Not that regular expression matching is the best for parsing XML, but
for this simple task something like this would work:

require 'rex_pcre'
text = rex_pcre.match('<myMarker>captureMe</myMarker>',
[[<[^>]+>(.+)</[^>]+>]])
print(text)

I normally use [[]] around rex_pcre patterns because they (unlike the
Lua patterns) tend to have lots of \ in them you would have to quote in
regular strings.
