Regex pattern search in TextPad fails, works in Visual Studio

I'm trying to use TextPad to search for a regular expression in several files. I have a simple pattern but it doesn't work in TextPad. It works fine in Visual Studio.

A开发者_开发知识库nyone have any ideas?

I'm searching for:

hosted.mysite.com or host.mysite.com

using the pattern:

(hosted|host)\.mysite\.com

Use something like this

\(hosted\|host\).mysite.com

try this:

 host\(ed\)?\.mysite\.com

Not every text editor uses the same regex/conventions. A regex you may get to work in Visual Studio won't necessarily work in Eclipse, Netbeans, or some other IDE or text editor.

In Textpad you need to escape some characters, such as parenthesis and pipes.

In your case, what you need is this:

\(hosted\|host\)\.mysite\.com

Note: you need to escape dots as well.

Textpad's POSIX regexes are good, but even better results could be achieved by installing the Win GNU util grep and adding a cmd /c "Prompt for parameters " , "Capture output" command: thus you could have full Find in files with even Perl regexes: grep -nhPr "CoolRegexToSearchWith" C:\MyDir\ToSearchRecursivly
