JSOUP - troubles with extracting values from two divs

Question

Hi I trying to get values from two hidden inputs. (__VIEWSTATE and __EVENTVALIDATION)

<form name="FormLogin" method="post" action="Same.aspx" id="FormLogin">
<div>
<input type="hidden" name="__OTHER" id="__OTHER" value="SOME not importent value" />
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/someLongValuewhatIwant=" />
</div>
<div>
<input type="hidden" name="__EVENTVALIDATION" id="__EVENTVALIDATION" value="/someOtherValueWhatIwant" />
</div>
</form>

My code

  doc = Jsoup.connect("http://example.com/index.aspx").get();
            Elements input = doc.select("input[type=hidden]");
            Element viewst = input.select("#__VIEWSTATE").get(0);
            Element eventvd = input.select("#__EVENTVALIDATION]").get(0);
            viewstate = viewst.val();
            eventvalidation = eventvd.val();

But I always got only __VIEWSTATE value and my app crashed when i try to get __EVENTVALIDATION value. Can someone please explain me why ? and How to make it work ?

Answer 1

Jsoup always crashes android when the select matching expression cannot match any element in the given doc which in your case#__EVENTVALIDATION in not on your input element. Check in your Elements input if #__EVENTVALIDATION exists.

Btw:In your code you can directly access any element by selecting #id tag. for example

doc = Jsoup.connect("http://instantgram.ic.cz/index.html").get();


Elements eventvd = doc.select("input[id =__EVENTVALIDATION");
