我有一個包含多個標簽的字符串。我想獲取所有內容并將它們連接到一個有效的結構。例如：<html><body><div>Content</div></body></html><html><body><div>Content</div></body></html><html><body><div>Content</div></body></html><html><body><div>Content</div></body></html>應該是：<html> <body> <div>Content</div> <div>Content</div> <div>Content</div> </body></html>我當前的代碼如下所示： libxml_use_internal_errors(true); $newDom = new DOMDocument(); $newBody = ""; $newDom->loadHTML(mb_convert_encoding($html, 'HTML-ENTITIES', 'UTF-8')); $bodyTags = $newDom->getElementsByTagName("body"); foreach($bodyTags as $body) { $newBody .= $newDom->saveHTML($body); }$newBody現在包含所有正文標簽：<body><div>Content</div></body><body><div>Content</div></body><body><div>Content</div></body>如何只保存每個正文標簽的HTML內容？$newBody編輯：基于@NigelRen的答案，這是我的解決方案： libxml_use_internal_errors(true); $newDom = new DOMDocument(); $newBody = ''; $newDom->loadHTML(mb_convert_encoding($html, 'HTML-ENTITIES', 'UTF-8')); $bodyTags = $newDom->getElementsByTagName("body"); foreach($bodyTags as $body) { foreach ($body->childNodes as $node) { $newBody .= $newDom->saveHTML($node); } } $newDom = new DOMDocument(); $newDom->loadHTML(mb_convert_encoding($newBody, 'HTML-ENTITIES', 'UTF-8')); $newBody = $newDom->saveHTML();

這很尷尬，因為當您使用它時，它將嘗試修復原始文檔中的HTML。這創建了一個結構，它不是你所認為的。loadHTML()
但是，如果您有文檔的基本大綱，則以下內容會將標記的內容復制到新文檔（代碼中的注釋）...<body>
$html = '<html><body><div>Content1</div></body></html>
<html><body><div>Content2</div></body></html>
<html><body><div>Content3</div></body></html>';
libxml_use_internal_errors(true);
$newDom = new DOMDocument();
// New document with final code
$newBody = new DOMDocument();
$newDom->loadHTML(mb_convert_encoding($html, 'HTML-ENTITIES', 'UTF-8'));
// Set up basic template for new doucument
$newBody->loadHTML("<html><body /></html>");
// Find where to add any new content
$addBody = $newBody->getElementsByTagName("body")[0];
// Find the existing content to add
$bodyTags = $newDom->getElementsByTagName("body");
foreach($bodyTags as $body) {
// Add all of the contents of the <body> tag into the new document
foreach ( $body->childNodes as $node ) {
// Import the node to copy to the new document and add it in
$addBody->appendChild($newBody->importNode($node, true));
}
}
echo $newBody->saveHTML();
這給了...
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
<html><body><div>Content1</div><div>Content2</div><div>Content3</div></body></html>
限制是不會保留標記之外的任何內容和標記的任何屬性。<body><body>
