How to trim current pipeline object in PowerShell?

I often paste input into ISE and sometimes it needs trimming empty lines and leading/trailing spaces, so I need to  pipe it to trim those:

$lines = $null

$lines = @"



"@ -split "\t|\r?\n" |?{$_ -match "\w"} |ForEach-Object {($_ -replace "").trim()}

So, using $_ -match \w covers me when the lines contain letters and/or numbers, which works in my particular case, but I assume there is a proper way to exclude empty lines?

Also, ($_).trim() doesn't seem to work, so I am having to do something to $_like $_ -replace ""  (which I am hoping does nothing?), before trim actually works. So, what is the proper way to trim the object in the pipeline? I am guessing turn it into a string somehow?

Or is there a better way of doing all this altogether?

My goal is basically paste some input into ISE, split it into a multi line object, remove the empty lines, and trim the remaining lines.

Thank you!
