Regexp

Hello!

Anyone who can help me with this. If i have a string and want to take
out a sub string of that by regexp.

1. string = "Today is it monday after work. blah blah."
or
2. string2 = "monday morning. Nice day today."

And i would like to get a certain line with the word monday in it.
Like results below.

1. result = "Today is it monday after work"
2. result2 = "monday morning"

Thanks
Svea

simple, but for sure not perfect:

/(?:.*?\.)*(.*?monday.*?)\./.match(<your string>)[1]

e.g.:
/(?:.*?\.)*(.*?monday.*?)\./.match('asdasd . asdas dasd .it is monday
morning. hello world')[1]
=> "it is monday morning"

Regards
Clemens

So you want the sentence, not including the period? What if there is a
preceding sentence?

Try
puts string[/[^.]*[Mm]onday[^.]*/]

Thanks for the fast reply.
Works nice for stripping the last part but not the first.
I get the lines before also.

/(?:.*?\.)*(.*?monday.*?)\./.match('asdasd . asdas dasd .it is monday
morning. hello world')
=> asdasd . asdas dasd .it is monday morning.

e.g.:
/(?:.*?\.)*(.*?monday.*?)\./.match('asdasd . asdas dasd .it is monday
morning. hello world')[1]
=> "it is monday morning"
