Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

When using xml.el to parse some XML, I encountered a small bug in
its handling off tag attributes. Specifically, it doesn't allow
for the empty string as an attribute value, whereas the XML
standard pretty clearly allows for the empty string.

In a fresh emacs -q --no-site-file, the following steps should
reproduce the faulty behavior: Load the xml.el library. Insert
"<foo bar=''/>" into the buffer, and xml-parse-region it.

The reason for this misbehavior appears to be the regular
expressions appearing on lines 292 and 293 of xml.el. I think a
simple change of the +'s to *'s should fix them.
