Can you expand/improve the regex pattern so you don't have rescan the string to check for the presence of MeasDisplay and PatternFov? In other words, since you're already using the giant, Swiss Army sledgehammer of the re module, go ahead and use enough features to cover your use case. -- Neil Cerutti -- https://mail.python.org/mailman/listinfo/python-list
