Hi
It would be very handy to have a back reference mechanism in the regexen
spec use by XSLT etc. Much more succinct code could be written. (unless
I miss an existing feature)
Demo
code = "foo = 'bar'"
# also works when " is used as attribute value delimiter
code =~ /([^\s=]+)(\s*)(=)(\s*)(['"])([^\5]+)(\5)/
(1..7).each do |i|
print i.to_s+': '
p eval('$'+i.to_s)
end
brings
ruby backref.rb
1: "foo"
2: " "
3: "="
4: " "
5: "'"
6: "bar"
7: "'"
A concrete Use Case
Marking up XML code listings.
XSLT: (slightly outdated)
