[jQuery] context-based selection in internet explorer 7 doesn't work

hello!

 

i have a problem with the context-based selection of elements in a html-string in internet explorer 7.

 

with the following code:

var htmltmp = '<div style="width: 1100px;"><img src="test.gif" width="300" id="testphoto" /></div>';

alert($('#testphoto', htmltmp).attr('width'));

the internet explorer shows "0" and the firefox shows the right "300".

has anybody a workaround or the solution why this doesn't work?

i`m using jQuery 1.3.2

thanks for your attention.
