Java Jsoup搜索

Question

我對Jsoup有一些疑問。 我有以下父頁面。 我想在HTML頁面上尋找一些標簽名稱，如果找到了它們，我想進入鏈接的標簽名稱內並搜索更多的標簽名稱。 但是首先，我想在控制台中給我標簽名稱。 這是我的HTML頁面。

    <div id="main">


<div class="box">
<!-- box / title -->
<div class="title">
<h5>
<input class="q_filter_box" id="q_filter" size="15" type="text" name="filter" placeholder="quick filter..." value=""/> 
<span class="groups_breadcrumbs">
<a href="/">Home</a>
&raquo; "samia" with
</span>
<span id="repo_count">0</span> repositories
</h5>
<ul class="links">
<li>

</li>
</ul>
</div>
<!-- end box / title -->
<div class="table">
<div id='groups_list_wrap' class="yui-skin-sam">
<table id="groups_list">
<thead>
<tr>
<th class="left"><a href="#">Section Name</a></th>
<th class="left"><a href="#">ID_Description</a></th>
</tr>
</thead>

<tr>
<td>
<div style="white-space: nowrap">
<a href="/samia/Export"><i class="icon-folder-close"></i> Export</a>
</div>
</td>
<td>samia/Export group</td>
</tr>
<tr>
<td>
<div style="white-space: nowrap">
<a href="/samia/Links"><i class="icon-folder-close"></i> Links</a>
</div>
</td>
<td>samia/Links group</td>
</tr>
<tr>
<td>
<div style="white-space: nowrap">
<a href="/samia/Platforms"><i class="icon-folder-close"></i> Platforms</a>
</div>
</td>
<td>samia/Platforms group</td>
</tr>
<tr>
<td>
<div style="white-space: nowrap">
<a href="/samia/LargeSml"><i class="icon-folder-close"></i> LargeSml</a>
</div>
</td>
<td>samia/LargeSml group</td>
</tr>
<tr>
<td>
<div style="white-space: nowrap">
<a href="/samia/Processes"><i class="icon-folder-close"></i> Processes</a>
</div>
</td>
<td>samia/Processes group</td>
</tr>
<tr>
<td>
<div style="white-space: nowrap">
<a href="/samia/Tills"><i class="icon-folder-close"></i> Tills</a>
</div>
</td>
<td>Tills für samia</td>
</tr>
</table>

首先，我要查看/顯示：導出鏈接平台LargeSml

其次，我想進入Export並搜索更多標簽，等等。

到目前為止，我有以下代碼，但似乎無法正常工作。

Document doc = Jsoup.connect("http://************").cookies(loginCookies).get();


            for (Element table : doc.select("groups_list")) {
                for (Element row : table.select("tr")) {
                    Elements tds = row.select("td");

                    System.out.println(tds.get(0).text());
                }
            }

這是我的第二種方法。 在頁面上，我想瀏覽表groups_list的標簽“導出”，“鏈接”，“平台”等。因此，如果在這些子頁面下（例如“導出”），我將搜索所有以Doc結尾的鏈接。 這些都是在javascript中。 后面是腳本。

      <script>
    var data = {"totalRecords": 2, "sort": "name", "startIndex": 0, "dir": "asc", "records": [{"raw_name": "samia/export/Citydata", "last_changeset": "\n  <div>\n      <pre><a title=\"xn00761:\n\nAdded tag V2.11.d50.mkt.001 for changeset 56e10a4864ff\" class=\"tooltip\" href=\"/samia/export/Citydata/changeset/f602409eba261d749d23dc75551b2959425dfa8d\">r17:f602409eba26</a></pre>\n  </div>\n", "atom": "\n    <a title=\"Subscribe to samia/export/Citydata atom feed\" href=\"/samia/export/Citydata/feed/atom?api_key=e214ebea2335318bee1460a1fd33725ab3e1002e\"><i class=\"icon-rss-sign\"  style=\"color: #fa9b39\"></i></a>\n", "owner": "owner", "rss": "\n    <a title=\"Subscribe to samia/export/Citydata rss feed\" href=\"/samia/export/Citydata/feed/rss?api_key=e214ebea2335318bee1460a1fd33725ab3e1002e\"><i class=\"icon-rss-sign\" style=\"color: #fa9b39\"></i></a>\n", "name": "\n    \n  <div style=\"white-space: nowrap;

    var myDataSource = new YAHOO.util.DataSource(data);
    myDataSource.responseType = YAHOO.util.DataSource.TYPE_JSON;

