fn:collection

fn:collection() → node()*

Function signature

$srcval	xs:string
Result	node() *

XPath 2.0 Specification

Returns the default collection if there is one.

Saxon implements this function by passing a null URI to the registered CollectionURIResolver. The default CollectionURIResolver implementation supplied with the product handles this by returning an empty sequence, but a user-supplied CollectionURIResolver is free to handle this case any way it wishes.

fn:collection(string $srcval) → node()*

Function signature

$srcval	xs:string
Result	node() *

XPath 2.0 Specification

Loads an external collection of nodes identified by the URI of the collection

If a user-defined CollectionURIResolver has been registered, the action of this function is entirely user-defined. A resolver may be registered using the setCollectionResolver() method on the Configuration object, or (in XSLT) using setAttribute() on the TransformerFactory. The CollectionURIResolver may be nominated using the -cr option on the command line.

For details of the behavior of the standard CollectionURIResolver, see Collections.
