I think RHTMLForms works if you have a single form, but I have not been
able to see how to use it when you need to go through a sequence of
dynamically generated forms (like you can do with Python mechanize).

want.

I don't know of an easy way to do this in R. I've been doing
something similar with python scripts called from R. If anyone knows
how to do this with just R, I would appreciate hearing too.

Hi. I'm trying to write an application to retrieve financial data
(specially bonds data) from FINRA. The web page is served
dynamically
from an asp.net <http://asp.net> application:
http://cxa.gtm.__idmanagedsolutions.com/finra/__BondCenter/AdvancedScreener.__aspx
<http://cxa.gtm.idmanagedsolutions.com/finra/BondCenter/AdvancedScreener.aspx>
I'd like to know if it's possible to fill dynamically the web page
form from R and, after filling it (with the issuer name),
retrieve the
web page, parse the data, and covert it to appropiate R objects.
For example, suppose I want to search data for AT&T bonds. I'd
like to
know if it's possible, within R, to fill the page served from:
http://cxa.gtm.__idmanagedsolutions.com/finra/__BondCenter/AdvancedScreener.__aspx
<http://cxa.gtm.idmanagedsolutions.com/finra/BondCenter/AdvancedScreener.aspx>
select the "corporate" option and fill with AT&T the field for
"Issuer
name", ask the page to display the results, and retrieve the results
for each of the bonds issued by AT&T (for example:
http://cxa.gtm.__idmanagedsolutions.com/finra/__BondCenter/BondDetail.aspx?ID=__MDAxOTU3Qko3
<http://cxa.gtm.idmanagedsolutions.com/finra/BondCenter/BondDetail.aspx?ID=MDAxOTU3Qko3>)
and parsing the data from the web page.
Thanks in advance.
