The problem is because crawl-timestamp-msec is in a different namespace. Somewhere in the document (usually the root element, which looks to be feed in your case), it will have an attribute along the lines of xmlns:gr="http://some/url/here" . This says that the document will be using things from the http://some/url/here namespace, and will prefix all of these things with gr .
