在PHPDOMXPath中，我想用html标记和文本获取我的完整页脚

我想用domxpath获取包含所有html标记和文本的页脚。 html:

---

您可以只针对父页脚，然后迭代子页脚，然后使用

->saveHTML（）

并将它们不断添加到字符串容器中：

$dom = new DOMDocument('1.0');
$dom->loadHTML($input);
$xpath = new DOMXPath($dom);
$tags = $xpath->query('//div[contains(@class,"footer")]');

$innerHTML = '';
if($tags->length > 0) { // if found
    foreach($tags->item(0)->childNodes as $c) {
        $innerHTML .= $dom->saveHTML($c);
    }
}

echo $innerHTML;

---

这正是我想要的：）谢谢alot@user3696557当然，我很高兴这有帮助

  $dom = new DOMDocument('1.0');
  $dom->loadHTML($input);
  $xpath = new DOMXPath($dom);
  $tags=$xpath->query('//div[contains(@class,"footer")]');

foreach ($tags as $tag) {
  $innerHTML = '';

$children = $tag->childNodes;
foreach ($children as $child) {
    $tmp_doc = new DOMDocument();
    $tmp_doc->appendChild($tmp_doc->importNode($child,true));        
    $innerHTML .= $tmp_doc->saveHTML();
  }

 }

$dom = new DOMDocument('1.0');
$dom->loadHTML($input);
$xpath = new DOMXPath($dom);
$tags = $xpath->query('//div[contains(@class,"footer")]');

$innerHTML = '';
if($tags->length > 0) { // if found
    foreach($tags->item(0)->childNodes as $c) {
        $innerHTML .= $dom->saveHTML($c);
    }
}

echo $innerHTML;
