How to parse a file and store few strings in an array
-
Try this:
BOOL bCapture = FALSE; // flag to ignore unwanted tokens
while(fgets(buf, bufsize, fp1) != NULL)
{
tok = strtok(buf,"{ ,}");
if (tok != NULL)
{
if (bCapture == FALSE)
{
// not capturing yet, so check for start of list
if (strcmp(tok, "EXEC") == 0)
bCapture = TRUE;
}
else // bCapture == TRUE
{
// bCapture is true so check for end of
// list, or display token
if (strcmp(tok, "END-EXEC") == 0)
bCapture = FALSE;
else
printf("Token: %s\n", tok);
}
}
}[edit]Fixed the "END-EXEC" string, thanks to Carlo for pointing it out.[/edit]

My 5, though your code, as it stands, wouldn't match the-requirements. :-D

I wrote it over breakfast; what's missing?

Nothing is missing, however an underscore is not an hyphen. --Carlo The Nitpick.

That code was a beauty again .... :-D Actually... the final file after strtok() looks like the one below... :|

Token: THEYour code cleverly extracted the strings within EXEC and END-EXEC which I stored in
char tableCol[6][10]
But now I am finding it really difficult to store the strings which are immediatedly followed by the "tabCol" string from the file... :( ie CN-POLICY-NO, CN-REG-NO, CN-EFFECTIVE-DATE, CN-EXPIRY-DATE, CN-CAN-EFF-DATE, CN-CAN-PRO-DATE, CN-RETURN-PREMIUM & CN-CAN-PROCESSED which are to be stored in
char tableRow[6][10]
Apologies ...:( Thanks a ton, Faez

Since they all begin with "CN-", you could add a test:
if (strncmp(tok, "CN-", 3) == 0)
printf ...Alternatively you have to test for each one individually.

No no... It ain't always preceeded with "CN-" string ... The strings which needs to be stored in TabRow array are followed by the second occurrence of each tableCol values... Initially I also thought of using strcat () and append CN- to the tabCol values... But den I realized that it was for this file only... Other files are completely different. Regards, Faez

If you don't have a common character identifier to select your strings then there is little that can be done. And from what you say you will have different rules for different files so it's difficult to suggest any other options.

Finally I have come up witha Not-so-good code... But it works.. :) I created another similar situation to parse from END-EXEC to End of File as below...
if (k == 0)
{
if (strcmp(tok, "END-EXEC") == 0)
k = 1;
}
else
{
if (strcmp(tok, "THE") == 0)
{
k = 0;
}
else
{
strcpy(tabRow[m],tok);m++;
fprintf(fp3,"Token: %s\n", tok);}}
}
}
// Out of all the loops and condition now....j=0,n=0; for(j=0;j<=m;j++) { if(strcmp(tabCol\[n\],tabRow\[j\])==0) { k=j; strcpy(tabRow\[n\],tabRow\[k+1\]); n++; } else ; } for(k=0;kIt wud be nice to get ur comments on this... :-D

Thanks,
FaezDifficult to say really. Assuming it does what you want then that's fine, but I don't see any checks for the specific strings after the "END-EXEC" that you wish to save. Or perhaps that is what the line
if(strcmp(tabCol[n],tabRow[j])==0)
is doing.
