Android: How to parse a HTML site and take only some specific data?

Question

I have a question:

I have a link: http://wap.nastabuss.se/its4wap/QueryForm.aspx?hpl=Teleborg+C+(V%C3%A4xj%C3%B6) and I wanna take only some specific data from this link and to show in textview in Android.

Is this possible in Android, I mean is there any chance by parsing or I don't know, you can suggest me guys.

For example I just want to take this column Nästa tur (min) from that site.

Regards

JSoup is pretty nice and getting popular. Here's how you could just parse the whole table:

URL url = new URL("http://www.nseindia.com/content/equities/niftysparks.htm");
Document doc = Jsoup.parse(url, 3000);

Element table = doc.select("table[title=Avgångar:]").first();

Iterator<Element> it = table.select("td").iterator();

//we know the third td element is where we wanna start so we call .next twice
it.next();
it.next();
while(it.hasNext()){
  // do what ever you want with the td element here

  //iterate three times to get to the next td you want. checking after the first
  // one to make sure
  // we're not at the end of the table.
  it.next();
  if(!it.hasNext()){ 
    break;
  }
  it.next();
  it.next();
}

Yes, you'll need to add the JSoup jar into you project. – Kurtis Nusbaum Oct 22 '11 at 23:35

i fixed out the importing stuffs, now there is problem in code i guess. – Lulzim Fazlija Oct 23 '11 at 00:13
Beware, I didn't fully check this code. It may not work completely, but it should give you a good idea of where to start. The gist is correct, a few modification may be needed to get it fully working though. – Kurtis Nusbaum Oct 23 '11 at 00:16
at this line: Element table = doc.select("table[title=Avgångar:]").first(); is stucking??? so how can i solve this, i mean can u please explain me a bit what should i check in more detail?? – Lulzim Fazlija Oct 23 '11 at 00:22
is it bc this JSoup maybe doesnt support the letters like å in case of title Avgångar. – Lulzim Fazlija Oct 23 '11 at 00:25
I'm not sure, you should ask another JSoup specific question if you're still having issues. – Kurtis Nusbaum Oct 23 '11 at 01:47

If the parsing seems simple enough and you want you could also use regular expressions to find the correct part of the html. Regular expressions will be useful to know at some point anyway. Using some XML/HTML parsing library is the more flexible way to do it (XMLReader for example).
