Regular Expressions AND

Question

I am really not good with regular expressions and I come here for some assistance :). I am trying to combine regular expressions with something like AND. For example if we have a text file with:

abc1-xyz

abc1-ertxyz

abc1xyz

postxyz

abc1

I would like to match everything that starts with "abc1" AND also contains the letters "xyz" somewhere.

I know that I can start with:

/^abc1/

but I am not sure how to combine so it can also match to contain "xyz".

Thank you for your assistance in advance.

What is the programming language? Note that you can use something like `^abc1.*xyz`, or `(?s)^abc1.*xyz`. — Wiktor Stribiżew, Mar 01 '16 at 09:48
Thank you. I managed to do it with that answer :). This is for puppet. Which is using Ruby. That is why I forgot to mention it. Sorry. — kereza, Mar 01 '16 at 13:30

You should tell us with which language you are coding, regex engines are not always the same.

There is another ambiguous point : Do you need your string to CONTAIN xyz or to END WITH?

Considering you are coding on Javascript..

If you want it to contain xyz, try :

/^abc1.*xyz/

If you want it to end with xyz, try :

/^abc1.*xyz$/

*and contains the letters "xyz"* - Perhaps, OP wants `[xyz]`? Also, there is no need in the second `.*` in your first pattern. – Wiktor Stribiżew Mar 01 '16 at 11:51
That worked for me. Thank you. /^abc1.*xyz/ – kereza Mar 01 '16 at 13:32
