| Abstract | The eXtensible Markup Language (XML) is a universal format for structured documents and data over the web. The Hypertext Markup Language (HTML) format describes only the format of the data, and therefore, programs cannot understand the structure of such data. On the other hand, XML provides flexibility in the representation of the structured documents and data. The World Wide Web Consortium (W3C) introduced XML to complement HTML, for data exchange over the web. Bray et al (2008) explained the most recent version of the XML language recommendation. XML is a powerful tool, meant to deal with the current structure of document information processing. It is a cross-platform Internet environment technology, which is dependent on the content. XML documents (marked-up documents) are self-describing. Therefore, it is possible for programs to interpret the meaning of the data, which are received, filter the document based on its content, and restructure it to suit the application's needs. XML documents provide a platform independent means to describe data, and hence, they can transport data from one platform to another. XML is a simplified subset of the Standard Generalized Markup Language (SGML), the international standard metalanguage for text markup 2 systems. XML is designed to improve the functionality of the web, by providing more flexible and adaptable information identification. It is called extensible because it allows the user to create his/her own tags that describe the data, unlike HTML that has pre-defined tags to format the data on the web. Although XML takes more space than the binary data, XML is extremely simple and easy to master and use. These features make XML the first choice for the exchange of information between the Simple Object Access Protocol (SOAP) and web services. Since XML is structured data, it is suitable for a structured data transmission network. Therefore, in recent years, XML applications have been growing. Security has always been of importance to ensure data protection, transactions' integrity, and maintain information privacy and confidentiality. One of the most challenging problems in managing large, distributed, and heterogeneous networked systems, is the ability to specify and enforce security policies between parties, and ensure access to services and resources. The infrastructure over the Internet has turned out to be difficult, due to system heterogeneity and conflicting security requirements. Nowadays, the main requirement of Internet-wide security standards, is applying the security to the content created, using XML. XML has been adopted widely … |
