"The Extensible Markup Language (XML) is a document processing standard proposed by the World Wide Web Consortium (W3C) ... many expect XML and its sibling technologies to replace HTML as the markup language of choice for dynamically generated content, including nonstatic web pages.
While many XML applications currently support Cascading Style Sheets (CSS), a more extensible stylesheet specification exists called the Extensible Stylesheet Language (XSL). By using XSL, you ensure that your XML documents are formatted the same no matter which application or platform they appear on." (XML Pocket reference - O'Reilly) Westhawk use Oracle's XSQL/XSLT as a way of integrating data input and extraction over the web. XSQL is an XML wrapper that surrounds the SQL (Structured Query Language) enabling the queried data to be returned in XML format. XSLT defines the industry-standard method of using XSL (Extensible Stylesheet Language) to transform the platform- neutral query result into XML, HTML or plain text. Westhawk use XSQL/XSLT because the combined power of existing standards such as SQL, XML and XSL with the transport mechanism HTTP, enables us to develop solutions that receive, access and respond to web-based information requests from any end user device on the Web. At the same time, these processes make it possible to practise the recommended data-view-model approach, by cleanly separating the queried content from the way the data will be formatted and presented to the requester. |
