A computer-implemented method of creating a schema specific parser for processing Extensible Markup Language (XML) documents can include identifying a plurality of XML processing templates, wherein each of the plurality of XML processing templates performs a specific task of processing an XML document against an XML schema component. An XML schema including a plurality of components can be received. A hierarchy of the plurality of components of the XML schema can be determined. An execution plan specifying a hierarchy of XML processing instructions can be created, wherein each XML processing instruction is associated with an XML processing template from the plurality of XML processing templates. The hierarchy of the XML processing templates can be determined according to the hierarchy of components of the XML schema. The execution plan can be compiled to generate the schema specific parser. The schema specific parser can be output.

Schema specific parser generation

A computer-implemented method of processing an Extensible Markup Language (XML) document can include loading an execution plan into a virtual machine, wherein the execution plan represents an XML schema, and loading an XML document into the virtual machine. XML processing functions available within the virtual machine can be selectively invoked according to the execution plan, wherein the XML processing functions operate upon the XML document. An indication of whether the XML document is valid according to the XML processing functions can be output.

High-level virtual machine for fast XML parsing and validation

A computer-implemented method of creating a schema specific parser for processing Extensible Markup Language (XML) documents can include receiving an XML schema comprising a plurality of components, determining a hierarchy of the plurality of components of the XML schema, and creating an execution plan specifying a hierarchy of XML processing instructions. Each XML processing instruction can be associated with an XML processing function of a virtual machine that performs an XML document processing task. The hierarchy of XML processing instructions can be determined according to the hierarchy of components of the XML schema. An instruction causing the virtual machine to invoke a de-serialization module that extracts at least one item of information from the XML document can be inserted into the execution plan. The execution plan can be compiled into a bytecode version of the execution plan that is interpretable by the virtual machine. The bytecode version of the execution plan can be output.
