regular expression

8 posts in this topic

Hello

I'm working on log file parser, file handling/reading is done but clueless about how to parse out specific data (latitude/longitude figures).

Obviously I need to use regular expressions but that stuff seems to go right over my head for the moment

Sample of a line:

2014-03-02 14:12:27 | Current location: Unknown, Lat: 58.88°N, Lon: 94.39°E, Altitude: 105 m
 
I am triying with regex tester at http://regex101.com
 
Q1: what should I use in expression for "Unknown? It may change, have several words for place names, only certainty is "," between it and Lat but location name is not important by itself. What I want is xx.xx numbers right side of a Lat: and Lon: and capture the numbers.

shaqan,

This works for me:

#include <Array.au3>

$sString = "2014-03-02 14:12:27 | Current location: Unknown, Lat: 58.88°N, Lon: 94.39°E, Altitude: 105 m"

$aRet = StringRegExp($sString, ":\s(\d{1,3}\.\d{1,2}°[NSEW])", 3)

_ArrayDisplay($aRet, "Lat/Long", Default, 8)
SRE decode:

:\s        - Look for a colon followed by a space
(          - Start capture of anythig that matches:
\d{1,3}    - 1-3 digits (1 - 180)
\.         - a decimal
\d{1,2}    - 1-2 digits (0 To 59)
°[NSEW]    - ° followed by one of NSEW
)          - Stop capture

3          - Return an array of matches
All clear? :)

Edit:

If you need the location as well then this should work:

$sString = "2014-03-02 14:12:27 | Current location: Unknown, Lat: 58.88°N, Lon: 94.39°E, Altitude: 105 m"

$sExtract = StringRegExpReplace($sString, ".*:\s(.*),\s.*:\s(\d{1,3}\.\d{1,2}°[NS]).*:\s(\d{1,3}\.\d{1,2}°[EW]),.*", "$1: $2 $3")

ConsoleWrite($sExtract & @CRLF)
I will let you work out how that one decodes. ;) Edited by Melba23

mikell,

What would you (and jchd) do without my poor SRE attempts to keep you amused? :D

Sure ! 

As each SRE problem is a challenge by itself, it's a nice way to have fun  :)
