xmldocument - Is it safe to return a cloned XmlNode of a local IXmlDocument in Delphi? -


i on delphi xe2. have common function takes xml string , returns clonenode of root ixmlnode. supposed commonizing settings xmldocument. inside of function use local variable ixmldocument , call things newxmldocument , modify parse options.

is such problem occurring because local variable ixmldocument goes out of scope function ends , interface reference count mechanism freed it, ignoring whether has cloned node?
