PHP DOMdocument echoing problem

Output:

</div>
</body>
</html>
I do not want to add html and body tags. Also do not want to tag replaced to <lang> . And is also unnecessary.
I want to receive such content, which was at the entrance, only with modified links..
Sorry for bad english!
You are seeing at the end of each line because your HTML has Windows-style line endings CR+LF. To get rid of them, run this on it before you feed it into DOMDocument — to convert them to Unix-style line endings LF:
$content = preg_replace('/\r\n/', "\n", $content);
saveXml takes an optional parameter to allow you to specify the node to output.
$dom->saveXml($dom->documentElement->firstChild->firstChild);
This will remove the html and body tags from the output.
I guess that the <html> and <body> tags get placed in because you are using loadHTML. Try using loadXML instead.
As for <lang>, it has to be replaced because otherwise the resulting XML would not be valid. If it is causing you problems, you should change your approach a little and work with it, not against it.
