I think you may have misinterpreted my comment. My comment was not directed at your choice of words. My point was that there are many askers who visit "here" (this forum) and ask questions without having a full command of the basics of the forum (maybe it's due to a basic spoken language barrier or just ignoring the posting rules). In any case, most of those that visit ask a question with less than full information and after they receive some sort of answer they never return. While I would like full information at the first post as is requested at the top of the forum, I have come to realize if I want to answer the questions it takes patience to work with the asker. That's all, nothing much else to be read into my comment.

Thank you for your (calm) explanation: I misinterpreted your reply. Please accept my apologies for my snippy answer!

What did you not understand about the request for a detailed explanation of your problem?
I can understand your frustration but patience is the key to answering questions here.
What do you mean by "here"? Is this forum some special place on the internet?
I asked the OP a question which he either ignored, or didn't understand. If it was the latter, s/he just needed to ask for clarification instead of mindlessly posting another nonsensical one-line-question.
With all due respect: as long as I am not abusive towards other forum members (which I'm not, IMO) and what I post is "on topic", I will post whatever I like. Thank you.

qwerty53, if you want to match as your described in the title of the question you would need to use capture groups and then replace capture group 0 with the three capture groups used:

$sourcestring before replacement:
1x2x3x4x5x6x7x8x9x

Raw Match Pattern:
((?:.*?x){3}).*?(x(?:.*?x){3}).*?(x.*)

Raw Replace Pattern:
$1$2$3

$sourcestring after replacement:
1x2x3xx5x6x7xx9x

I want to capture all chars but those I skip

If that is the best explanation you can give, I'm out.

Good luck.

qwerty53, you cannot skip characters in a capture group (in your case capture group 0), the best you can do is create capture groups with ( ) such as:

(z)[^z]*(z)

capture groups 1 and 2 are your target.

I don't know what you are trying to do but it doesn't sound like a regex problem

What do you mean by "skips"?

A more detailed explanation of what you're looking for would help.
