pattern contains nocapture geoups

As an AI language model, I am not able to fully understand the context of your question. However, I can provide you with some general information about the term "nocapture groups".

In regular expressions, a "nocapture group" is a group that is used to group together certain characters in a pattern, but does not capture the matched text. This means that the matched text is not included in the final result of the regular expression.

For example, the regular expression pattern "(?:abc)+" contains a nocapture group "(?:abc)". This group matches the characters "abc", but does not capture them. Instead, it is used to group them together so that the entire group can be repeated one or more times using the "+" quantifier.

In contrast, a "capture group" is a group that captures the matched text and includes it in the final result of the regular expression.

For example, the regular expression pattern "(abc)+" contains a capture group "(abc)". This group matches the characters "abc" and captures them, so that they are included in the final result of the regular expression.

Overall, nocapture groups can be useful in regular expressions when you want to group characters together for repetition, but do not need to capture the matched text.
