As well as any substring "registrantName>". And well-formed XML won't
guarantee that only "<registrantName>" and "</registrantName>" will
contain that.

gsub!(/(<\/?)registrantName>/, '\1SUB.HEAD4>') should do.

But again, CDATA-sections and comments may well contain these strings.
I'd use XSLT or some SAX-Library if it has to be ruby.
