    摘要: An apparatus comprises a parse circuit and an expression processor. Coupled to receive a document, the parse circuit is configured to parse the document and generate events corresponding to the parsing. Coupled to receive the events from the parse circuit, the expression processor is configured to apply nodes identified by the events to one or more expression trees derived from a plurality of expressions in a stylesheet. The expression processor identifies nodes that satisfy the expressions represented in the one or more expression trees as a result of applying the nodes to the one or more expression trees. A method is contemplated. Each expression in a stylesheet is characterized as evaluatable at one of a plurality of phases of applying the stylesheet to a document in a document transformation appliance. Each expression is applied to the document in the one of the plurality of phases determined in the characterizing.

    摘要: 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.
