Getting size of a webpage before parsing it
- by user2869844
I am trying to parse a webpage using jsoup and all is working good using this code:
class DownloadSearchResultsTask extends AsyncTask<String, Integer, ArrayList> {
private String link = "link";
private String title = "title";
private String vote = "vote";
private String age = "age";
private String size = "size";
private String seeders = "seeders";
private String leechers = "leachers";
@Override protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
}
@Override protected ArrayList doInBackground(String... params) {
// TODO Auto-generated method stub ArrayList
<HashMap<String, String>> searchResult = new ArrayList<HashMap<String, String>>(); HashMap<String, String> map; String link, title, vote, age, size, seeders, leechers; try { HttpURLConnection httpURLConnection=(HttpURLConnection) new URL("http://www.facebook.com").openConnection(); Log.d("VIVZ", httpURLConnection.getContentLength()+""); } catch (MalformedURLException e1) { // TODO Auto-generated catch block
e1.printStackTrace(); } catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
Document mDocument;
try {
long l1=System.nanoTime();
Log.e("VIVZ",l1+"");
mDocument = Jsoup .connect(params[0]) .userAgent( "Mozilla/5.0 (Windows; U; WindowsNT 5.1; en-US; rv1.8.1.6) Gecko/20070725 Firefox/2.0.0.6") .referrer("http://www.google.com").get();
long l2=System.nanoTime(); Log.e("VIVZ",(l2-l1)+"");
Elements mResults = mDocument.select("div.results dl");
for (Element result : mResults) {
map = new HashMap<String, String>();
Elements elements = result.select("dt a");
for (Element linkAndTitle : elements) {
link = linkAndTitle.attr("abs:href");
title = linkAndTitle.text();
map.put(this.link, link);
map.put(this.title, title);
}
elements = result.select("dd span.v"); for (Element v : elements) { vote = v.text(); map.put(this.vote, vote); } elements = result.select("dd span.a"); for (Element a : elements) { age = a.text(); map.put(this.age, age); } elements = result.select("dd span.s"); for (Element s : elements) { size = s.text(); map.put(this.size, size); } elements = result.select("dd span.u"); for (Element u : elements) { seeders = u.text(); map.put(this.seeders, seeders);
}
elements = result.select("dd span.d");
for (Element d : elements)
{ leechers = d.text();
map.put(this.leechers, leechers);
} searchResult.add(map);
} Log.e("VIVZ", searchResult.toString());
return searchResult;
} catch (IOException e) { // TODO Auto-generated catch block
Log.e("VIVZ",e+"");
} return null;
}
@Override protected void onPostExecute(ArrayList result) { // TODO Auto-generated method stub
super.onPostExecute(result);
}
}
