Question

我想用jsoup解析一个html表。

我要解析的html页面的一部分：

SELECT [Id], [Title] FROM WorkItems WHERE State<>'Closed' AND AttachmentCount<>0

我如何选择所有＆＃34; tr＆＃34;在（包括）带有id＆＃34; RContents＆＃34;？的tr之后的元素我尝试了<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> <td class="dkHeading">A6</td> <td class="dkHeading">A7</td> </tr> <tr id="RContents"> <td class="dkTextCenter">B1</td> <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>，但这确实无效。

Answer 1

您可以使用下一个兄弟选择器〜：

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

Answer 2

您可以选择tr Elements，然后选择loop。因为元素是按顺序你可以尝试这样的东西：

    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
        }
    }

Jsoup在第一个元素之后选择元素
