Abstract
Methods, systems, and apparatus, including computer program products, for processing input data and for defining processing operations to be performed on such data. Input data is processed according to a data parser description associated with the input data format, and output data is generated based on the processing. The data parser description includes a plurality of leaf nodes and a plurality of branch nodes arranged in a tree structure. The leaf nodes each have an associated function. Each of the branch nodes has one or more associated child nodes selected from leaf nodes and other branch nodes. The nodes of the data parser description are evaluated in an order defined by the tree structure. For branch nodes, one or more of the associated child nodes are evaluated; for leaf nodes, the associated function is executed based on data in a current location in the input data.
