Hi
The workaround of inserting an empty text node manually after element creation
still seems to work, but inserting a text node is what the $value param in
createElement($name,$value) is surely for?
i.e.
$script = $doc-createElement ('script', '') //not working in 5.5
is the same thing as:
$script = $doc-createElement ('script');
$script-appendChild ($doc-createTextNode ('')); //does work in 5.5
On setting, this creates a Text node with the unparsed contents of the string

The behaviour you describe is pretty valid for XML. saveHTML() method should be
used if you need a HTML conform output. Also the behavior is different in 5.4
when using loadXML (tested with your snippet). PHP 5.5 uses libxml 2.9.1 where
5.4
uses libxml 2.7.8. libxml supports HTML 4.0 parser only AFAIR (yet at least).
You might be also interested in workarounds suggested by users

Description:
There is a regression in PHP5.5RC where empty text nodes seem to be lost e.g.
script src=/script is turned into script src=/
This breaks XHTML pages because browsers don't recognise the self-closing
syntax.
In PHP 5.3 and 5.4 the two calls below had different output
$doc-createElement('script') output script/
$doc-createElement('script', '') output script/script
In PHP5.5, they both output script/ only. Documents parsed using loadXML
suffer this too - script/script loses the inner text node and is
transformed into script/.
Test script:
---
?php
error_reporting(E_ALL | E_STRICT);
ini_set('display_errors', 1);
$doc = new DOMDocument;
$script = $doc-createElement('script', '');
$script-setAttribute('src', 'foo.js');
$doc-appendChild($script);
echo $doc-saveXML();
$doc-loadXML('script src=abc.js/script');
echo $doc-saveXML();
Expected result:
?xml version=1.0?
script src=foo.js/script
?xml version=1.0?
script src=foo.js/script
Actual result:
--
?xml version=1.0?
script src=foo.js/
?xml version=1.0?
script src=foo.js/
