I’m a powershell newb. There I said it. Now let me learn. Here’s what I created after some google searches.

1. Go through all files in a directory

   Get-ChildItem . -r -file

2. Filter on xml files

   Where { $_.Extension -EQ '.xml'}

I think this can be added to the Get-ChildItem command, have fun optimizing this 🙂

3. Take only the files that match a XPath

   Select-Xml -XPath "XPATH_HERE"

you can test the xpath with online tools like this one

4. Copy the file to a directory

   Copy-item -Destination DESTINATION_DIR_HERE

   this takes the Path from the Get-ChildItem, make sure to use -Destination to avoid parameter exception as described here

Complete line with pipes

Get-ChildItem . -r -file | Where { $_.Extension -EQ '.xml'} | Select-Xml -XPath "XPATH_HERE" | Copy-item -Destination DESTINATION_DIR_HERE
