Wie erhält man den Wert dieser Klasse in jsoup?

Question

Ich möchte den Wert von pricecell/WebRupeeKlasse aus diesem HTML-Dokument.

Das Dokumentausschnitt sieht so aus.

<tr prodid="143012" class="tablerow style2"> 
      <td class="pricecell"><span class="WebRupee">Rs.</span> 29 <br><font style="font-size:smaller;font-weight:normal"> 3 days </font></td> 
      <td class="spacer"></td> 
      <td class="detailcell"><span><span class="label label-default" style="background-color:#3cb521;color:#fff;border:1px solid #3cb521">FULL TT</span>&nbsp; </span><span><span class="label label-default" style="background-color:#fff;color:#0c7abc;border:1px solid #0c7abc">SMS</span>&nbsp; </span> 
      <div style="padding-top:5px"> 
       29 Full Talktime 
      </div> 
      <div class="detailtext"> 
       5 Local A2A SMS valid for 1 day 
      </div></td> 
      </tr> 
      <tr prodid="127535" class="tablerow style2"> 
      <td class="pricecell"><span class="WebRupee">Rs.</span> 59 <br><font style="font-size:smaller;font-weight:normal"> 7 days </font></td> 
      <td class="spacer"></td> 
      <td class="detailcell"><span><span class="label label-default" style="background-color:#3cb521;color:#fff;border:1px solid #3cb521">FULL TT</span>&nbsp; </span><span><span class="label label-default" style="background-color:#fff;color:#0c7abc;border:1px solid #0c7abc">SMS</span>&nbsp; </span> 
      <div style="padding-top:5px"> 
       59 Full Talktime 
      </div> 
      <div class="detailtext"> 
       10 A2A SMS valid for 2 days 
      </div></td> 
      </tr> 
      <tr prodid="143025" class="tablerow style2"> 
      <td class="pricecell"><span class="WebRupee">Rs.</span> 99 <br><font style="font-size:smaller;font-weight:normal"> 12 days </font></td> 
      <td class="spacer"></td> 
      <td class="detailcell"><span><span class="label label-default" style="background-color:#3cb521;color:#fff;border:1px solid #3cb521">FULL TT</span>&nbsp; </span> 
      <div style="padding-top:5px"> 
       99 Full Talktime 
      </div> 
      <div class="detailtext"> 
       10 Local A2A SMS for 2 days only 
      </div></td> 
      </tr> 

Ich möchte speziell die 29 Wert, 59, 99, die in der pricecell-> webrupee Klasse eingeschlossen sind, muss ich es von jsoup analysiert werden.

Der Code, den ich versucht habe: -

class kp extends AsyncTask<Void,Void,Void> { 
      ArrayList<HashMap<String, String>> arraylist2 = new ArrayList<>(); 
      @Override 
      protected void onPreExecute() { 
       super.onPreExecute(); 

      } 
      @Override 
      protected Void doInBackground(Void... voids) { 
       try { 
        Document doc = Jsoup.connect("http://www.ireff.in/plans/" + operator+"/" + state).userAgent("Mozilla/5.0 " + 
          "(Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.101 Safari/537.36").get(); 
        int count = 0, j = 0, i = 0;  
        String TopupTable=""; 

        for (Element table : doc.select("div[id=Topup]")) { 
         for (Element row : table.select("tr")) { 
          count++; 

          TopupTable=TopupTable+row.toString();//has all the values of topup category 

          System.out.print(TopupTable+"TopupTable row string here"); 
         } 

        } 

    .... 
    .... 
    .... 
        Elements r2; 
        String temp; 
        Document doc2 = Jsoup.parse(TopupTable, "",Parser.xmlParser());//doc2 has the TopupTable string converted to a "Document" type variable 
        for (Element table : doc.select("div[id=Topup]")) { 
         for (Element row : table.select("tr")) { 
          i++; 
          j++; 
          k++; 


          try { 
           Elements tds = row.select("td:not([rowspan])"); 
           if(tds.contains("tr[id=download]")) 
            continue; 

    Elements tds2 = doc2.getElementsByClass("td[class=pricecell]"); 
temp=doc2.getElementsByClass("span[class=WebRupee]").toString();//trying to get those numeric values and store it in temp variable 
             System.out.print(temp+"temp var"); 

I Leerwert für die temporäre Variable immer bin, mir freundlich sagen, wo ich falsch gehen.

Vielen Dank für Ihre Zeit :-) Wenn Sie mehr Details zu dieser Frage, bitte unten kommentieren.

Answer 1

Verwenden Sie einfach selectors und org.jsoup.nodes.Element.ownText(), um den Zellentext ohne den untergeordneten Text zu extrahieren.

