我想使用DOM Document获取整个body标签内容.
我使用以下代码:
$dom = new domDocument;
/*** load the html into the object ***/
$dom->loadHTML($html);
/*** the table by its tag name ***/
$tables = $dom->getElementsByTagName('body')->item(0)->nodeValue;
这给了我TExt.我想要全身内容.

您可以将正文DOMElement传递给DOMDocument :: saveHTML()或DOMDocument :: saveHTMLFile(),例如
<?php
$doc = new DOMDocument;
$doc->loadhtmlfile('http://stackoverflow.com');
$body = $doc->getElementsByTagName('body');
if ( $body && 0<$body->length ) {
$body = $body->item(0);
echo $doc->savehtml($body);
}
