xdmp.subbinary

xdmp.subbinary(
   source as binary(),
   starting-location as Number,
   [length as Number]
) as binary()

Summary

Returns a binary node made up of a subset of the given binary node.

Usage Notes

Usage is exactly like fn:substring except that it applies to a binary node rather than a string.

Example

var node = new NodeBuilder();
var bin = node.addBinary( "DEADBEEF" ).toNode();
xdmp.describe(fn.data(xdmp.subbinary(bin, 3, 2)));
  => xs:hexBinary("BEEF")
