thank you
that worked fine!!!

You could use the “Mark” tab in the search and replace dialogue. Have Bookmark line ticked. Search for the lines that have the string, then use menu => Search => Bookmark => Inverse bookmark**. Now the lines that do not match the search string are bookmarked. The Bookmark menu has several other commands for manipulating the (un)marked lines.

Notepad++ freeezing is a ‘sign’ that this particular UDL is not a valid file.
Using N++ to check gives me the following error:
“XML Parsing error at line 10: extra content at the end of the document”

Hello, Guy,
In a reply of about a montha ago, you wrote “Be aware that, UNLIKE script languages, as Python, or Lua, regexes CANNOT store all successive values of the groups !”.
The good news is now that I have a set of working regexes for some sorts of indexes. I would go further now, but It turned out, that the amount of characters that a regex can handle is too small for my goal. So I think I have to use python to do the trick. I know a bit of programming (I learned the basics of algol and fortran some 50 years ago), but I did not do that job for years, so I fear that it will take some time before I am able to make working python-scripts. Therefor, I would like to ask you some questions so I don’t have to read lots of documentaries and forum-discussions which might be irrelevant for my limited goal.

Thanks in advance, best regards, Jos
