I have the following Powershell script to search a string pattern in all files in a folder. If the pattern does not exist then it adds the string as expected but at the end of the file. I would like to add the string to a specific line number after line 106. This is the same for all .CONFIG files in the folder.
How can I add this to my existing script as I have tried

Attempting to convert Terminals (Robert Chartier) favorites file to mRemoteNG config file. Both files are XML. I need to loop through the favorites file that looks like this (C:TemptempTerminals.xml):

I’m working on modifying xml files from an existing system using PowerShell. Our system supports using multiple nodes in one body, and depending on what the OuterXML is set as, it will bypass that value and use the other node of similar value (I suppose this may be true of all XML files but I do not want to make poor Assumptions).
