An apparatus comprises a computer accessible medium encoded with a plurality of instructions which, when executed, compile a stylesheet into one or more data structures, and a hardware circuit coupled to receive the data structures and a document. The hardware circuit is configured to perform at least a portion of transforming the document as specified in the stylesheet using the data structures.

Hardware/software partition for high performance structured data transformation

An apparatus comprises a stylesheet compiler and a document processor. The stylesheet compiler is configured to identify expressions in a stylesheet and is configured to generate one or more expression trees representing the expressions. Expressions having one or more common nodes are represented as children of a subtree that represents the common nodes. Coupled to receive a document and the expression tree, the document processor is configured to evaluate the expressions represented in the one or more expression trees against the document.

Expression grouping and evaluation

In various embodiments, an appliance may be used to implement various functions. In some embodiments, an appliance may be used with a DBMS server. The appliance may generate a request, and the DBMS server may generate a result. The appliance may transform the result to a different format for return to a requestor corresponding to the request. In still other embodiments, the appliance may be used with a computer system configured to execute other backend applications such as content management systems, filesystems, etc. In other embodiments, the appliance may receive first output data from a first server of a plurality of servers that is to be supplied as first input data to a second server of the plurality of servers. The appliance may be configured to transform the first output data to a first markup language format and to transform the first markup language format to the second format.

Applications of an appliance in a data center

Numerous embodiments of structured data transformation are disclosed. Some embodiments include characterizing at least a portion of an expression in a stylesheet as evaluatable at a phase wherein the phase is one of a compile phase, a parse phase, or a transformation phase of applying the stylesheet to a document to transform the document in a document transformation appliance, applying at least a portion of the expression to the document in the phase determined in the characterizing, combining results from applying the at least a portion of the expression and from applying other expressions to the document to generate a transformed document, and outputting the transformed document or saving the transformed document to memory.
