Simplify the target="_blank"

Simplify the target="_blank"
Hmmm. It erased my code... In place of the |XX| in the -replace= you can concatenate in the following: (#newWindow ? 'target="blank"' | '')

Simplify the target="_blank"
You can simplify the code by not using the |XX| and instead put the logic for it there. In other words, the -replace= could look like this: -replace='\\1\\2'