然后，當我瀏覽所有這些... Doc鏈接時，我想看看是否還有更多帶有特定標簽的鏈接。 在下面您會看到，我想瀏覽標記名稱“ r0：9ed1679c7a35”內的所有鏈接

<div class="box" style="margin-top: -20px">
<div class="title">
    <div class="breadcrumbs">
        <a href="/samia/Export/CitydataDoc/changelog">Latest changes</a>
    </div>
</div>
<div class="table">
    <div id="shortlog_data">
        <table class="table_disp">

    <th class="left">Revision</th>
    <th class="left">Commit message</th>

<tr class="parity0">
    <td>
      <div>
        <div class="changeset-status-container">

        <pre><a href="/samia/Export/CitydataDoc/files/9ed1679c7a35b76e1402b540cee38000461fdfdd/">r0:9ed1679c7a35</a></pre>
     </div>
    </td>
    <td>

    </td>
    <td><span class="tooltip" title="Fri, 25 Apr 2014 11:03:45">

    </td>
    <td title="owner;">owner</td>
    <td>
         <div class="tagtag" title="Tag tip">
             <a href="/samia/Export/CitydataDoc/files/9ed1679c7a35b76e1402b540cee38000461fdfdd/">tip</a>

         <div class="branchtag" title="Branch default">
             <a href="/samia/Export/CitydataDoc/changelog?branch=default">default</a>
         </div>
    </td>
</tr>

當我在一個名為“ r0：9ed1679c7a35”的鏈接下時，我具有以下HTML代碼。 在這里，我想瀏覽Changedokumentation.docx。

<div class="browser-body">
    <table class="code-browser">
        <thead>
            <tr>
                <th>Name</th>

                <th>Mimetype</th>
                <th>Last Revision</th>
                <th>Last modified</th>
                <th>Last committer</th>
            </tr>
        </thead>

                 </td>
                 <td>

                 </td>
                 <td>
                      application/vnd.openxmlformats-officedocument.wordprocessingml.document
                 </td>
                 <td>
                         <div class="tooltip" title="Changedokumentation">
                          <pre>r0:9ed1679c7a35</pre>
                         </div>
                 </td>
                 <td>
                         <span class="tooltip" title="Fri, 25 Apr 2014 11:03:45">

                 </td>
            </tr>
        </tbody>
        <tbody id="tbody_filtered" style="display:none">
        </tbody>
    </table>
</div>

最后，當我到達“結束頁面”時，我希望首先列出名稱（因此我知道此文件已存在），並且還可以選擇下載文件。 當按下“下載為原始文件”時，我可以下載它。 這是在代碼中。

<div id="body" class="codeblock">

       </div>
</div>

我知道那是太多的代碼。 但這很容易理解，我希望:-)

Answer 1

您在JSOUP中使用css之類的選擇器 。 使用它的方式，它會搜索一個名為groups_list的元素標簽，當然找不到。 相反，您需要查找ID為groups_list的table 。 我認為這可以做到：

doc.select("table#groups_list")

將其放在外部循環中，至少應打印出td元素。

由於在html文檔中，該id應該是唯一的，因此您還可以執行以下操作：

doc.select("#groups_list")

要么

doc.select("table[id=groups_list]")

最后，如果您不想使用JSOUP的css select引擎，則可以使用JSOUP方法通過id直接訪問元素：

doc.getElementById("groups_list");
