xf:base64Binary

Converts $string-var (a string) to a base64 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 base64Binary 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

Note: I took this from the test cases, is there a better example?

Simple

Invoking base64Binary("AaaaAAAA") returns the base64 binary value of AaaaAAAA, as shown in the following example query:

<result>{xf:base64Binary("AaaaAAAA")}</result> 

The preceding query generates the following result:

<result>AaaaAAAA</result>
