Give this a try:

   ... 
| rex field=mydata "^.*>(?<Process>.*)$"

This will run anywhere:

| makeresults 
| eval mydata="'ProcessName'>C:\Windows\System32\lsass.exe"
| rex field=mydata "^.*>(?<Process>.*)$"

The regular expression will pull out any characters after the ">" and before the end of the string as the Process field.

If the separator between key and value were and = sign, Splunk would already have figured that out. 🙂

For your problem, though,

... | rex field=Process "'ProcessName'>(?<ProcessName>.*)"

After that you'll have a field named "ProcessName" just like you want.

Happy Splunking,
Rich
