only a simple xml reader <tag:id>value </tag:id>

[martijn]

H!,

Is it possible to get a <tag:id>value </tag:id> value ?

When I do this:
-----------------------------------------------------
theXML = """<?xml version="1.0"?>
<title>The Fascist Menace</title>
"""
import xml.dom.minidom as dom
doc = dom.parseString (theXML)
print doc.getElements ByTagName('titl e')[0].toxml()

I get : <title>The Fascist Menace</title> thats oke for me
-----------------------------------------------------

But the xmlfile I must read have other tags:
theXML = """<?xml version="1.0"?>
<title:id>The Fascist Menace</title:id>
<title:name>b la la etc</title:name>
"""

how to get that values ?
I try things like:
print doc.getElements ByTagName('titl e:id')[0].toxml() <--error

Thanks,
GC-Martijn

Addressing your general question, unfortunately you're a bit stuck.
Minidom is rather confused about whether or not it's a namespace aware
library. Addressing your specific example, I strongly advise you not
to use documents that are not well-formed according to Namespaces 1.0.
Your second example is a well-formed XML 1.0 external parsed entity,
but not a well-formed XML 1.0 document entity, because it has multiple
elements at document level. It's also not well-formed according to
XMLNS 1.0 unless you declare the "title" prefix. You will not be able
to use a non XMLNS 1.0 document with most XML technologies, including
XSLT, WXS, RELAX NG, etc.

If you have indeed declared a namespace and are just giving us a very
bad example, use:

print doc.getElements ByTagNameNS(tit le_namespace, 'id')

I'm newbie with that xml stuff.

The only thing I must read is the response I get from a EPP server.
A response like this:

what is the official/best way to handle/parse such xml response ?

Thats maybe a better question

try something like this:

import xml.dom.minidom as dom
doc = dom.parseString ("""<?xml version="1.0"?>
<title>The Fascist Menace</title>""")
print doc.getElements ByTagName('titl e')[0].childNodes[0].data

So to get the msg, you can do:

print doc.getElements ByTagName('msg' )[0].toxml()

But to get the domain:name you have to use the declared namespace:

print
doc.getElements ByTagNameNS('ht tp://www.eurid.eu/xml/epp/domain-1.0',
'name')[0].toxml()

Or you can make life a bit easier with Amara [1]:

import amara
doc = amara.parse(the XML)
print doc.response.re sult.msg #to get the text content
print doc.response.re sult.msg.xml() #to get the XML source for that
element
print doc.response.re sData.appData.n ame
print doc.response.re sData.appData.n ame.xml()
