need help with filter and regex

[Tiemo Hollmann TB]

Hello,

 

in the course of the massiv LC 7 problem with sort international (which is
approved by Runrev) I am looking for a workaround for my repeat selection
and sorting with filter, as Richard H. advised.

 

I don't have much experience with filter, beside of some easy filters nor
regex. Today I am selecting records from an array with multiple selections
in a repeat loop. If a combine this array to do a filter on it, it looks
like this:

Key;string1;string2;number1;number2;string3; etc.

Today I am selecting like: if string1 contains/begins with searchitem and
number2 is/is not x then

1.       I don't understand whats the difference between filter with /
filter matching

2.       As far as I see, I don't get here far with a standard filter and
probably would need a regex to specify in which item of my line I want to do
the selection. Perhaps with the number of semicolons?

Any initial help with a regex filter on this issue is appreciated.
