When I have text exported from MS Word to HTML where is "<?xml:namespace..." (see $string) and I want strip tags from it, I get text before it only.

example:
<?

$string = <<<EOD
<BODY><P class=MsoNormal><B><U>I am hungry<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /></U></B></P> <P class=MsoNormal>I am really hungry<o:p></o:p></SPAN></BODY>  
EOD;

var_dump(strip_tags($string));

?>

output is:

string(11) "I am hungry"

This markup is not XHTML 1.0 compliant, from my readying.
That is, I'm pretty sure <?xml ...> must be the first line
of the document.

This, however, is not the reason why strip_tags is failing.
It is failing because it recognises '<?' (from <?xml ) as
the beginning of PHP code - not xml. This presents problems
with applying strip_tags to xhtml. The reason why this
probably hasn't been picked up is that correct (??) XML
declarations are of the form <?xml ... ?> - which should
not contain anything to be out put anyway.

If you/anyone can show that this is valid we can work
around it (by demoting the PHP strip_tags state to an HTML state).

It is done by MS Word and I can?t affect it.
Although it isn't compliant, I think, that is a bug. Fnc strip_tags() has strip all tags anywhere inside the string. 
I can't check, if all tags in the string are valid.
If you want to show if this is valid, I would have to call to Redmond :-)

Latest CVS now checks if <? is followed by 'xml'. If so,
it treats it just like HTML.

Check latest CVS to confirm that this works (www.php.net/downloads.php)

erm, why does strip_tags() allow PHP tags in the first place? this doesn't look right.. (am I missing something?)
