title: Powershell Regex check for string between brackets
body: <p>I'm trying to read values from a text file into a hashtable, I want to be able to be able to tell when I encounter a value that has the format "['somestring']"... So when I encounter a value that has brackets around it I want to store the string into a specific variable and run a function with that string. </p>
  
  <p>I was thinking that regex was the way to go for this but I am unsure what a possible regex value would look like. Any help would be appreciated thank you!</p>
