Hi there,
I am running below script succesfully in the PYTHON Creator but i can't get it to expose a created value into and attrribute. the script creates a 3 digit number in ICP_GEN_ICP based on a parameter I provide for CheckICP, but it won't get exposed. i need to know how I can assign this value to an attribute and use it in an XML templater. thanks!
ps i am new to coding ( both FME and Python)
script:
D = int('0x180f', 0)
H100 = int('0x100', 0)
H1000 = int('0x1000', 0)
HFFFF = int('0xffff', 0)
def Asc(bytes_obj):
'''Get the int value of a char'''
if type(bytes_obj) == bytes:
return bytes_obj[0]
else:
return ord(bytes_obj[0])
def Mid(string, integer, integer2):
'''Select a substring from a string'''
integer = integer - 1
return string[integer : integer+integer2]
def gen_crc(icp_number):
""" Generate a checksum for an ICP"""
R = int('0', 0)
CheckICP = FME_MacroValues['icp_number']
ICP_GEN_CRC = ""
IChar = 0
if len(CheckICP.strip()) < 12:
ICP_GEN_CRC = "Insufficient Data"
else:
CheckICP = CheckICP[:12] + "\\0\\0\\0"
#print('CheckICP: ' + str(CheckICP))
for I in range(0,108):
#print(I)
if I%8 == 0:
IChar = Asc(Mid(CheckICP, int((I/8)+1), 1))
#print('IChar: ' + str(IChar))
IChar = IChar * 2
#print('IChar: ' + str(IChar))
R = R * 2
#print('R: ' + str(R))
if int((IChar & H100) / 256.0) == 1:
R = R + 1
if (R & H1000) > 0:
R = R ^ D
R = R & HFFFF
#print('R: ' + str(R))
CheckICP = ("000" + format(R,'x'))[-3:]
#print('CheckICP: ' + str(CheckICP))
ICP_GEN_CRC = CheckICP.upper()
# below ICP_GEN_CRC should be put in an attribute that i can use in an XML-creator.
print('ICP_GEN_CRC: ' + str(ICP_GEN_CRC))
return ICP_GEN_CRC
i expose ICP_GEN_CRC as output attribute , but it returns empty.
