Description:
------------
XSLT instruction comment() doesn't work when libxslt is used. But when I've replaced php extension php_domxml.dll by old version (from php 4.3.2) all was worked.

Reproduce code:
---------------
$xml = '<?xml version="1.0"?>
<root>
	<A>
		<!-- COMMENT 1 //-->
	</A>
</root>
';

$xslt = '
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="xml" encoding="windows-1251"/>
<xsl:template match="@*|node()|comment()">
	<xsl:copy><xsl:apply-templates select="@*|node()|comment()" /></xsl:copy>
</xsl:template>
</xsl:stylesheet>
';

$xml_obj = domxml_open_mem ($xml);
$xslt_obj = domxml_xslt_stylesheet ($xslt);
$result_obj = $xslt_obj->process ($xml_obj);
$result = $xslt_obj->result_dump_mem ($result_obj);
echo htmlspecialchars ($result);

Expected result:
----------------
<?xml version="1.0" encoding="windows-1251"?> <root> <A> <!-- COMMENT 1 //--> </A> </root> 

Actual result:
--------------
<?xml version="1.0" encoding="windows-1251"?> <root> <A> </A> </root>

Can you send a link to your phpinfo output? as I can't reproduce this

Hello.
This note was sent to wrong section (for ALL user). May be you'll receive it twice.

There is a new info: it works properly in CGI mode but incorrectly in API mode (I use Apache 1.3.27).

phpinfo reference:
http://www.aesthetic.com.ua/misc/phpinfo.htm
Sorry for some skipped info - this was done by demand of our system administrator.

Furthermore if I remove comment() instruction from XSTL template the result in CGI mode is correct!

The part of XSLT template:
<xsl:template match="@*|node()">
  <xsl:copy><xsl:apply-templates select="@*|node()"/>
</xsl:copy>

The result:
<?xml version="1.0" encoding="windows-1251"?> <root> <A> <!-- COMMENT 1 //--> </A> </root>

Try disabling the Zend Optimizer first..

Trying...
It has no effect.

Please try using this CVS snapshot:

  http://snaps.php.net/php4-STABLE-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php4-win32-STABLE-latest.zip

And make sure you first remove ALL old php dlls before installing the snapshot.

There are no changes. :-(( What do I wrong? All dll's were deleted first. Then I unpacked files into php dir and restarted web server.

Tested with latest CVS myself on Windows and could not reproduce with the provided example script.

Make sure you REALLY replaced ALL the related DLLs. INCLUDING the libxslt.dll and libxml2.dll and iconv.dll..
 [2003-12-03 11:26 UTC] apetrenko at tmsoft-ltd dot kiev dot ua 
The files libxslt.dll and libxml2.dll are not present in package php4-win32-STABLE-latest.zip (downloaded 01.12.2003). Moreover I can't find them on my hard disk...
