我遇到了 appendXML() 的问题，它不会将表单附加到 HTML。现在我有这个代码$domdocument = new DOMDocument();$domdocument->loadHTML($html);$domlookup = new DOMXPath($domdocument);$formDivs = $domlookup->query("//*[contains(@class, 'formClass')]");$frag = $domdocument->createDocumentFragment();$frag->appendXML($formHTML);for ($i = $formDivs->length - 1; $i > -1; $i--) { $formDivs->item($i)->parentNode->appendChild($frag);}@$html = $domdocument->saveHTML();该代码运行良好，并使用“formCLass”类简单的 HTML 附加到 div，如文本和带有文本的 div。但是，当涉及到附加表单时……嗯……那是另一回事。我也尝试过使用$frag->nodeValue = $formHTML;代替$frag->appendXML($formHTML);但它仍然没有工作......试$frag->textContent = $formHTML;会将表单输出为文本，显然这对我不起作用。我怎么解决这个问题？表格代码：<form method="post"><div class="fb-text form-group field-petname"><label for="petname" class="fb-text-label">"Pet Name"<span class="fb-required">*</span></label><input type="text" placeholder="Your Pet Name" required = "required" aria-required = "true" class="form-control" name="petname" id="petname"></div><div class="fb-text form-group field-petowner"><label for="petowner" class="fb-text-label">"Pet owner"<span class="fb-required">*</span></label><input type="text" placeholder="Insert owner's name" required = "required" aria-required = "true" class="form-control" name="petowner" id="petowner"></div><div class="fb-text form-group field-phone"><label for="phone" class="fb-text-label">"Phone number"<span class="fb-required">*</span></label><input type="text" placeholder="Phone number" required = "required" aria-required = "true" class="form-control" name="phone" id="phone"></div><div><div id="goldenmembership"><i class="fas fa-truck"></i>Free delivery!</div></div><div class="fb-select form-group field-brand"><label for="brand" class="fb-select-label">What brand would your pet like?<span class="fb-required">*</span></label>

我刚刚使用您的代码和我自己的一些 HTML 组合了一个非常简单的测试用例，它似乎可以附加，如下所示。
您的表单的 HTML 是否有可能无效？
如果您仍然遇到问题，您能否在某处发布您的 HTML，以便我们可以尝试一下，好吗？
$html = <<<HTML
<html>
<body>
<div class="formClass">
<!-- Placeholder -->
</div>
</body>
</html>
HTML;
$formHtml = <<<HTML
<form action="#" method="post">
<input type="text" id="test"/>
</form>
HTML;
$domdocument = new DOMDocument();
$domdocument->loadHTML($html);
$domlookup = new DOMXPath($domdocument);
$formDivs = $domlookup->query("//*[contains(@class, 'formClass')]");
$frag = $domdocument->createDocumentFragment();
$frag->appendXML($formHtml);
for ($i = $formDivs->length - 1; $i > -1; $i--) {
$formDivs->item($i)->parentNode->appendChild($frag);
}
$html = $domdocument->saveHTML();
echo $html;
HTML 输出：
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
<html>
<body>
<div class="formClass">
<!-- Placeholder -->
</div>
<form action="#" method="post">
<input type="text" id="test">
</form></body>
</html>
