TransformerException in discovery parsing HTML for META tag

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Try discovery on http://edevil.livejournal.com

What is the expected output? What do you see instead?

The expected output would be to find 

<meta http-equiv="X-XRDS-Location"
content="http://edevil.livejournal.com/data/yadis" />

which is on the page but I think it fails because of this line in the HTML:
<span class='ljuser' lj:user='edevil' style='white-space: nowrap;'>

Notice the lj: prefix in the attribute name.

What version of the product are you using? On what operating system?
Rev: 556

Please provide any additional information below.

Also, trowing a RuntimeException when there's a problem parsing a page is 
unnecessary
I think. :)
