I cannot select <title> tag in Atom XML using jQuery.

Question

I get a Google Picasa web albums' atom data through Ajax using jQuery. This atom data looks like this:

http://code.google.com/apis/picasaweb/docs/2.0/developers_guide_protocol.html#ListAlbums

When I write

$(xhr).find('entry id').eq(0).html();

it is OK.

But

$(xhr).find('entry title').eq(0).html();

does not select

The <title> tag exists.

Please tell me how to resolve this problem. Thank you!
