note 97824 rejected from domdocument.getelementsbytagname by danbrown

Note Submitter: kjhseka at hotmail dot com ---- Hello, I'm not sure if my note is a support request, a feature request or an important observation due to lack of information. The getElementsByTagName method returns the NodeList of element nodes with the specified name. Ok, but what it returns if it doesn't find anything? What it returns if the parsed xml tag doesn't exist or if it doesn't have a value? Null? Empty string? Random value? I consider that this information is important and it should be included in the reference manual. A. Langueduc
