Parse Lots Of Text Being Returned From A Function

[TonyJ]

I am using a StepType our Company developed which is used to get information on available access points our portable router can see.  After I send a status command the device will send a long list of access points (see example below).  How do I parse this output to get the RSSI for a particular SSID.  For example in the sample below how would I return the value of RSSI, -63dBm for SSID WKRP1?  Your thoughts on how to tackle this problem.  Thanks.

BSS 0:
SSID: \x00
BSSID: 00:1c:b1:88:b9:80
Channel: 1
RSSI: -72 dBm
bssType: Infrastructure
Security: wep-on

BSS 1:
SSID: WKRP1
BSSID: 00:0a:b8:7f:85:10
Channel: 4
RSSI: -63 dBm
bssType: Infrastructure
Security: wpa-psk-tkip

Personally, I would pass the entire string into a VI and pase it in LabVIEW.  You can then use Regular Expressions or simple searches to get the information you want.

Can it be done without Labview in particular from Teststand?  If so, how?

Hi Tony,

It can be done without LV but i feel its always easy to do in LV or any C based language.But if the requirement is minor and can be easily done through TestStand then its fine avoiding a vi or a dll.

I am attaching a example sequence which gives RSSI value from your example text.

This is what i did :

use split function to split all values into a string array.

Looked for a split string which contains RSSI

Took the next string which had RSSI value and converted it to number using val function.

If the text of interest  is always in a  fixed position then you can use functions like mid or left  to grep the required text of interest.

Then use function like val( str) which converts this to a number.

Hope this helps.
