Parses the input from hex encoded bytes, decoding the resulting bytes as a
string using the selected character set. If the input fields has a prefix
(other than 0x and 16#) then use regex()
or
replace()
to remove the prefix before using
parseHexString
. Any non-hex characters in
the input are ignored — the decoding attempts to decode all chars in
the field that match 0-9
or
A-F
. Case is ignored.
Parameter | Type | Required | Default Value | Description |
---|---|---|---|---|

charset | string | optional[a] | UTF-8 | The charset to use when transforming bytes to string. |
Valid Values | ||||

field [b] | string | required | Specifies the field containing the hex string to use as input. | |

Examples
Parses the string 48656c6c6f576f726c64
from the field named foo into
the field text, getting the value Helloworld:
foo := 48656c6c6f576f726c64
| parseHexString(foo, as=text, charset="ISO-8859-1")
Parses the string 0x4 865 6c6c6f576f726c6420
plus F 0 9 F 9 8 8 0
from the field named
hex into the field text, using
UTF-8
and getting the value Helloworld
😀 where the smiley is the result of decoding the trailing digits:
hex := "0x4 865 6c6c6f576f726c6420 plus F 0 9 F 9 8 8 0"
| text := parseHexString(hex)
