Description:
------------
When trying to save the contents of a HTML document's body without the surrounding
<body></body> tags I had the idea of appending all of the childNodes to a
DOMDocumentFragment and then passing it as the first argument ($node) to
DOMDocument::saveHTML(). However, I discovered a bug in doing so. Saving returns
invalid markup with empty tags (<></>) surrounding the content.
I have reproduced this is both 5.4.11 (with libxml 2.7.8) and 5.5.0 (with libxml
2.7.6).
Test script:
---------------
<?php
$dom = new DOMDocument();
$frag1 = $dom->createDocumentFragment();
var_dump($dom->saveHTML($frag1));
$frag2 = $dom->createDocumentFragment();
$frag2->appendChild($dom->createElement('div'));
var_dump($dom->saveHTML($frag2));
Expected result:
----------------
string(0) ""
string(11) "<div></div>"
Actual result:
--------------
string(5) "<></>"
string(16) "<><div></div></>"

Reproduced this with latest 5.5 branch. $doc = new DOMDocument(); $frag = $doc -> createDocumentFragment(); $frag -> appendXML('yyy'); echo $doc -> saveHTML($frag); // outputs <>yyy workaround is to loop through childnodes of the domdocumentfragment and savehtml to each.
