[sage-devel] Re: Parsing XML in Sage
I have an spkg for lxml (required for JModelica) and I intend to make it available in the near future. Bill On Tuesday, September 17, 2013 4:45:22 AM UTC-7, Nathann Cohen wrote: Hell everybody !

I would suggest that you start with Python's own xml.etree: import xml.etree.cElementTree as ET tree = ET.ElementTree(file='document.xml') root = tree.getroot() for child in root: print(child.tag, child.attrib) On Tuesday, September 17, 2013 12:45:22 PM UTC+1, Nathann Cohen wrote: Hell everybody !

And I just noticed that .tag and .attrib methods do not appear in the tab-completion. Which may explain a lot of things _ Is there a reason for that ?

Re: [sage-devel] Re: Parsing XML in Sage
Here is an answer
{{{
sage: class A(object):
: def __getattribute__(self, name):
: return name
:
sage: a = A()
sage: a.b
'b'
sage: a.nathann
'nathann'
}}}
Actually, the tab completion looks really funny on this object!

Is there a reason for that ?
