xml.dom.minidom question

[Geiregat Jonas]

I'm using xml.dom.minidom , I get some data by using
obj.getElements ByTagName("name ")[0] then I have an object, but how can I
get the data between the tags ? I could do .toxml() and then strip it
away. But is there a better way maybe a function made for it ?
Also is it possible using the xml.dom.minidom module to create modify an
xml file ?

Given <name>Greg</name>, 'Greg' is considered an element inside the 'name'
element. So, all you have to do is go one level of elements deeper.

myname = obj.getElements ByTagName("name ")[0].childNodes[0].data

Might want to read up about normalization, too.

Re: xml.dom.minidom question

What do you mean by normalization ?

Search for the normalize method in here:

Actually, Peter, that link has nothing to do with the normalization of
text nodes in a DOM, which was, I think, the "normalizat ion" in
question.

The link you have provided gives detail on "attribute value
normalization", which is the normalization of whitespace in attribute
values, not DOM text nodes.

Of course, the normalization of test nodes in a DOM is a not a part of
the XML spec, it is a part of the DOM spec.

http://www.w3.org/TR/DOM-Level-2-Core/core.html

Check out the Node.normalize( ) method.

Re: xml.dom.minidom question

so What about writing modifying a xml file with minidom ?

Quoting Geiregat Jonas (eniac@sdf-eu.org):[color=blue]

from xml.dom.minidom import parse

dom = parse(my_xml_fi le)

dom = makeChangesToMy DomTree(dom)

f = open(my_xml_fil e)
f.write(dom.tox ml())

You should verify that this works properly but it should. I remember
at one point observing a problem with a document that declared a DTD,
where the DTD was not preserved and invalid XML was dumped. I don't
remember if minidom was the parser I was using, though, and I don't
have the time to test right now.

You mean it's considered a text node inside of the 'name' element
node.

I'll point out that it might actually be more than one text node.
Only safe way is to use the normalize() method.

Better yet, why torture yourself with DOM API, especially when all you
need is to extract data from XML files?

My recommendations would be to use Anobind, Elementtree,
gnosis.xml.obje ctify or 4XPath (an advanage of XPath is that at least
the extraction expression is ross-language):

Anobind:

Elementtree:

gnosis.xml.obje ctify:
