I would appreciate your help with the regular expressions. I have a
document consisting of hundreds of lines. A small sample is here:

Set:   01SA34509
Set:   0134501
Set:   0111679SE

I need to delete all text except these lines started with word "Set".
If I use "set:.+" regular expression, all these lines, that should be
kept, are selected. I cant find a way to reverse this selection. I
tried "[^set:.+].+" and "[^(set:.+)].+" but they don't work. Could you
please give me any clues?

I think this is fairly simple.  I'm assuming that your "lines" are
actually separate paragraphs, in fact: that they are separated by
paragraph breaks, not line breaks, that is.

o Using Find & Replace with "Regular expressions" ticked, search for
^Set and click Find All. This will select just those words, where they
occur at the start of a line, not the whole lines.
o Click the down-arrow at the right of the Apply Style window in the
Formatting toolbar, and select some (paragraph) style different from the
style of your text (perhaps Heading?).  Since this is a paragraph style,
it will apply to the whole of each relevant line (paragraph), not just
the selected occurrences of the word "Set".
o Back in the Find & Replace dialogue, click "Search for Styles", choose
your original style (perhaps Default?) in the "Search for" box, and
click Find All.
o Press Delete to remove all the unwanted lines.
o Tick "Regular expressions" again, and search for ^$ - replacing with
nothing.  Click Replace All.  This removes the empty paragraphs left by
the previous process.
o Go to Edit | Select All (or press Ctrl+A) and use the Apply Style
window again to reset your paragraph style appropriately (to Default?).

I trust this helps.

It seems to work indeed. Thank you very much :-). Regards,
