Okay, So to extract the ssid and psk from the file, you can try this :
ssid="([\w ]+)"|psk="([\w ]+)"
where it searches for
-->ssid=" and extracts the content within the ". Similarly for the psk.
There is a OR between them so it will search for both the words. You can get the extracted data with the help of numbered groups.
PS: Do not forget to escape the characters.
