DOMXPath匹配文本

Question

代码示例：

＆＃13;

＆＃13;

$html = <<<END
  <tr>
    <td>Text-1</td>
  </tr>

  <tr>
    <td>Blah 1</td>
    <td>Blah 2</td>
    <td>Blah 3</td>
    <td>Blah 4</td>
  </tr>

  <tr>
    <td>Text-2</td>
  </tr>

  <tr>
    <td>Blah 1</td>
    <td>Blah 2</td>
    <td>Blah 3</td>
    <td>Blah 4</td>
  </tr>
END;

$dom = new DOMDocument(); 
$dom->preserveWhiteSpace = false;
$dom->loadhtml($html);
$xpath = new DOMXPath($dom);

   // Grab the text
$nodes = $xpath->query('//td[contains(text(), "Text-2")]|//td[contains(text(), "Blah 1")]/following-sibling::td');

echo $nodes->item(0)->textContent;

＆＃13;

＆＃13;

＆＃13;

我试图在Text-2下抓住Blah 2，问题是在Text-1下抓住了Blah 2

Answer 1

首先，找到<tr>孩子<td>的{​​{1}}，然后遍历下一个兄弟，直到找到"Text-2" <td> "Blah 1" 。答案就是下一个兄弟姐妹。

//tr[contains(td/text(), "Text-2")]/following-sibling::tr/td[contains(text(), "Blah 1")]/following-sibling::td'

Answer 2

找到答案：

//*[text()='Text-2']/following::td[text()='Blah 1']/following-sibling::td
