. If I have to I could write code 
to reconstruct the tags from the tree but I would much rather not have 
to undo the work of the parser. Does anyone know of a way to get the 
inner xml of an element with the tree api or know if and when this will 
be implemented. I might be able to donate an implementation if you are 
interested in it.

    Thanks,
