阅读更多关于 Matches not captured when using -SimpleMatch with Select-String

问题 I have been using regex to parse text within some XML nodes. However, when I use -SimpleMatch with Select-String , the MatchInfo object doesn't appear to contain any matches.

问题 I'm trying to create a script that will find the most recent build_info files from multiple install locations in a server's directory, select the "version: " text from each file, and compare them to see if they're all the same (which is what we hope for), or if certain install locations have different versions.

I'm trying to extract text from a set of files on Windows using the Powershell (version 4): PS > Select-String -AllMatches -Pattern <mypattern-with(capture)> -Path file.jsp | Format-Table So far, so good.
