copied!<p>Just use http instead of https and that should solve your problem. Here is the output you get if you try this</p> <pre><code>forms = getHTMLFormDescription("http://www.dmv.ca.gov/wasapp/FeeCalculatorWeb/vlfForm.do", dropButtons = TRUE) </code></pre> <p>[[1]] HTML Form: <a href="http://search.ca.gov/search" rel="nofollow">http://search.ca.gov/search</a> q :[ Search DMV Site ] </p> <p>$feeRequestForm HTML Form: <a href="http://www.dmv.ca.gov/wasapp/FeeCalculatorWeb/vlfFees.do" rel="nofollow">http://www.dmv.ca.gov/wasapp/FeeCalculatorWeb/vlfFees.do</a> vehicleLicense :[ ]<br> vehicleTaxYear : vehicleVin :[ ]</p> <p>Here is an example of how to fill a form and get a data table from a yahoo sports page.</p> <pre><code># get form description url = 'http://ca.sports.yahoo.com/nhl/stats/byteam?cat=teamstats&sort=404' forms = getHTMLFormDescription(url); # create a function using form description, to query the url efun = createFunction(forms[[3]]); # extract webpage by passing required arguments to function page = efun(year = 'season_2009', conference = 'Eastern'); # parse webpage and return html tree doc = htmlTreeParse(page, asText = T, useInternalNodes = T); # extract table from the html tree tab = readHTMLTable(doc); </code></pre> <p>I applied this to the webpage you specified, but for some reason the form element VehicleTaxYear is returned incorrectly which causes errors. Someone with a more in-depth knowledge of HTML forms would be able to guide you on how to debug this error.</p> <p>Hope this is useful</p> <p>EDIT. I fixed an error. It should be <code>createFunction(forms[[3]])</code>, since we are only interested in the third form.</p>
