SimpleXML addChild() namespace problem

This is problematic code, even though it works, because it auto-generates an unnecessary xmlns: attribute: $item->addChild('itunes:subtitle', $mySubTitle,"itunes"); It generates the following XML: <itunes:subtitle xmlns:itunes="itunes">Musical Mockery</itunes:subtitle> When really all we want is this: <itunes:subtitle>Musical Mockery</itunes:subtitle> Furthermore, dumping it into a DomDocument and attempting to use removeAttributeNS() to remove the spurious attribute removes the entire kit and kaboodle, leaving only: <subtitle>Musical Mockery</subtitle> How can one get the desired result, short of using a regexp? (I have done this, and it works, but is a silly hack because it doesn't use XML parsing to address an XML problem). Thanks, Carole
