[0173] In order to allow large groups of customers to easily access their services, service providers 405 wish to be able to accept data in a variety of XML formats (i.e., such as the one shown in Example 1), and then have that data automatically mapped to In a similar data structure within the service provider 405 native programming language.

Also in FIG. 8 , XML schemas developed by, for example, a product vendor group (e.g., as illustrated in Example 3) are used in order to verify that the XML processing code is correct and that the resulting Whether XML conforms to the specification of the vendor group. At compile time, the compiler uses this pattern specification to detect errors in the code that would otherwise not appear until run time, thereby reducing the number of errors in the runtime system. At runtime, the code uses the validate() function to dete...

Abstract

A system is provided for manipulating data representation language based - objects in a native programming language environment. In one embodiment, the system is used to map data objects of the data representation language to corresponding objects within the native programming language and vice versa. In one embodiment, the system is equipped to receive a mapping definition mapping selected elements of a data representation language, such as an XML data structure, to selected objects of a programming language, such as ECMAScript. The system is further equipped to determine whether the mapping definition comprises one or more definitional statements expressed with data representation language oriented language elements of a programming language. Further, the system is equipped to process the mapping definition statements comprising data representation language oriented language elements of the programming language, in accordance with syntactical and semantic definitions of the data representation language oriented language elements (100, 102, 104, 105, 106).

Description

[0001] related application [0002] This patent application is a continuation-in-part of nonprovisional application 09 / 898,898, filed July 2, 2001, and claims priority to provisional application 60 / 302,892, also filed July 2,2001. field of invention [0003] The present invention relates to the field of programming languages. More specifically, the present invention relates to a method for manipulating data representation language based objects in a native programming language environment. Background technique [0004] XML is rapidly emerging as the de facto standard for transferring data structures between software applications and web services. Although most software applications and web services are written in modern programming languages, such as Java or C++, none of these programming languages ​​provide native support for representing and manipulating XML. Consequently, programmers have had to develop or adopt external packages for representing and manipulating XML wi...
