  • COMPLEX PATH-BASED QUERY EXECUTION
    Publication number: 20110131200
    Abstract: Systems, methods, computer program product embodiments are provided for executing a function in a path-based query when extracting data from a markup language document for return as a relational table, the markup language document organized hierarchically into nodes. An embodiment includes receiving a path-based query including a complex row pattern and column definition, forming multiple sets of nodes based on a simplified row pattern and column definition, determining ancestor-descendent pairings for the nodes in the column definition set, and utilizing the ancestor-descendent pairings with the simplified row pattern to return a relational table satisfying the complex path-based query. An embodiment further includes extensible markup language (XML) as the markup language, and an XPath query expression as the complex path-based query.
