How can I split a String or a Char

Projects Programming

Dear All,

I am looking to split a string as would do explode in PHP.

Here is code with explication

boolean sms_read(int sms_pos,char sms_from_number, char *sms_date, char *sms_time, char *sms_text)
{
  // Definy a variable
  char cmd[12];
  // Set the command
  sprintf(cmd,"AT+CMGR=%d,1",sms_pos);
  //Send the commans
  sendATcommand(cmd,"OK",2000,true,false,true); // This work.

  // sendATcommand will save the repsonse into a buffer call buffer_by_line. Each line will be save in a row. See below
 
  
  // It check the content of buffer_by_line
  for(int b =0; b<NBLINES;b++)
  {
    Serial.print(b);
    Serial.print(F(" : "));
    Serial.println(buffer_by_line[b]);
  }
  /* Display buffer_by_line
  0 : AT+CMGR=2,1
  1 : 
  2 : +CMGR: "REC READ","55555","","13/09/08,14:25:34+08"
  3 : Das von Ihnen gesendete Keyword ist leider falsch. Le mot cle envoye est malheureusement faux.
  4 : 
  5 : 
  */
  
  // I display the SMS reveived message
  Serial.print(F("Message :")); Serial.println(buffer_by_line[3]);
  
  // Now I need those part: 5555,  13/09/08 and 14:25:34+08
  
  // Donc j'utilise une des fonction de _pepe_. Mais ca bug de mon cote
  splitString(buffer_by_line[2], splitedString, ",");
  
  Serial.print(F("From :")); Serial.println(buffer_by_line[2]);
  
}

Juste above I am using a function to split the content of buffer_by_line[2] in order to have the result as follow

0:+CMGR: "REC READ",
1:"55555",
2:"",
3:"13/09/08,
4:14:25:34+08"

I still need to remove all ".
In php, there a function str_replace('"',''); Is there something similar woth C++, to remove "??

That line

 splitString(buffer_by_line[2], splitedString, ",");

generate that error

sim908_cooking:814: error: cannot convert 'char*' to 'char**' for argument '2' to 'void splitString(char*, char**, char)'

However splitString() ask 3 char, and I sent 3 char, no????????

I also tryed

char *c = strtok(buffer_by_line[2], ",");
  
  for(int cc=0; cc<strlen(c); cc++)
  {
    Serial.print(cc);Serial.print(":");Serial.println(c[cc]);
  }

which display

0:+
1:C
2:M
3:G
4:R
5::
6:
7:"
8:R
9:E
10:C
11:
12:R
13:E
14:A
15:D
16:"

Here is the function splitString()

// SlitString
#define NBVALS 14
char splitedString[NBVALS];
void splitString(char *ligne, char **splitedString, char delimiter)
{
  char *p = ligne;
  int i = 0;
  splitedString[i++] = p;
  while (*p) {
    //if (*p==',') {
    if(*p = delimiter){
      *p++ = '\0';
      if (i<NBVALS)
         splitedString[i++] = p;
    } else
      p++;
  }
  while(i<NBVALS)
    splitedString[i++] = p;
}

Many thank for your help!!!!

+CMGR: "REC READ","55555","","13/09/08,14:25:34+08"

If this is what you want to split up, then look into strtok(), it is a very useful function.

Hello, as I wrote, below I tried it.
What I need is to remove the " :slight_smile:

it print this:

0:+CMGR: "REC READ",
1:"55555",
2:"",
3:"13/09/08,
4:14:25:34+08"

And I want that:

0:+CMGR: "REC READ"
1:55555
2:
3:13/09/08
4:14:25:34+08

Cheers

So use an IF ELSE statement and go through each character individually. If the character is a " then skip over it, otherwise print the rest.
