A method and system for allowing clients to retrieve data from data sources that do not necessarily support the same protocols and formats as the clients. The clients issue service requests. A pre-processor responds to the requests by generating XML-structured request objects with unresolved links to the data sources that have information required by the clients. An XML processor resolves the links by issuing requests through one or more gateways. The gateways convert the responses received from the data sources into XML, which the XML processor uses to create XML composite response documents. A post-processor filters the XML response documents, and applies XSL stylesheets to transform the XML composite response documents into client-specific responses that conform to the format required by the clients. The client-specific responses are then sent to the clients.

A method, system, and computer program product for selectively encrypting one or more elements of a document using style sheet processing. Disclosed is a policy-driven augmented style sheet processor (e.g. an Extensible Stylesheet Language, or “XSL”, processor) that creates a selectively-encrypted document (e.g. an Extensible Markup Language, or “XML”, document) carrying key-distribution material, such that by using an augmented document processor (e.g. an augmented XML processing engine), an agent can recover only the information elements for which it is authorized. The Document Type Definition (DTD) or schema associated with a document is modified, such that the DTD or schema specifies a reference to stored security policy to be applied to document elements. Each document element may specify a different security policy, such that the different elements of a single document can be encrypted differently (and, some elements may remain unencrypted). The key distribution material enables a document to be encrypted for decryption by an audience that is unknown at the time of document creation, and enables access to the distinct elements of a single encrypted document to be controlled for multiple users and / or groups of users. In this manner, group collaboration is improved by giving more people easier access to information for which they are authorized, while protecting sensitive data from unauthorized agents. A key recovery technique is also defined, whereby the entire document can be decrypted by an authorized agent regardless of how the different elements were originally encrypted and the access protections which were applied to those elements.

A system and methods are provided for operating and building graphically XML processing programs, guiding the user in development of the program, preventing and detecting development errors as the program is being designed, ensuring that the program is valid, i.e. satisfies required input and output constraints at all times, i.e. from the time it is developed to when it is deployed in a production environment, ensuring the automated change management if the internal logic of the Web service, or data sources called by the service or the schema that underlies the Web service are modified. The system includes a graphical XML Programming system where XML processing programs are built and represented in a graphical fashion, a real-time metadata computation and visualization method for each selected execution point in the visual program that provides guided programming, error prevention and detection, and change impact analysis and change management, and, an automated execution path exploration method that enables overall program validation and error identification. The system and methods allow a user to reduce by at least a factor of 2 the costs of development and maintenance of reliable XML processing programs such as Web Services.

A system for a context-independent framework for management and execution of XML processing tasks is provided. The XML processing tasks are executed by a module, herein referred to as the XSA Engine, according to a predefined set of instructions provided as electronic documents written in a special purpose, XML-based, programming language. The instruction sets contain references to, and control the execution of, instances of three classes of processing modules, which independently accomplish an XML processing subtask and jointly accomplish an XML processing task. The framework is decoupled from any specific execution context, meaning that standardized XML processing can be applied in almost any desired application. The special purpose programming language enhances productivity for development of XML processing tasks as compared to using general purpose programming languages, and diminishes the need for writing custom code to link different types of XML processing subtasks to accomplish an XML processing task.

A document assembly or document automation system includes an assembler for generating an instance document on the basis of a source document and one or more logic source documents referenced by the source document. The source document and logic source documents are XML documents including at least one XML processing instruction. The source document and logic source documents are valid with respect to XML schema. The system generates an instance document in HTML, PDF or RTF format by resolving variables in the source document and / or logic sources using one or more data sources. This may involve performing one or more interview rounds with a user of the system, access to a database, and / or evaluation of a function defined in one of the documents. The system includes an editor for creating and maintaining source documents and logic source documents whilst maintaining their validity with respect to the appropriate XML schema.

Broad XML support is obtained through use of a set of streaming parser APIs. An application or client needing access to an XML document can contact an XML parser, XML processor, or XML reader in order to gain access to the document. The XML processor selects and instantiates a streaming parser API that is appropriate for the XML document and the client or application. Streaming parser APIs include raw streaming parser APIs, non-validating streaming parser APIs, and validating streaming parser APIs. The XML parser can then provide a variety of types of access to the application or client that does not require the entire document to be read into memory, including providing an XML stream, pulling XML information, and skipping unwanted XML from the document.

A method and apparatus for accelerating processing of a structured document. A hardware XML accelerator includes one or more processors (e.g., CMT processors), one or more hardware XML parser units, one or more cryptographic units and various interfaces (e.g., to memory, a network, a communication bus). An XML document may be processed in its entirety or may be parsed in segments (e.g., as it is received). A parser unit parses a document or segment character by character, validates characters, assembles tokens from the document, extracts data, generates token headers (to describe tokens and data) and forwards the token headers and data for consumption by an application. A cryptographic unit may enforce web security, XML security or some other security scheme, by providing encryption / decryption functionality, computing digital signatures, etc. Software processing, bus utilization and latencies (e.g., memory, bus) are greatly reduced, thereby providing significantly improved XML processing and security processing throughput.

