DOMXPath匹配文本

Question

代码示例：

 $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; 

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

Answer 1

首先，找到<tr>具有带有"Text-2"的<td>子项，然后遍历下一个兄弟，直到找到具有"Blah 1"的<td> 。 答案是下一个兄弟姐妹。

//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
