WebSQL is a SQL-like query language for extracting information from the web. Its capabilities for performing navigation of web hypertexts makes it a useful tool for automating several web-related tasks that require the systematic processing of either all the links in a page, all the pages that can be reached from a given URL through paths that match a pattern, or a combination of both. WebSQL also provides transparent access to index servers that can be queried via the Common Gateway Interface. By 5ai9.com-->
