How do I retrieve an element from Atom Feed?

Hi,

I have an atom feed containing the following:
<feed idx:index="no">
...
<entry>
...
<source gr:stream-id="feed/http://www.plantphysiol.org/rss/current.xml">

<id>
tag:google.com,2005:reader/feed/http://www.plantphysiol.org/rss/current.xml
</id>
<title type="html">Plant Physiology current issue</title>
<link rel="alternate" href="http://www.plantphysiol.org" type="text/html"/>
</source>
</entry>
</feed>

... represents other fields ignored.

I am using Perl, XML::Feed which in turn automatically decides whether to use XML::Atom::Feed or XML::RSS depending on which type of feed. In the above case, it is XML::Atom::Feed.

How do I get the 'source' element & sub-elements in the above xml? I looked at the documentation etc. and seemed like $entry->get($ns, $element) needs to be used for the same.
However, I have been running into lot of minor problems.

Any suggestions on how I can do this starting from a given feed, parse an entry and retrieve all the elements & sub-elements of 'source' will be appreciated.

Thanks.
