不会更改标签的 Java html 解析器

Question

我目前正在使用 Jsoup 解析器接收一些 HTML，然后更改特定标签的一些标题。问题是我的 html 出于某种原因在通过 jsoup 解析器时似乎被更改了。有没有办法告诉 jsoup 不要附加任何 html.body 标签，或者不要添加丢失的标签？

它似乎在改变我的表格。

原创

 <div class="mstrPanelPortrait">
         <table cellpadding="0" class="pane" cellspacing="0">
            <tr>
               <td>
                  <table class="pane" cellspacing="0">
                     <tr>
                        <td class="mstrPanelBody" sty="body">
                           <div>
                              <div class="mstrBrowser">

通过jsoup后

 <div class="mstrPanelPortrait" title="darrensTest">
         <table cellpadding="0" class="pane" cellspacing="0">
            <tbody>
               <tr>
                  <td>
                     <table class="pane" cellspacing="0">
                        <tbody>
                           <tr>
                              <td class="mstrPanelBody" sty="body">

您可以看到在几个地方添加了 tbody。不知道为什么

整个html

Answer 1

据我所知，没有办法告诉 Jsoup 不平衡标签。

您可以改用非默认 XML 解析器，它不会添加任何新标签(例如 tbody)，但只会平衡尚未平衡的标签。

那么，如果 Jsoup 不添加任何标签，而只是平衡 HTML 是否可以？

如果该问题的答案是肯定的，那么您应该使用 XML 解析器而不是默认的 HTML 解析器。

doc = Jsoup.parse(html, "", Parser.xmlParser());

这将解析 HTML 但会添加结束标记，但不会添加不存在的标记，因此不会更改结构。然后，您可以以正常的 Jsoup 方式从文档中进行选择。

    <table class="pane" cellspacing="0">

      <td class="mstrPanelBody" sty="body">
