Parsing subchilds in XML with ElementTree

Question

Im trying to extract information from a XML-document with ElementTree in Pyhton 3.2.

The XML looks like this:

<Page Id="1">
    <Group>4</Group>
    <Type>
        <Letter>B</Letter>
        <Number>101</Number>
        <Deep>
            <A>900</A>
            <B>900</B>
        </Deep>
    </Type>
</Page>

I manage to get the elementdata from "Group" with:

for Page in root.iter('Page'):
     Group = Page.find('Group').text

And "Letter"-data with:

for Type in root.iter('Type'):
     Dim = Type.find('Letter').text

However I can't figure out how to get the data from the subchilds of "Deep" (A and B). All help is greatly appreciated!

Answer 1

You are very close. Use find to find the Deep tag and the iterate over it.

Ex:

import xml.etree.ElementTree as ET
tree = ET.parse(filename)
root = tree.getroot()
for Type in root.iter('Type'):
    for deep_tag in Type.find("Deep"):
        print( deep_tag.text )

Output:

900
900
