Bug #12860 Updated: problem with strip_tags()

ID: 12860 Updated by: swm Reported By: costrova@prdel.cz Old Status: Open Status: Closed Bug Type: Strings related Operating System: Linux and Win PHP Version: 4.0.6 New Comment: 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) Gavin Previous Comments: ------------------------------------------------------------------------ [2001-08-21 05:50:14] costrova@prdel.cz 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 :-) ------------------------------------------------------------------------ [2001-08-20 11:02:27] swm@php.net 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). ------------------------------------------------------------------------ [2001-08-20 09:45:13] costrova@prdel.cz 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" ------------------------------------------------------------------------ Edit this bug report at http://bugs.php.net/?id=12860&edit=1
