It matters for XML documents, so, yes, any XML parser will definitely honour the document order (which is actually well defined for an XML document). What you might be referring to is the case of a specific XML document format, where the application (or sometimes specification) can explicitly state that the element order in a given subtree has no meaning for the semantics of the element and that therefore code must ignore the order in which elements occur. But that won't magically make the parser ignore it for you. That's a totally different level of abstraction and a deliberate decision of the code that *uses* the parser.
