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 |
---|---|---|---|---|
as | string | optional[a] | _parsehexstring | Name of output field. |

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

parseHexString()
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)
