Hello,
If a script that uses mechanize fails to find an html node that has
been identified with Firebug, this is probably because that node has
been autogenerated (provided that the expression to get the node is
correct).
As an alternative to verify this, you can try to download the html
page and open it in your favourite editor. If some of the nodes that
you can see in your browser are missing or empty, then one of the
JavaScript scripts in the page should have created/populated it.
If you're in doubt, you can try to use mechanize and, if you have
problems such as the described above, then you can move to windmill or
some other tool that executes JavaScript code before trying to get the
desired data.
Best regards,
Javier