Information represented in text-based markup languages, such as XML, is often a large, highly nested structure corresponding to complex patterns of metadata and / or data. Parsing such data streams via conventional software mechanisms rapidly exhibits degrading performance as the size, or volume, of data increases. Further, such do not perform dynamic modification to the output in response to feedback based on the data being parsed. An adaptive XML processing hardware apparatus processes an XML document in a manner suited to the invoking application, and processes the incoming XML into an optimal structure based on the type of data and a set of rules relating the type of the data to the output format. It also dynamically augments the output information stream based on the data, at the option of the invoking system. The generated output may take a tree form, adaptable for efficient traversal of the hierarchical structure represented by the input XML, or may involve an attribute approach, in which the XML takes the from of a stream of fixed length cells containing optimized representations of input data, or may take a combination of the two approaches, based on configuration and XML input stream.

Disclosed is an XML database duplicating apparatus and method capable of providing an effective application service without interruption at a low cost in the diverse Internet environments by copying an XML document of a database system mounting an XML processing technique to another remote server. When the XML document stored in a database of the original server is copied to databases of copied servers, the structure and attribute information included in the XML document are maintained as they are, and thus the respective copied servers can support the searches based on the contents and the attribute provided by an XML query language and disperse users' queries concentrated to the original server to the respective copied servers, so that the service request for application programs can be processed.

A system and method for using Extensible Markup Language (XML) as a scripting language to drive testing of a software program. XML is used to define a markup language in a script that provides commands that are interpreted by a test control processor. The test control processor includes an XML processor for processing the script. Using the script, the test control processor submits instructions to a software program and extracts the behavior of the software program. The software program behavior is tested by submitting multiple sets of instructions and comparing the results. Information regarding the software program behavior and test results is written to an output log file by the test control processor.

The DEC of the sensor data converter defines a structure of the sensor data using a schema of the XML and converts the sensor data format to the XML format at the same time.

A system for storing and dynamically updating data represented in the Extensible Markup Language (XML) which separates the data values in at least some of the elements of an XML document and places those data values in relational database tables where they may be processed using conventional RDBMS techniques. The hierarchical structure of the XML document is saved separately in an XML skeleton object from which element data other than primary key values has been removed. The XML documents document type definition (DTD) is stored, along with additional property data used the RDBMS, in an XML Definition object. The additional property information includes the identification of primary key data values which are used to link the structural definition data to the value data stored in the tables, the designation of data types used for more efficient storage of data from predetermined XML elements, the designation of selected element data for indexing and for column storage, and the designation or relational integrity constraints which help insure that logically connected data is not inappropriately deleted or updated. The XML data as stored in the relational tables can be retrieved as a complete XML document, or selected XML elements can be retrieved by themselves, by merging the table data into the XML skeleton.

The invention discloses an XML metadata objectification analytic method, a data element in XML data is defined according to an XML Schema. The method comprises the following steps: a data object which is consistent with the structure of the data element is defined, wherein the incidence relations of the data object and the data element are consistent; the XML data are read and analyzed; the data object corresponding to the XML data is instantiated, and the data object of the same structure as the XML data is formed. The XML metadata objectification analytic method and a system predefine the XML Schema of the structure of the XML data, the XML Schema defines the attribute name, type, default, incidence relation of father and son elements and the like of each element, and the embodiment of the invention uses the data directly to establish a corresponding Java type, thus solving the problems in the existing XML processing mode.

An XML processing model enables applications that use an XML stream to perform metadata-based or other processing of data during a data validation operation while preserving a streaming processing model. For example, while an XML node is being validated, requests can be received regarding the status of the validation and any processing that may be required with the node in order to conform it to requirements of an external application. A validator exposes public APIs that allow such validation-time requests from an event handler that is associated with an external application and that is registered with the XML stream. Messages that identify schema annotation definitions are provided to an external application to direct the type of processing to be performed on nodes at application runtime. Thus, applications can process a node according to the annotation definition concurrently with validation of the given node by the validator.

Described embodiments provide a method of processing data packets received at a network interface of a host device. The network interface detects whether a received data packet is an XML packet. If the data packet is an XML packet, the network interface provides the XML packet to an XML accelerator that performs one or more acceleration operations on the XML packet. The XML accelerator provides processed XML data to a buffer memory and provides an indication to a processor of the host device, the indication including a location of the processed XML data in the buffer. The steps of providing the XML packet to the XML accelerator and performing one or more acceleration operations are performed before an XML data stream corresponding to the XML packet is TCP / IP terminated. If the received data packet is not an XML packet, the network interface provides the data packet to a TCP / IP stack.
