19.3.2 Extracting characters

This subsection gives an example of extracting only alphanumeric characters from the character string 0123-4567-89AB-CDEF and outputs the results to RecDFile.log.

Organization of this subsection

(1) Coding example

strStrName = "0123-4567-89AB-CDEF";    // Original string
strSearchStr = "-";                    // Search string
nStartPos = 0;
while(TRUE)
  // Gets the length of string to be extracted.
  nLength = AIT_FindSubStr(strStrName, strSearchStr, nStartPos);
  if (nLength == -1)
    // Sets the string to be extracted last.
    strSubString = strStrName;
    AIT_LogMessage("strSubString = " + strSubString); 
    // Ends extraction of strings.
    break;
  else
    // Extracts a string.
    if (!AIT_GetSubStr(strSubString, strStrName, nStartPos, nLength))
      AIT_LogMessage("AIT_GetSubStr failed");
      break;
    else
      AIT_LogMessage("strSubString = " + strSubString);
    endif;
    // Deletes the extracted string from the original string.
    strStrName = AIT_StrLTrim(strStrName, strSubString);
    strStrName = AIT_StrLTrim(strStrName, strSearchStr);
    strSubString = "";
  endif;
loop;
// Value of strStrName changes from that before processing.
AIT_LogMessage("strStrName = " + strStrName);
