xml and generating xpaths

[rich]

I'm wondering if anyone has any advice on processing xml docs (pref. in python).

I'd like to turn a xml doc into a list of xpaths relating to each bit of data. Something like

<apple>
<size>4</size>
<colour>blue</colour>
</apple>
<plum>
<size>2</size>
<colour>pink</colour>
</plum>

would be turned into
/apple/size
/apple/colour
/plum/size
/plum/colour

It sounds like a perfectly reasonable thing to do, but I cannot find a function that I can recycle.


Anyone ?

cheers,
Rich

There are different ways you could do it, but I would think using one of the SAX APIs to blitz through the document would work. You would basically create a stack of tag names, and when you reached a text node, you could contstruct the path from the current stack.

Something in xml.parsers.expat or xml.sax should do the trick, I think.
