I searched in a xml file with this expression: EXTERNEC="[\w\d\-\:\=]{20,}" Then it will find a match in data like this: .... SCORE="0" EXTERNEC="225419007:392521001=87279008"><next_element .... I hit next and it finds a next match. But when I then click previous it will not find the previous it did find on first search. Strange.....
