When you post code use code blocks.

If I opt to use QRegularExpressionMatchIterator i = re.globalMatch(pattern);


Not sure how to emphasize what I have already said several times.

That question is NOT about regular expressions.

It is about how to use that specific library.

I suggest you start with a less difficult example to figure out how iteration works. And google for examples as I documented in the other reply.

You mean the parens. Parens are used for 'capturing' and for 'grouping'.

For the case I gave the inner ones was to group the outer for capturing.

And yes that is a problem when you iterate. The library you are using might have a way to specify that the parens are not 'capturing'.

In Perl it looks like the following. There would be only one capturing group which would match either 'abcxyz' or 'defxyz'.

((?:abc|def)xyz)


I will note that I use that feature so rarely that I had to look it up.

the analysis of "xx:"


As I mentioned there are variations to what I suggested. Myself I don't care for using '{2}' in a case like this. Just a preference.

(Had to edit the above because I messed up the code block)
