Description:
------------
Using the example for LoadHTML the www.php.net site contains a URL with an ampersand (line 118 <a href="http://cvs.php.net/diff.php/php-src/NEWS?login=2&r1=1.1247.2.452&r2=1.1247.2.522">NEWS</a> file.).  The error says it is looking for a missing ";", apparently thinking it should be an entity.

When I remove the try/catch, no errors occur, but nothing gets printed.  Using a different URL to a file without the & works correctly.

Reproduce code:
---------------
<?php
try
{
    $dom = new domdocument;
    @$dom->loadHTMLFile("http://www.php.net/");
    $xp = new domxpath($dom);
    $result = $xp->query("/html/head/title");
    print $result[0]->firstChild->data;
}
catch (exception $exc)
{
    print $exc->getMessage()." at line ".$exc->getLine();
}

?>

Expected result:
----------------
PHP: Hypertext Preprocessor

Actual result:
--------------
<?php
try
{
    $dom = new domdocument;
    @$dom->loadHTMLFile("http://www.php.net/");
    $xp = new domxpath($dom);
    $result = $xp->query("/html/head/title");
    print $result[0]->firstChild->data;
}
catch (exception $exc)
{
    print $exc->getMessage()." at line ".$exc->getLine();
}

?>

Sorry...  Wrong copy/paste for the actual result...

ERROR [2]domdocument::loadHTMLFile() [<a href='function.loadHTMLFile'>function.loadHTMLFile</a>]: htmlParseEntityRef: expecting ';' in http://www.php.net/, line: 118. PHP 5.0.0RC1-dev (WINNT).  at line 5

Please try using this CVS snapshot:

  http://snaps.php.net/php5-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php5-win32-latest.zip

If you encounter the error with a current snap, can you provide the results of:
<?php
  var_dump(stream_get_wrappers());
?>

Reran using PHP5 version available as of January 16, 2004, 8:05:07 AM East Coast Time, USA.  Results with the addition of the var_dump(stream_get_wrappers()); in the catch block:

<b>Exception encountered</b><br>ERROR [2]domdocument::loadHTMLFile() [<a href='function.loadHTMLFile'>function.loadHTMLFile</a>]: htmlParseEntityRef: expecting ';' in http://www.php.net/, line: 118. PHP 5.0.0RC1-dev (WINNT).  at line 5array(5) {

Hope this helps...  Let me know if I can provide more info....

Can you remove the try/catch block as well as not surpress the errors. Could you email me the errors as I believe you will have quite a few.

XPath queries have changed from returning arrays to returning node-lists....

@ suppression of libxml is still required, which is correct behavior for PHP5.
