fn.documentUri

fn.documentUri(
   $arg as Node?
) as String?

Summary

Returns the value of the document-uri property for the specified node. If the node is a document node, then the value returned is the URI of the document. If the node is not a document node, then fn:document-uri returns the empty sequence.

Parameters
$arg The node whose document-uri is to be returned.

Usage Notes

fn:document-uri will only return the URI of a document when a document node is passed into it. If you want to return the URI of a node that is not a document node, but has a document node ancestor, use fn:base-uri or xdmp:node-uri.

Example

var x = cts.doc("/bar.json");
fn.documentUri(x);

=> "/bar.json"
