Hi, I can confirm some problems in code explorer in PSPad 5; with the mentioned XML sample file: https://msdn.microsoft.com/en-us/library/ms762271(v=vs.85).aspx
In PSPad 4.6.2 parsing the xml in code explorer runs instantly, as well as refreshing after deleting some element. In PSPad 5 (243) I can see a rather long delay on each refreshing the code explorer, both after deleting some elements but even without changes in the code. Even for such 4,5 kB short sample the parsing and freeze of the aditor takes over 8 minutes on an older laptop (Win7 64bit, 4 GB RAM) The process of PSPad.exe takes 25% (i.e. the maximum load for 4 (virtual) cores) It might be somehow specific, as the delay didn't happen on some other XML samples (or parts of the sample) I tried. If I add the "book" elements of the sample individually and refresh the explorer each time, there starts to be a delay of a few seconds at 9th item (bk109) and the delay increases rapidly on each next added "book". It seems, there might be some excessive parsing, regex backtracking or similar. vbr -- <http://forum.pspad.com/read.php?6,69090,69196> PSPad freeware editor http://www.pspad.com
