i want to parse a html table with jsoup.

part of the html page i want to parse:

<tr>
    <td class="dkHeading">A1</td>
    <td class="dkHeading">A2</td>
    <td class="dkHeading">A3</td>
    <td class="dkHeading">A4</td>
    <td class="dkHeading">A5</td>

<tr id="RContents">

    <td class="dkTextCenter">B2</td>
    <td class="dkTextCenter">B3</td>
    <td class="dkTextLeft">B4</td>
    <td class="dkTextCenter">B5</td>
    <td class="dkTextCenter">B6</td>
    <td class="dkTextCenter">B7</td>
  </tr>
  <tr>
    <td class="dkTextCenter">C1</td>
    <td class="dkTextCenter">C2</td>
    <td class="dkTextCenter">C3</td>
    <td class="dkTextLeft">C4</td>
    <td class="dkTextCenter">C5</td>
    <td class="dkTextCenter">C6</td>
    <td class="dkTextCenter">C7</td>
  </tr>
  <tr>
    <td class="dkTextCenter">D1</td>
    <td class="dkTextCenter">D2</td>
    <td class="dkTextCenter">D3</td>
    <td class="dkTextLeft">D4</td>
    <td class="dkTextCenter">D5</td>
    <td class="dkTextCenter">D6</td>
    <td class="dkTextCenter">D7</td>
  </tr>

how can i select all "tr" elements after (and including) that tr with id "RContents"? i tried doc.select("tr[id=RContents] > tr"); but that did't work.

Answer 1

您可以使用下一个兄弟姐妹选择器~：

doc.select("tr[id=RContents] ~ tr");

Answer 2

you can select tr Elements , then loop through them. since the elements are in order you can try something like this:

    Document document = Jsoup.parse("YOURHTML");

    Elements elements = document.select("tr");

    boolean start=false;
    for(Element e : elements){
        if(e.hasAttr("id") && e.attr("id").equals("RContents"))){   
            start=true;
        }

        if(start){
         //all tr elements including id=RContents and after
        }
    }
