Question

I don’t know regular expression at all. Can anybody help me with one very simple regular expression which is,

extracting ‘word:word‘ from a sentence. e.g “Java Tutorial Format:Pdf With Location:Tokyo Javascript”?

• Little modification:
  the first ‘word’ is from a list but second is anything. “word1 in [ABC, FGR, HTY]”
• guys situation demands a little more
  modification.
  The matching form can be “word11:word12 word13 .. ” till the next “word21: … ” .

things are becoming complex with sec…..i have to learn reg ex 🙁

thanks in advance.

Answer 1

You can use the regex:

\w+:\w+

Explanation:
\w – single char which is either a letter(uppercase or lowercase), digit or a _.
\w+ – one or more of above char..basically a word

so \w+:\w+
would match a pair of words separated by a colon.
