Web Content Extraction via XHTML Class Attributes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for packaging web content for reuse are inefficient, as they lack standardized mechanisms for identifying and extracting web content from module manifests, making it difficult to import and embed web content into web pages while maintaining its functionality and associated metadata.
Innovation Solution
The use of microformat specifications within XHTML-based module manifests to identify and package web content, allowing for the extraction and embedding of web content into web pages by designating specific class attributes for view containers, module containers, and meta-data elements, enabling the importation engine to parse and render the content effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If web content is packaged within a module manifest using traditional methods, then the web content can be stored and organized, but the extraction and embedding process becomes complex and inefficient due to lack of standardized identification mechanisms
Solution Approach 1:
The module manifest is segmented into distinct standardized elements: view containers for content, module containers for packaging, and meta-data elements for information. This segmentation allows the importation engine to systematically parse and extract specific components without processing the entire manifest, thereby improving extraction efficiency and reducing processing complexity.
Solution Approach 2:
The patent introduces standardized parameters (class attributes with specific values like 'view container', 'module container') that transform the extraction process from unstructured parsing to structured parameter-based identification. This parameter standardization enables efficient pattern matching and extraction operations, directly resolving the contradiction between extraction efficiency and process complexity.
2Measurement precision
If web content is packaged without standardized identification attributes, then the packaging process is simpler, but the ability to reliably identify and extract specific content elements deteriorates
Solution Approach 1:
View containers and module containers are pre-tagged with standardized class attributes during the packaging phase. This preliminary action of adding identification markers during packaging enables accurate and reliable identification during extraction, resolving the contradiction between identification accuracy and packaging simplicity by making the accuracy achievable through standard attribute assignment.
3Loss of information
If microformat specifications are used to package web content, then the semantic meaning and metadata are preserved, but the parsing and processing requirements increase
Solution Approach 1:
The importation engine extracts only the necessary standardized elements (view containers, module containers, and their associated meta-data) from the module manifest using pattern matching based on standardized class attributes. This targeted extraction approach preserves all semantic meaning and metadata while avoiding the complexity of parsing the entire manifest structure, thus resolving the contradiction between information preservation and processing requirements.

AI summary
A request to import web content that is packaged within a module manifest into a web page is received. In response to receiving the request to import the web content into the web page, the module manifest is accessed. A view container that includes the web content is identified within the accessed module manifest. The view container is a standard XHTML structural element that has a class attribute that designates the standard XHTML structural element as the view container. The web content is extracted from the view container and embedded in the web page.
