What Felix is suggesting is that, if the source is valid XML, then it will
have the form
<elementName>text</elementName>
so, if you call gsub! passing a regexp matching elementName>, it should
replace both the opening and closing tags. When you tried, it didn't work
because you left the opening < in the regexp, which didn't match the closing
tag (it starts with </r, not <r). The correct call to gsub should be:
xmlfile.gsub!(/registrantName>/, 'SUB.HEAD4>')
(by the way, notice that the regexp doesn't match the starting '<', so it gets
removed from the replacement string)
I hope this helps
