StringBuilder GetBefore

The GetBefore method was added in Chilkat v9.5.0.77

var success = false;

var sb = new CkStringBuilder();
success = sb.Append("www.chilkatsoft.com");

// The GetBefore method returns the contents of the string up to but not including
// the marker string.  If the remove flag is true, then both the returned string AND
// the marker are removed.
var removeFlag = false;
var marker = ".";
var substr = sb.GetBefore(marker,removeFlag);
console.log("substr = " + substr);
console.log("sb contains: " + sb.GetAsString());

// Output:
// substr = www
// sb contains: www.chilkatsoft.com

removeFlag = true;
substr = sb.GetBefore(marker,removeFlag);
console.log("substr = " + substr);
console.log("sb contains: " + sb.GetAsString());

// Output:
// substr = www
// sb contains: chilkatsoft.com

// If the marker is not found, and the removeFlag is true,
// then the entire string is returned and the sb is cleared.
// For example:
sb.Clear();
sb.Append("111--222--333--444");
marker = "--";
removeFlag = true;
while ((sb.Length > 0)) {
    substr = sb.GetBefore(marker,removeFlag);
    console.log("substr = " + substr + ", sb contains: " + sb.GetAsString());
}

// Output is:
// substr = 111, sb contains: 222--333--444
// substr = 222, sb contains: 333--444
// substr = 333, sb contains: 444
// substr = 444, sb contains:
