How To Split Value From Delimiter.

How to split 'cookie' by seperating the delimiter '|' ?

cookie="item 1 : desc2 | item2 : desc2";

Assume the value of 'cookie' is not fix. I want use the
while loop to display each item where the format is
separated by "|".

Eg. my expected output as below :

item item desc
----- ---------
item1 desc1
item2 desc2

Please help. Thank.

You could use the strtok()function.

char cookie[1024];
char * ptok;
strcpy(cookie, source_of_cookie);
ptok = strtok(cookie, "|"
while(ptok) {
printf("\n%s", ptok);
ptok = strtok(0, "|"
}

This will produce something like this
cookie="item 1 : desc2
item2 : desc2";

To get rid of <cookie=&quot;> call 1. strtok with parameter cookie + xx instead of just cookie.

I,

my post may be not appropriate in this forum, the right
has done already JOLESEN.

If you are working at a Unix env you don't need to write
a c-program only for this purpose.

Using &quot;awk&quot; command line ( FS='|')you will have this and more possibilities.
AWK is not a simple command but in pratic a programming Language: it is intepreted.

The details are out of the scope of forum, but if you need
post again.

bye

Hello JOlesen,

I almost done on my part. Thank you very much for
your help.

I got another problem. How to split again item1
and desc1 seperately by &quot;:&quot; delimiter ? I had tried
to use sscanf(), but it never work.

I may think if my desc or item got space (eg &quot;item 1&quot,
sscanf will never work. But without space (eg &quot;item1&quot, the
program will work accordingly. My description definately
got space in between.

Please help.

==== my program =====
char cookie[1024];
char item[50],desc[50]
char * ptok;
strcpy(cookie, &quot;item 1: desc 1 | item 2: desc 2&quot;
ptok = strtok(cookie, &quot;|&quot;
while(ptok) {
sscanf(ptok,&quot;%s:%s&quot;, item, desc);
printf(&quot;\n%s == %s&quot;, item, desc);
ptok = strtok(0, &quot;|&quot;
}

You are right : sscanf is not really good for this.

You could use strchr() to find/locate the ':'.
If ':' is found, copy what's located between ptok and ':' to variable item . Also copy whats located *after* ':' to desc.
