Info

Subtree Filtering Subtree filter expressions select XML subtrees to include in get and get-config responses (XPath expressions can be used as well if the :xpath capability is supported). ⊲ namespace selection (wildcarding) A non-null namespace of a node in a subtree filter matches the node in the given namespace. A null namespace acts as a wildcard. ⊲ attribute match expressions The set of XML attributes present in any type of filter node form an “attribute match expression”; the selected data must have matching values for every attribute of an attribute match expression. 34 / 90
Subtree Filtering (cont.) ⊲ containment nodes For each containment node of subtree filter, all data model instances must exactly match the specified namespaces, element hierarchy, and any attribute match expressions. ⊲ selection nodes An empty leaf node of a filter selects the specified subtree(s) and it suppresses the automatic selection of the entire set of sibling nodes. ⊲ content match nodes A leaf node of a filter containing simple content selects some or all of its sibling nodes. 35 / 90
