xf:hexBinary

Converts $string-var (a string) to a hex-encoded arbitrary binary data.

If the value of $string-var is the empty sequence, the following error is displayed in the mapper:

Error occured while executing XQuery: Error loading the XQuery or XSLT for this method: Type error in function hexBinary invocation: expected type [string@http://www.w3.org/2001/XMLSchema], given type empty

The empty sequence is a sequence containing zero items (), which is similar to null in SQL.

Examples

Simple

Invoking hexBinary("0FD7") returns the hex-encoded binary value of 0FD7, as shown in the following example query:

<result>{xf:hexBinary("0FD7")}</result> 

The preceding query generates the following result:

<result>0FD7</result> 

Note: The hex-encoded binary value of 0FD7 is equivalent to the decimal value of 4055 and the binary value of 111111010111.
