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
0109SA
011017B
01020207B
010902B
01090002
011007B
01090001
090110
Set:   0134501
011101
01110102
01110103
080908
Set:   0111679SE
0111SE

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.
