Hi..!

The following code parses the same XML Structure and dumps it right away. The only difference is the 'missing' doctpye for the later one. Even though the output differs a lot ;)

I'm not exactly sure if this is a php or more a libxml bug. It used to work on php 4.3.1 with LibXML2 2.4.19, wheras it does not on 4.3.2 with libxml2 2.5.x

<?PHP

 $xml=<<<EOF
<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
 <body>
  some markup...
  <script>//<![CDATA[ .. some js code ]]></script>
  some more markup
 </body>
</html>
EOF;

 $dom=domxml_open_mem($xml);
 echo $dom->dump_mem(true, 'UTF-8');

 $xml2=<<<EOF
<?xml version="1.0" encoding="iso-8859-1"?>
<html xmlns="http://www.w3.org/1999/xhtml">
 <body>
  some markup...
  <script>//<![CDATA[ .. some js code ]]></script>
  some more markup
 </body>
</html>
EOF;

 $dom=domxml_open_mem($xml2);
 echo $dom->dump_mem(true, 'UTF-8');


?>

Forgot to mention what is actually 'wrong' :>

The // in the script block gets wrapped - <![CDATA[//]]> - which is not an expected (automated) behavior and wrong.
 [2003-06-05 11:56 UTC] theseer@php.net 
Just cross-checked with the DTD for XHTML 1.0 Trans:

<!-- style info, which may include CDATA sections -->
<!ELEMENT style (#PCDATA)>
<!ATTLIST style
  %i18n;
  id          ID             #IMPLIED
  type        %ContentType;  #REQUIRED
  media       %MediaDesc;    #IMPLIED
  title       %Text;         #IMPLIED
  xml:space   (preserve)     #FIXED 'preserve'
  >

The <script> MAY have a CDATA but it's not required to. Thus the automatic addtion is a bug. ( imho )

<!-- script statements, which may include CDATA sections -->

  charset     %Charset;      #IMPLIED
  type        %ContentType;  #REQUIRED
  language    CDATA          #IMPLIED
