Notepad++ regex for text surrounded by double newline

I am trying to find all text blocks in a file, that contain a string, matching the following regex: D[:\/\\]+Apps[\/\\]+ and are surrounded by double newlines.

For example in this text:

00,36,00,31,00,39,00,33,00,34,00,65,00,30,00,38,00,39,00,00,00,00,00,00,00,\
  00,00,00,00,00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v2.0.50727\NGenService\Roots\D:/Apps/Microsoft Visual Studio/2022/Community/Common7/IDE/CommonExtensions/Microsoft/Architecture Tools/GraphProviderPackage/Microsoft.VisualStudio.GraphProviderPackage.dll]
"Status"=dword:00000003

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v2.0.50727\NGenService\Roots\D:/Programs/Microsoft Visual Studio/2022/Community/Common7/IDE/CommonExtensions/Microsoft/Architecture Tools/GraphProviderPackage/Microsoft.VisualStudio.GraphProviderPackage.dll\0]
"Scenario"=dword:00000020

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v2....

What I want to be found is:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v2.0.50727\NGenService\Roots\D:/Apps/Microsoft Visual Studio/2022/Community/Common7/IDE/CommonExtensions/Microsoft/Architecture Tools/GraphProviderPackage/Microsoft.VisualStudio.GraphProviderPackage.dll]
"Status"=dword:00000003

Having in mind, that "Status"=dword:00000003 is on a different line

So far this is the closest I got:

\r?\n\r?\n(([\s\S](?!\r?\n\r?\n))*)D[:\/\\]*Apps[\/\\]*(([\s\S](?!\r?\n\r?\n))*).\r?\n\r?\n

but Notepad++ says that my regex is invalid, even though in regex101 it matches it the way I want it.

Solution

  • Explanation:

    \R\R            # 2 any kind of linebreak
\K              # forget them
\[              # openning square bracket
.+?             # 1 or more any character, not greedy
D:/Apps/        # literally
.+?             # 1 or more any character, not greedy
(?=\R\R)        # poritive lookahead, make sure we have 2 linebreak after
