Python xml.dom, help reading attribute data

2005-09-06 Thread Thierry Lam 
Let's say I have the following xml tag:

para role=success1/para

I can't figure out what kind of python xml.dom codes I should invoke to
read the data 1? Any help please?

Thanks
Thierry

In [20]: import xml.dom.minidom

In [21]: s = '''para role=success1/para'''

In [22]: x = xml.dom.minidom.parseString(s)

In [23]: print x.firstChild.firstChild.data
1


I doubt this really answers what you're really wanting to ask.  And this 
is a really really brittle way of trying to parse XML.  But it answers 
exactly what you're asking.  Hope it gives you the start you need.  Post 
a follow-up when you have more questions.

This is job for xpath.

#-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
from xml import xpath
from xml.dom import minidom

doc = para role=success1/para

mydom = minidom.parseString(doc)
#result_nodes = xpath.Evaluate(/para/text(), mydom)
#result_nodes = xpath.Evaluate(/para[1]/text(), mydom)
result_nodes = xpath.Evaluate(/[EMAIL PROTECTED]'success']/text(), mydom)
for ix, r in enumerate(result_nodes):
   print result %d: %s % (ix, r)
#-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

Xpath support is a part of the PyXML package, which you can get from here

http://pyxml.sourceforge.net

Xpath tutorials from here

If you use elementtree:

 from elementtree import ElementTree
 node = ElementTree.fromstring(para role=success1/para)
 node.text
'1'
 node.attrib[role]
'success'
