functx:is-node-in-sequence
Whether an XML node is in a sequence, based on node identity
Description
The functx:is-node-in-sequence function returns a boolean value indicating whether or not a node is in the specified sequence, based on node identity. It does not identify nodes that are descendants of nodes in the sequence; see functx:is-node-among-descendants for that purpose. If $node or $seq is the empty sequence, it returns false.
Nodes are identified based on node identity, not their contents. For a similar function based on the contents of a node, see functx:is-node-in-sequence-deep-equal.
