functx:index-of-deep-equal-node

The position of a node in a sequence, based on contents and attributes

Description

The functx:index-of-deep-equal-node function returns one or more integers representing the position of an XML node within a sequence of nodes. Rather than being based on node identity, it is based on the equality of the name and content of the nodes, as defined by the built-in fn:deep-equal function. If $nodes does not contain a match, the function returns the empty sequence.
