Backport #6307: REXML parser does not parse valid XML (The 'xml' prefix must not be bound to any other namespace)

• Status: Closed
• Assignee: naruse (Yui NARUSE)

[studnev (Aleksey Studnev)]

Attached is an example file which is not parsed by REXML parser, generating an error:

The 'xml' prefix must not be bound to any other namespace (http://www.w3.org/TR/REC-xml-names/#ns-decl)

The problem is in these following lines:

            attrs.each { |a,b,c,d,e| 
              if b == "xmlns"
                if c == "xml"
                  if d != "http://www.w3.org/XML/1998/namespace"
                    msg = "The 'xml' prefix must not be bound to any other namespace "+
                    "(http://www.w3.org/TR/REC-xml-names/#ns-decl)"
                    raise REXML::ParseException.new( msg, @source, self )

There is a description of this problem also in: https://rails.lighthouseapp.com/projects/8994/tickets/3701-bug-in-baseparserrb
