problem with DOMDocument

hi I have trouble while creating an DOMDocument. When I make $test = new DomDocument('1.0'); php tells me a warning error like: Entity: line 1: parser error : Start tag expected, '&lt;' not found ... Because of unknow reasons the DomDocument constructor expected a tag like '<test />'. Ive looked in the manual and see DomDocument::__construct([ string $version [, string $encoding ]] ); btw when I type $test = new DomDocument('<test />'); then comes no warning error. Why can I not create a dom document like $test = new DomDocument('1.0'); without any warning error? I can suppress the warning with @. When I make var_dump on $test it comes object(domdocument)#1 (0) { } that means the object is created. I use XAMPP with PHP 5.2.6 on an windows vista machine thanks for any help