Ruft den Text ab, der nur diesem Element gehört; erhält nicht den kombinierten Text aller Kinder.

 Document doc = Jsoup 
      .connect(url) 
      .userAgent(userAgent) 
      .get(); 

    Elements cells = doc.select("td.pricecell"); 

    ListIterator<Element> itr = cells.listIterator(); 
    while (itr.hasNext()) { 
     Element cell = itr.next(); 
     System.out.println(cell.ownText()); 
    } 

Ausgabe

29 
59 
99 

Answer 2

Sie können Node.childNodes verwenden, um die List von Node Objekte abzurufen und die Instanz von jedem von ihnen prüfen (in Ihrem Fall TextNode):

Document doc = Jsoup.parse(html); 
Elements trs = doc.select("table tr"); 
for (Element tr : trs) { 
    Element priceCell = tr.select(".pricecell").first(); 
    for (Node child : priceCell.childNodes()) { 
     if (child instanceof TextNode) { 
      System.out.println(((TextNode) child).text().trim()); 
     } 
    } 
} 

Answer 3

ich versucht habe, wie dies für mich arbeiten:

public class Test { 
    public static void main(String[] args) { 
     String parseText = "<table><tr prodid=\"143012\" class=\"tablerow style2\">\n" + 
       "   <td class=\"pricecell\"><span class=\"WebRupee\">Rs.</span> 29 <br><font style=\"font-size:smaller;font-weight:normal\"> 3 days </font></td>\n" + 
       "   <td class=\"spacer\"></td>\n" + 
       "   <td class=\"detailcell\"><span><span class=\"label label-default\" style=\"background-color:#3cb521;color:#fff;border:1px solid #3cb521\">FULL TT</span>&nbsp; </span><span><span class=\"label label-default\" style=\"background-color:#fff;color:#0c7abc;border:1px solid #0c7abc\">SMS</span>&nbsp; </span>\n" + 
       "    <div style=\"padding-top:5px\">\n" + 
       "    29 Full Talktime \n" + 
       "    </div>\n" + 
       "    <div class=\"detailtext\">\n" + 
       "    5 Local A2A SMS valid for 1 day \n" + 
       "    </div></td>\n" + 
       "   </tr>\n" + 
       "   <tr prodid=\"127535\" class=\"tablerow style2\">\n" + 
       "   <td class=\"pricecell\"><span class=\"WebRupee\">Rs.</span> 59 <br><font style=\"font-size:smaller;font-weight:normal\"> 7 days </font></td>\n" + 
       "   <td class=\"spacer\"></td>\n" + 
       "   <td class=\"detailcell\"><span><span class=\"label label-default\" style=\"background-color:#3cb521;color:#fff;border:1px solid #3cb521\">FULL TT</span>&nbsp; </span><span><span class=\"label label-default\" style=\"background-color:#fff;color:#0c7abc;border:1px solid #0c7abc\">SMS</span>&nbsp; </span>\n" + 
       "    <div style=\"padding-top:5px\">\n" + 
       "    59 Full Talktime \n" + 
       "    </div>\n" + 
       "    <div class=\"detailtext\">\n" + 
       "    10 A2A SMS valid for 2 days \n" + 
       "    </div></td>\n" + 
       "   </tr>\n" + 
       "   <tr prodid=\"143025\" class=\"tablerow style2\">\n" + 
       "   <td class=\"pricecell\"><span class=\"WebRupee\">Rs.</span> 99 <br><font style=\"font-size:smaller;font-weight:normal\"> 12 days </font></td>\n" + 
       "   <td class=\"spacer\"></td>\n" + 
       "   <td class=\"detailcell\"><span><span class=\"label label-default\" style=\"background-color:#3cb521;color:#fff;border:1px solid #3cb521\">FULL TT</span>&nbsp; </span>\n" + 
       "    <div style=\"padding-top:5px\">\n" + 
       "    99 Full Talktime \n" + 
       "    </div>\n" + 
       "    <div class=\"detailtext\">\n" + 
       "    10 Local A2A SMS for 2 days only \n" + 
       "    </div></td>\n" + 
       "   </tr></table>"; 

       Document doc = Jsoup.parse(parseText); 
       doc.select("font").remove(); 
       doc.select("span").remove(); 
      for (Element row : doc.select("tr")) { 
       Elements tds = row.select("td.pricecell"); 
       Whitelist wl = Whitelist.basic(); 
       String value = Jsoup.clean(tds.get(0).text(), wl); 
       System.out.println(value); 
      } 

    } 
} 

Ausgang:

29 
59 
99
