Hello,
You might find this macro useful:
Macro that extracts lines that contain the specified string:
/modules/mydownloads/singlefile.php?cid=8&lid=169
Macro that extracts lines that do not contain the specified string:
/modules/mydownloads/singlefile.php?cid=8&lid=170
In future versions of EmEditor, I will add this kind of feature to easily delete bookmarked lines, and bookmark matched lines after searching.
Thanks!
