find/findtext/findall only look at direct subelements, unless you use xpath-
style syntax.  in this case,


should do the trick.  or you could do something like

    for dir_elem in tree.findall("dirob"):
        for file_elem in dirob.findall("fileob"):
            print file_elem.findtext("filesize")

to loop over all directory objects at the top level, and print the sizes for
all files in those directories.

to get the first filesize in the tree, no matter where it is, use

>      <filename>test.txt</filename>
>      <filesize>10</filesize>
>     </fileob>
>    </dirob>
>  </backup.xml>
