Mechanize: find form with 'id' rather than 'name'?

Peter Szinek

1/31/2007 11:19:00 AM

This is what I am doing:

my_form = doc.forms.with.name(formname).first

This is what I want:

my_form = doc.forms.with.id(id_string).first

but somehow Mechanize does not like it.

Maybe because id collides with Object.id?

My problem is that the from does *not* have a 'name' attribute in the
html - so apparently I can not use that to locate it - therefore I would
like to use 'id' - or what else should I do?

Thanks,
Peter

I haven't dug into the Ruby Mech yet, but the Perl version lets you
pick the Nth form on the page.

Ruby's should have a Page#forms that works like an array.

Yeah, you can do

my_form = doc.forms[0]

but all I have is the id attribute of the form I am looking for. (i.e.
not the index of the form I am looking for).

So currently I am looping through all the forms and comparing the
current form's id (through form_node.attributes['id']) with the id I am
looking for.

Is there a better way to do this? Or is this OK?

Here's at least one way:
if doc is your instance of WWW::Mechanize:
my_form = (doc.page/:form).find { |elem| elem['id'] == id_string }

(Of course if you did doc = mech_instance.page, then it's
(doc/:form).find ...)

Have you heard any of the stories of engineers who have been out of work
for years? What about all the tool and die makers who workd in auto
manufacturing? Have you heard about them?
