Regex replace multiple consecutive string occurrence with single instance or the same string

Hi @takashi,

Thanks very much, that has worked a treat.

(As an aside I had already used one of your previous posted answers to remove multiple consectutive spaces \\s{2,}. I had tried to tweak this to remove the flags but had not managed it.)

Thanks again,

Rob

Hi,

U can do that using regsub in a (for instance) attribute creator using the Arithmitic editor.

[regsub -all -line {(\\(TMP_flag\\))\\1*} )} {\\1}]

test is the attribute I used to hold your examples.

nd

1. I capture (TMP_flag) by regexp (\\(TMP_flag\\)) whereby enclosing braces are escaped \\( and \\) and the outer braces define the capture group.
2. The curly braces are needed because your string contain spaces, braces and underlines (double quotes will yield a error)
3. the \\1 denotes the (first) capture group. Needs to be in curly braces because of the braces in the capture group.
4. switch "-all" finds all matches and "-line" to do it till end of line.

Stringreplacer transformer can alos be used:

Text to match: (\\(TMP_flag\\))\\1*

Replacement text : \\1

Use regular expressions: Yes

A must to have in your favorites list.

lol...I took too much time typing.

Hi @gio

Thanks for the answers and the explanation of the regex processing.

I need to spend more time on understanding how it works as it is very powerful, when you know what you are doing. :-)

Hi @gio

Thanks for the answers and the accompanying explanation as to the Regex processing.

I need to spend more time learning/working with this to develop my skills, it is a really powerful tool when you know what you are doing. :-) (one day hopefully)
