Hi,

Here is my situation:
I'm using the command line, as in, I'm not starting gnome or kde (I'm on
linux.)
I have a string of text attached to a variable,. So I need to use one of
the browsers on linux, that run under the command line, eg. lynx,
elinks, links, links2 and do the following.
1. Open a certain web page and find the first text box on the page, and
put this text into the form.
2. Press the submit button, and wait for the result page to load.
3. Click on the 15th link down the page.

So, how do I do this, can anyone point me to some docs or modules that
may help out here?

Thank you,

Use the module "mechanize". It will mimic a browser, and allows you to
navigate to pages, fill in forms & submit them.

And with lxml or BeatifulSoup, you can extract the link you need to
press, and then make mechanize visit it.

No, you don't need any text mode browser. It's much easier to do with
modules from the Python standard library.

I assume you know HTML and HTTP.

You can use urllib or urllib2 to submit the form.

You will then get the returned HTML from a function and you will have to
parse it for the link you're interested in. There are many approaches to
get there. Manual parsing, regular expressions or one of the XML parsers
in the standard library (etree is the easiest).

While all of this may seem overwhelming at first, I guess the solution
can be written in 20 - 30 lines of code.

Well, what seemed a very daunting task at first, proved to be quite
easy, after a little bit of research. Thanks very much, I've written my
script, and it works correctly, using the mechanize module.

Thanks for everyone's help
