REALLY simple xml reader

Simon Pickles

1/27/2008 5:35:00 PM

Hi

Can anyone suggest a really simple XML reader for python? I just want to
be able to do something like this:

xmlDoc = xml.open("file.xml")
element = xmlDoc.GetElement("foo/bar")

.... to read the value of:

<foo>
<bar>42</bar>
</foo>


Thanks

Simon

Since python2.5, the ElementTree module is available in the standard
lib. Before 2.5, you can of course install it.

Your code then would look like this:

import xml.etree.ElementTree as et


doc = """
<foo>
<bar>42</bar>
</foo>
"""

root = et.fromstring(doc)

for bar in root.findall("bar"):
print bar.text

>>> from xml.etree import ElementTree as ET
>>> tree=ET.parse('file.xml')
>>> tree.find('bar').text
'42'
>>>

That's not an XML document, so what about it?

What about :

doc = """
<moo>
<bar>99</bar>
</moo>
<foo>
<bar>42</bar>
</foo>
"""
