Regular Expressions in Powershell

As part of a script I am working on, I needed to parse some web content which was stored on a remote server; in this case, I needed to scrap a particular set of web links of the page and report back.

The best way to get content of the internet from within a script is wget, which from within Windows you can make use of the GNUWin32 project. I will post about how useful this project is to Windows Scripting and administration later!

Back to the topic at hand.

After getting the content from the web and saving it as a file, I then put the content into a variable using Get-Content, from there, searching the content was pretty easy. First you need to make a RegularExpression.Regex object, and from there, you can feed any string into that object, and it will return the matches.

For Example:
