If you consume the file one line at a time, which is what a file input does by default, then many of your lines will not be valid XML and the xml filter will not parse them. For example ...
<measInfo measInfoId="PM=1,PmGroup=FieldReplaceableUnit">
is not a valid XML document, since the opening measInfo tag is not closed.
If you want to consume the whole file as one event then this post shows you how to do it.
