How do I filter part of a string using regex?

Question

Using PowerShell I am able to get the lines from a file which contain the needed text:

Get-ChildItem -recurse -Attributes !Directory+!System | Get-Content | Select-String "tshtml"

This gives the result below:

 templateUrl: '/tshtml/generic/gkeyvalue/gkeyvalue.html'
 templateUrl: '/tshtml/generic/permission/permission.html'
 templateUrl: '/tshtml/generic/permission2/permission2.html'

But now I want part of this as output:

 /generic/gkeyvalue/gkeyvalue.html
 /generic/permission/permission.html
 /generic/permission2/permission2.html

How do I do that? I am reading about regex, but I am not getting much about it :(

... | Select-String "tshtml" | ForEach { $_.Line -replace "^.*(?=/generic)|'$" }

To replace the start of a line leading up to /generic, and the ' from the end of the line, with nothing.

or

Select-String "tshtml" | ForEach { if ($_.Line -match "'/tshtml(.*)'") { $Matches[1] } }

To capture the text between the '' and output it.

Even simpler for the section option: ...|Get-Content|?{$_ -match "'/tshtml(.*)'"}|%{ $Matches[1]} There's no need for the Select-String and then matching, just do it all at once.

@TheMadTechnician yeah. Or use select-string to do it all at once ... | Select-String "'/tshtml(.*)'" | ForEach {$_.matches[0].groups[1].Value}

Try the below:

... | Select-String "tshtml"|awk '{print $2}'| tr -d "'"

Assuming you have a Windows build of awk and tr to use, the output of Select-String converted to plain string includes the filename as well, so this would need to be {print $3} to get the right output.
