Retrieving data from aspx pages

Hi Jose, I think this is more of an r-help question so I'm going to forward your question there: R-devel is really for the development of R itself, not development with R.
Er, no! R help is (mainly) for helping beginners. We usually put the dividing line where the answers would become incomprehensible to many of the list readers. So compiler issues and internal C code is off-limits there, but I'd say that so is HTML and ASP. So unless there happens to be a precooked package that fits the query exactly, I'd say that it belongs here. To wit: "This list is intended for questions and discussion about code development in R. Questions likely to prompt discussion unintelligible to non-programmers or topics that are too technical for R-help's audience should go to R-devel, see the posting guide section."

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 application: 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 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) and parsing the data from the web page. Thanks in advance.
