使用PHP DomDocument时如何排除警告消息？

I'm trying to use the DomDocument class to load and analyse an HTML fragment (doesn't include the <html> and <body> tags). There is a lot of garbage left over from MS-Word when it was converted into HTML, so I'm getting warning messages such as DOMDocument::loadHTML(): Tag o:p invalid in Entity, line: 69 ddtest.d8.drush.inc:68. Here is the relevant code:

    $dom = new DOMDocument;
    //load the html into the object
    $dom->loadHTML($row->body_value);

I've tried to get rid of the warning messages by using this:

    $dom = new DOMDocument;

    //load the html into the object
    $dom->loadHTML($row->body_value, LIBXML_NOWARNING);

But it has no effect, the warning messages are still displayed. What am I doing wrong?

    You could try using the error handling of libxml like this perhaps:

    libxml_use_internal_errors( true );

$dom=new DOMDocument;
$dom->preserveWhiteSpace = false;
$dom->validateOnParse = false;
$dom->standalone=true;
$dom->strictErrorChecking=false;
$dom->substituteEntities=true;
$dom->recover=true;
$dom->formatOutput=false;
$dom->loadHTML( $row->body_value );

libxml_clear_errors();
