functx:is-node-in-sequence-deep-equal

Whether an XML node is in a sequence, based on contents and attributes

Description

The functx:is-node-in-sequence-deep-equal function returns a boolean value indicating whether or not a node has the same contents as a node in a sequence. It determines whether the nodes have the same content using the built-in fn:deep-equal function. If $node or $seq is the empty sequence, it returns false.

For a similar function based on the identity of a node rather than its contents, see functx:is-node-in-sequence.
