[erlang-questions] [Patch] XMERL Attributes without whitespaces

[Eranga Udesh]

It's my mistake. The XML parser I sent is w3schools and not the W3C. The
W3C parser at http://validator.w3.org too parses the same XML I sent and
return below status.

This document was successfully checked as well-formed XML!
