I have the following EDI file and need to filter the element LOC 11 but not the LOC 7 and I need all segments between them that the LOC Segment gets repeated but the segments between them not.
At the moment my regex looks like LOC[^L]*(?:L(?!OC)[^L]*)* but with that I get 4 results because it filters the loc 7 elemements too.
I only need the 2 results. Could you help me?

CodePudding user response：
You can use
LOC\ 11[^L]*(?:L(?!OC\ 11)[^L]*)*
LOC\ 11[\w\W]*?(?=LOC\ 11|$)
See the regex demo.
Details:
LOC\ 11-LOC 11string[^L]*(?:L(?!OC\ 11)[^L]*)*- any text up to the first occurrence ofLOC 11substring (uses the unroll-the-loop principle).
Although the results you get with the two patterns above are identical, the first one is much faster provided there are not too many Ls that are not followed with 11.
