Hi


Lately someone gave me a task, to grep from csv file but a block of
code.
How to do it ?

for example

<tag>
2
3
4
5
</tag>


How to use grep to give me all form file wich start with <tag> and end
with </tag>

I've tried that way..

puts File.readlines(ARGV[0]).grep(/<tag> * <\/tag>/)

Please help
