Can someone recommend a good resource(ebook, blog posts, etc) to learn the regex techniques which can be used with powershell? All the resources I came across so far are concentrating more on other programming languages like php, perl etc. While I understand the basics of it, it would be nice if we have any such topics which has some powershell examples or with examples which can be used in powershell. I have already gone through the built in powershell regex help information and would like to learn little more deeper. Thanks in advance.
