Notepad++`在文件中查找`显示除某个关键字之外的所有结果

Question

I am using notepad++ to search for certain keywords (using regular expression). something like (word1|word2|this statement|another statement). It works but can I search and show all results except a certain keyword? something like exclude the following words (exclude this|exclude this)? For example, below.

samedir\\File1.log

This is line 1
This is line 2
This is line 3
exclude this
This is line 4
This is line 5
This is line 6
not excluded
excluding this

samedir\\File2.log

This is line 1 1
This is line 2 1
This is line 3 1
exclude this
This is line 4 1
This is line 5 1 1
This is line 6 1
not excluded
excluding this

For example: I want to start a find in both files (on the same directory) but exclude the lines with excluding this and exclude this the results should show something like below

File1.log

This is line 1
This is line 2
This is line 3
This is line 4
This is line 5
This is line 6
not excluded

File2.log

This is line 1 1
This is line 2 1
This is line 3 1
This is line 4 1
This is line 5 1 1
This is line 6 1
not excluded

Answer 1

You can do this with a lookahead assertion:

^(?!excluding this|exclude this)[^\\r\\n]*$

This will match entire lines as long as they don't contain excluding this or exclude this .

The key is the (?!) part. See http://www.regular-expressions.info/lookaround.html for more info.

Answer 2

You could try the regex like below to match all the lines which don't have exclude or excluding this strings.

^(?!.*\bexclud(?:ing|e) this\b).+$

DEMO

This (?!.*\\bexclud(?:ing|e) this\\b) negative lookahead at the start asserts that there isn't a string exclude this or excluding this present on the the line in which we are going to match. That is , the above regex would match all the lines except the one which contains exclude this or excluding this

Answer 3

I wanted to exclude one string and search for two strings in one line, so I used this regex:

^(?!.*excludethisstring).*includethisstring1.*includethisstring2.*$

This will make it so that the one line searched MUST have the two strings included, if you want to search for either one of the lines:

^(?!.*excludethisstring).*(includethisstring1|includethisstring2).*$
