Regular Expression Resources

PDQ Inventory supports regular expressions to help you create dynamic collections and reports that filter criteria based on text that matches a given pattern. If you would like to use regular expressions within your filters, you can set the Comparison column of that filter to either "Matches Expression" or "Does Not Match Expression" and then input a standard regular expression into the Value column. Regular expressions can also be saved as custom variables within PDQ Inventory and then referenced in your filters rather than inputting them directly into your dynamic collection or report.
