排除某些特定元素的 xpath [英] xpath that exclude some specific elements

问题描述

这是我要分析的页面 HTML 的简单版本:

This is a simple version of the HTML of the page that I want analyse:

<table class="class_1">
  <tbody>
    <tr class="class_2">
      <td class="class_3">&nbsp;</td>
      <td class="class_4">&nbsp;</td>
      <td class="class_5">&nbsp;</td>
    </tr>
    <tr class="class_2">
      <td class="class_3">&nbsp;</td>
      <td class="class_4">&nbsp;</td>
      <td class="class_5"><span class="class_6"></span>square</td>
    </tr>
    <tr class="class_2">
      <td class="class_3">&nbsp;</td>
      <td class="class_4">&nbsp;</td>
      <td class="class_5"><span class="class_7"></span>circle</td>
    </tr>
    <tr class="class_2">
      <td class="class_3">&nbsp;</td>
      <td class="class_4">&nbsp;</td>
      <td class="class_5"><span class="class_6"></span>triangle</td>
    </tr>
  </tbody>
</table>

您可以在以下位置找到该页面https://sabbiobet.netsons.org/test.html

You can find the page at https://sabbiobet.netsons.org/test.html

如果你在谷歌表格中尝试这个功能:

If you try in a google sheets the function:

=IMPORTXML("https://sabbiobet.netsons.org/test.html";"//td[@class='class_5']")

=IMPORTXML("https://sabbiobet.netsons.org/test.html";"//td[@class='class_5']")

我会得到:

• • 方形

  我需要使用 class="class_5" 获得所有 <td> 减去那些具有   或.

  I need to obtain all the <td> with class="class_5" minus the ones that have   or <span class=class_7>.

  换句话说，我只想获得这些值:

  In other words I want to obtain only these values:

  • 方形
  • 三角形

  有人可以帮我吗?

  推荐答案

  这应该有效:

  //td[@class='class_5'][not(text()=' ')][not(./span[@class='class_7'])]
  

  其中 [not(text()=' ')] 不是测试规则空间，而是测试具有 Unicode 代码 U+00A0 的符号，您可以在 Windows 中使用 alt+0160 从键盘输入，其中数字将从小键盘输入.

  where [not(text()=' ')] is not testing for a reqular space but rather for a symbol with Unicode code U+00A0 that you can input from keyboard in windows using alt+0160 where numbers are to be input from numpad.
