You can filter XML data in a session by creating an XPath query predicate on a view row or column beneath the view row in an XML hierarchy. When you create an XPath query predicate, the XML Editor adds the XPath query predicate to the view row XPath.

When you create an XPath query predicate in the XML Editor, the XML Editor provides elements, attributes, operators, and functions to build the query. You can select the components, enter components, or copy components into a query. The XML Editor validates each query that you create.

You can query the value of an element or attribute, or you can verify that an element or attribute exists.
