I get syntax error

[a@b.com]$ cat output3 | awk '/isotime/ { sub(/<.*/,"",$3) ; print $3 }'
awk: syntax error near line 1
awk: illegal statement near line 1

If on Solaris, use nawk

Can you please explain how it works.

nawk works vgersh99 thank you .

nawk '/isotime/ { sub(/<.*/,"",$3) ; print $3 }'

Here is explanation:

Code:

nawk -F'[<>]' '/latitude/ {             # Set < > as field separators. Search pattern: latitude
                LA=$3;                  # Set LA = 3rd parameter (tag latitude value)
        } /longitude/ {                 # Search pattern: longitude
                LO=$3;                  # Set LO = 3rd parameter (tag longitude value)
        } /isotime/ [                   # Search pattern: isotime
                TS=$3;                  # Set TS = 3rd parameter (tag isotime value)
                sub(/.* /,x,TS);        # Remove everything before last blank space
                sub(/\[.*/,x,TS);       # Remove everything after opening square bracket
        } END {                         # END
                print LA, LO, TS;       # Print value of variables LA, LO, TS
} ' xmlfile

thank you for the information DGPickett . Do you have a shell script that can give the output i posted

First, you need a database of all the national spaces where tz is not normal, an hour off GMT for each 15 degree zone, starting with +/- 7.5 degrees longitude = GMT or UTC. Looking at the map, it seems more the exception than the rule, so one needs a database of all the state, province or nation political boundaries to extract those that are time zone boundaries. Since many follow rivers or coastlines, it will not be a small database, and it may be in vectors where the boundaries lie, so you need a program to decide if your lat-long is inside their multifaceted polygon. I am not into maps that deep, but I can imagine someone has some sort of app and db that does lat-long to political. Maybe the database can have a lot of lat-long "rectangular" boxes so it becomes a relative simple query. You could take a vectors of boundary database and generate even more rectangles. How fine is fine enough bubbles up very quickly as a requirement question!

excellent bipinajith . thank you for the detailed explanation . It really helps.
