XML_RSS: accessing to attributes and subnodes

[BlueHeaven]

Please can someone tell me if with pear XML_RSS I can access to attribute values and how?
example:
<item about="9632">
I would like to retrieve "about" value.

And I have a secon question.
In my rdf document I have severals "image" elements UNDER the each "item" element (they are subnodes). I need to access to those image elements for each item. The getImages() function is unuseless because it gets all the images together and it cannot be understood which element they belong to.
example:
<item rdf:about="http://www.atpress.ne.jp/view/9632">
<dc:date>2008-11-11T13:22:27+09:00</dc:date>
<title>Here the title</title>
<link>http://www.xyz.com/view/9632</link>
<description>bla bla bla</description>
<image rdf:about="http://www.xyz.com/uploadimages1fd491a1eb4.jpg">
<title>img1</title>
<url>http://www.atpress.ne.jp/uploadimages/1fd491a1eb4.jpg</url>
</image>
<image rdf:about="http://www.xyz.com/uploadimages1fd491a1eb7.jpg">
<title>img2</title>
<url>http://www.atpress.ne.jp/uploadimages/1fd491a1eb7.jpg</url>
</image>
<image rdf:about="http://www.xyz.com/uploadimages1fd491a1eb1.jpg">
<title>img3</title>
<url>http://www.atpress.ne.jp/uploadimages/1fd491a1eb1.jpg</url>
</image>
</item>

PS: As I needed to access to other item subelements not mentioned above and not included in the "default" list. So I added those ones to the $itemTags array (rss.php), and everything perfectly works. But if I add the index "IMAGE" it causes an"undefined index" error. WHY???

Thank you very much you will give me an help.
