Hi there,
Trying for a couple of hours (again without success) to create a regular
expression that matches a multi-line statement , i found myself here
again, asking for help.
The case is now:
/123/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxx
I am unable to match the statements that contains multiple lines.
The regexp looks so far like this:
/(<[a-z][a-z][a-z]>.*?$)/m
The question is why is only returning matches until the first end of
line?
I am sure the greediness of the expression should take him to the last
new line character just before the next statement comes, but maybe is
just that i need to read a lot more to understand the concept right.
In any case, can somebody point me what i am missing to run the scan
method and get each match (including the ones with multiple lines)?
Thanks a lot.

In multiline regular expressions in Ruby, the caret and dollar sign
also match newlines in the string, which is why it only read a line at
a time.

Hi, Guillermo, your regexp works for me. Perhaps you are using a method
that
only looks for the first match.
str = “/123/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxx”
results = str.scan( /(<[a-z][a-z][a-z]>.*?$)/m )
require ‘pp’
pp results
>> [["/123/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"],
>> [“xxxxx”],
>>
[“xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx”],
>>
[“xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx”]]
