如何在没有HTML包装的情况下保存DOMDocument的HTML？
$postarray['post_content'] = $d->saveXML($d->getElementsByTagName('p')->item(0));<p>If you like</p>
function rseo_decorate_keyword($postarray) {
global $post;
$keyword = "Jasmine Tea"
$content = "If you like <h1>jasmine tea</h1> you will really like it with Jasmine Tea flavors.
This is the last ocurrence of the phrase jasmine tea within the content. If there are other instances of the
keyword jasmine tea within the text what happens to jasmine tea."
$d = new DOMDocument();
@$d->loadHTML($content);
$x = new DOMXpath($d);
$count = $x->evaluate("count(//text()[contains(translate(., 'ABCDEFGHJIKLMNOPQRSTUVWXYZ', 'abcdefghjiklmnopqrstuvwxyz'),
'$keyword') and (ancestor::b or ancestor::strong)])");
if ($count > 0) return $postarray;
$nodes = $x->query("//text()[contains(translate(., 'ABCDEFGHJIKLMNOPQRSTUVWXYZ', 'abcdefghjiklmnopqrstuvwxyz'), '$keyword')
and not(ancestor::h1) and not(ancestor::h2) and not(ancestor::h3) and not(ancestor::h4) and not(ancestor::h5) and not(ancestor::h6)
and not(ancestor::b) and not(ancestor::strong)]");
if ($nodes && $nodes->length) {
$node = $nodes->item(0);
// Split just before the keyword
$keynode = $node->splitText(strpos($node->textContent, $keyword));
// Split after the keyword
$node->nextSibling->splitText(strlen($keyword));
// Replace keyword with <b>keyword</b>
$replacement = $d->createElement('strong', $keynode->textContent);
$keynode->parentNode->replaceChild($replacement, $keynode);

所有这些答案现在都是不对，因为PHP 5.4和Libxml 2.6loadHTML现在有一个$option参数，该参数指示Libxml如何解析内容。因此，如果我们使用以下选项加载HTML$html->loadHTML($content, LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD);做时saveHTML()不会有doctype，不<html>，而不是<body>.LIBXML_HTML_NOIMPLIED关闭隐含html/body元素的自动添加LIBXML_HTML_NODEFDTD防止在找不到默认的doctype时添加。关于Libxml参数的完整文档是这里(请注意，loadHTMLDocs说Libxml 2.6是必需的，但是LIBXML_HTML_NODEFDTD仅在Libxml 2.7.8和LIBXML_HTML_NOIMPLIED见Libxml 2.7.7) -

只需在加载了loadHTML()文档后直接删除节点：# remove <!DOCTYPE $doc->removeChild($doc->doctype); # remove <html><body></body></html> $doc->replaceChild($doc->firstChild->firstChild->firstChild, $doc->firstChild);
