Trying to use the Nokogiri Sax parser. I ran into a problem parsing  
the following:

It chokes on the x="" attribute.

That’s because it’s not valid xml (or html). You’d need to escape the  
\< and \>

\<try x="\<x/\>: /\>

Can you be more specific? Are you using the XML SAX parser, or the HTML  
SAX parser? What version of libxml2 do you have?

I tried this document with the HTML SAX parser, and it seemed to handle  
it just fine.

Ah that was it then. I was using the XML SAX parser and I did not  
realize that \< \> had to be escaped in attributes. What was happing was  
the document would basically get cut off after it reached the  
attribute.

The HTML SAX parser handled it without a problem though.

My LibXML version is 2.6.31, btw.

Thanks,
