Retrieving data from aspx pages

I haven't used it extensively myself, and can't speak to it's current
state but on quick inspection RHTMLForms seems worth a look for what you
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.
