xml does not allow text in a <key> node. So you kneed to place a <text> node
inside the <key> node. Like such

<key><Text>42</Text></key>

xml is also case sensitive. So the T in Text must be capital.

If you do not want to edit your xml file this will get you what you want.

print tdict.childNodes[1].firstChild
print tdict.childNodes[1].firstChild.nodeValue

will output

<DOM Text node "42">
42

The xml turns white space into a text node. So the whitespace between
"<key>42</key>" and "<dict> ... </dict>" got parsed into a text node. Which
is "tdict.childNodes[2]".

"<dict> ... </dict>" Would be the value of "tdict.childNodes[3]".
