- xsi:nil="1"/"))

you have to escape quotes with \

Hi,

It’s not only legibility, it’s enough to calculate c[i+14]  
once as the result is every time the same.

Another suggestion:

case chaine[i+14]  
when %r{twincards\>(true|false)\</twincards},  
%q{twincards xsi:nil=“1”/} then  
…  
end

You’re closing one too many sets of parents after the “true”  
conditional. Also, in the third conditional, you need to either escape  
the inner quotes or use single quotes:

“twincards xsi:nil=“1”/”  
‘twincards xsi:nil=“1”/’

You might want to rewrite it for better legibility, too. A suggestion:

test = chaine[i + 14]  
if test == ‘twincards\>false\</twincards’ or  
test == ‘twincards\>true\</twincards’ or  
test == ‘twincards xsi:nil=“1”/’

```
 # do whatever

```

end

Right! I forgot to mention that 🙂

My gut tells me this might be slower, but probably not enough to matter.  
And I always forget about %q, that’s really the best way to quote  
something that has quotes inside it.
