import chilkat2

success = False

sb = chilkat2.StringBuilder()
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.
removeFlag = False
marker = "."
substr = sb.GetBefore(marker,removeFlag)
print("substr = " + substr)
print("sb contains: " + sb.GetAsString())

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

removeFlag = True
substr = sb.GetBefore(marker,removeFlag)
print("substr = " + substr)
print("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)
    print("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:
