<script> tags: removing CDATA created by loadHTML

[arvgta]

I'm trying to impement the "userland workaround" described here:

https://bugs.php.net/bug.php?id=54429

with the following PHP code variation:

public function __xCDATA($i) {
 $list = $i->getElementsByTagName('script');
 foreach ($list as $script) {
  if ($script->childNodes->length && $script->firstChild->nodeType == 4) {
   $text = $this->ownerDocument->createTextNode( $script->firstChild->nodeValue);
   //$script->replaceChild($text, $script->firstChild);
  }
 } 
}

see: http://4nf.org/php/JSLikeHTMLElement.txt

If I enable the last line:

//$script->replaceChild($text, $script->firstChild);

...the function crashes

What am I doing wrong?


Thanks in advance and kind regards

I also tried this, just for debugging:

public function __xCDATA($i) {
 $list = $i->getElementsByTagName('script');
 foreach ($list as $script) {
  if ($script->childNodes->length && $script->firstChild->nodeType == 4) {
   $text = $this->ownerDocument->createTextNode(";");
   $script->replaceChild($text, $script->firstChild);
  }
 } 
}

Doesn't work either (crashes).

Any ideas?

After lots of fiddling around, this code, after the returning of SaveXML, wiped out the extra CDATA:

$string = str_replace("<![CDATA[","",$string);
$string = str_replace("]]>","",$string);

However, the "XML" code returned was distorted.

Has anyone else observed the same?
