Is it possible to add and element to a foreach loop while looping the elements

Hello All,

I wounder if the following is possible as I have a situation where this would be useful.

let says I have a variable called $ListOfFiles that reads in a text file containing the names of 8 files for example.

Next I do this

foreach ($File in $ListOfFiles) {

Do some stuff

}

Now the thing is the text file containing the list of files can contain wild card entries entries like so

File1.txt
File2.txt
SomeOtherFile.doc
MyFile*
YetAnotherFile.xls

Therefore in the above "do some stuff" section I need to read in all files which have the * wild card at the end of their name i.e.

if ($File -match "\*$") {GCI  \Dir1\$File etc.........}

I need to process these additional files (let's say there are 10 which start MyFile) in the same manner I am processing the foreach $file on $ListOfFiles

I believe the $LostOfFiles is read in once at the start

So is there any easy way my be Clear-Variable ListOfFiles then += to make my single foreach loop process all files?

Thanks

Ernie
