When feeding an parser with a tag in which its arguments contain a < (as in <a href='http://www.example.org/"<;'>example</a> the SGMLParsers doesn't handle the data/arguments correcly. For example, with the above string I get:

Fed: <a href='http://www.example.org/">;'>example</a>
Tag opened: a
Arg  href  ->  http://www.example.org/">;
Arg escaped 'http://www.example.org/">;'
Data: ;'>example
Tag closed: a

I have attached a small example.

I'm using python2.5.1

Cheers,

Álvaro.

Confirmed in trunk.

Can we close this as sgmllib only supported htmllib which has been superseded by HTMLParser?
