...XML and HTML have differences that can determine one from the other. XML is used in many ways but there are three ways where XML is used more than others are. XML also has standards that will be discussed. This presents many questions concerning XML and HTML and their differences. According to Walsh XML is a markup language that contains structured information. The information contains words and pictures. With some kind of indication of what role those words and pictures play. Almost every document there is has some sort of structure. A markup language is a mechanism that identifies structures within a document. The XML defines a way to add markup to documents (Norman Walsh, 2010). A number of related specifications arise when defining XML. XML (Extensible Markup Language) defines the syntax of XML. XPointer (XML Pointer Language and XLink) XML Language defines a standard way to represent links between resources. XML has mechanisms for links between several resources and links for read-only resources. XSL (Extensible Style Language defines the standard style sheet language for XML (Norman Marsh, 2010). HTML (Hypertext Markup Language) is a markup language that is used for the developing web pages. HTML is a way to show the structure of text-based information in a document by setting certain text headings, paragraphs, lists, and to replace that text with forms that interact, images, and other objects as well (PRLog, 2008). Even though they are very similar...

...XML, or extensible Markup Language, is a language based on web standards use by various communities and products. Similar to HyperText Markup Language, or HTML, XML is more concerned with data display than the presentation (Robbins, 2006). XML provides a unique structure that enables developers to define their own tags and attributes for elements. Defining such a unique set tags gives their intended audience data in a specific information format. Identifying difference of XML and HTML, examining XML standards, and providing XML examples will explain why XML is an important data exchange markup language standard. In order to understand XML it is important to understand HTML and differences between the two languages. The core technology for web page design is HTML. This language provides a non-programming language that marks up a page through use of tags to present objects. Angle bracket with keywords inside in an open and closing format provides instructions for a browser to interpret to display objects. Not all objects of HTML actually have open and close tags. Examples of standard HTML tags include “ ”, “” objects which produce a link and text input. Attributes are associated with objects allow displaying variations to the rendered objects. A browser is used to generate a page based on the objects that are displayed in order. Presentation of content employs a static method. Constant updates to pages are an inherent setback for using HTML. Additional technologies...

...XML / XSLT What is XML, and why has it gained so much momentum? XML, or Extensible Markup Language, is an excellent way of representing data in a structured format. The most popular application of XML is for data-exchange. Like HTML, XML is also a textual, tag-based "markup" language. However, unlike HTML, which has a fixed set of tags and focuses on "presentation", XML does not have any fixed set of tags, and XML is all about "data". It is possible to create our own tags, and write data inside these tags in an XML document. The XML data is structured in a hierarchical format, and there are many "parsers" available that allow easily getting to the data values. In addition to data-exchange, XML is being used for various other purposes, such as content management, XML-based configuration files, eBusiness, document publishing, application integration, and most notably XML-based messaging or Web services. Some of the reasons behind XML's success include: • The ability to define and use our own tags makes XML "extensible", and self-describing. • XML's textual nature makes it highly portable allowing us to send and receive data from one platform to the other without any issues (such as encoding). • The availability of many free XML parsers and processors, makes it really easy to create, read, and manage XML documents. • As mentioned earlier, XML is all about data. Separating "presentation" from the actual "content" has many benefits, including the flexibility...

... What means XSLT? XSL (eXtensible Stylesheet Language) consists of • XSL-T (Transformation) – primarily designed for transforming the structure of an XML document – W3C Specification: http://www.w3c.org/TR/xslt • XSL-FO (Formating Objects) – designed for formatting XML documents – W3C Specification: http://www.w3c.org/TR/xsl XSLT origin: Document Style Semantics and Specification Language (DSSSL, pron. Dissel). Why Transform XML? XML is a success because it is designed: • for separation between content and presentation (XML is a generic markup language) • as a format for electronical data interchange(EDI) between computer programs • as human readable/writable format Transforming XML is not only desirable, but necessary. XSLT is an attempt to fulfill this need, by supporting • publishing data (not necessarily XML). • conversion between two proprietary formats (not necessarily XML). Publishing XML data Data Conversion How XML data can be transformed using XSLT? (1/3) 1 a conversion of XML data into a tree structure, e.g. using an XML parser conformant to – Document Object Model (DOM) http://www.w3.org/DOM/ – Simple Api for XML (SAX) http://www.megginson.com/SAX/sax.html Tree structure XML fragment This is an example para XML Parser DOM/SAX This is an em example How XML data can be transformed using XSLT?

...10 XML Interview questions and answers for Java Programmer by Javin Paul on January 27th, 2013 | Filed in: Core Java Tags: XML XML Interview questions are very popular in various programming job interviews, including Java interviews for web developer. XML is a matured technology and often used as standard for transporting data from one platform other. XML Interview questions contains questions from various XML technologies like XSLT which is used to transform XML files, XPATH, XQuery and fundamentals of XML e.g. DTD or Schema. In this article we will see 10 frequently asked XML Interview questions and answersfrom above topics. These questions are mostly asked in various Java interviews but they are equally useful in other programming interviews like C, C++, Scala or any other programming language. Since XML is not tied with any programming language and like SQL its one of the desired skill in programmer, it make sense to practice some XML questions before appearing in any technical job interview. XML Interview Questions and Answers Here is my list of some common and frequently asked Interview questions on XML technologies.

...Google and Yahoo! can be classified under the ‘Portal’ B2C business model, as both sites offer and integrate a wide package of content including: social network services, news, e-mail, and the ability to search content. The major reason web surfers use either site is simply because these services offered to the public are free. Individuals are permitted to utilize these services free of charge because both companies receive revenues through advertisements. Google for example will only receive payment from their advertisers once a searcher “clicks” on their ad. Both companies also realize the same market opportunity and compete for the same market share with other organizations including: Bing, Ask, and AOL. One of the major distinctions between Yahoo! and Google is the competitive advantage both companies offer to the public. Although both provide a wide range of features, Google maintains their own algorithms in order to achieve the most accurate search results whereas Yahoo! concentrates more on other services they offer such as Yahoo! local or Yahoo! answers allowing them to better compete with Google for market share. 2. One of the common difficulties a company is confronted with when expanding the reach of their market is growing too quickly. Physical space may become too small, and will no longer be sufficient in supplying customer demand. It also becomes easy for a company to lose track of important business operations if expansion happens too quickly; therefore, the...

...improvements that we made as we improved the functionality of Kudler’s website. In order to accomplish this task, we split the assignment into seven subtasks or areas of concentration. These seven subtasks are as follows: Identify basic XHTML tags and attributes used in your prototype; Compare how different web browsers display our prototype, what differences we noticed in the web browsers and what caused them; Describe how Cascading Style Sheets (CSS) were used to format the site’s web content; Explain how JavaScript® arrays, loops, and conditional statements were used in our prototype; Identify professional web development standards we used in the development of the prototype; Explain how Metadata might promote this website; and Identify the process we will use to publish, maintain, and redesign this website. As we began to improve Kudler’s website, we started with the development of a prototype and following our seven subtasks, brought us to identifying basic XHTML tags and attributes within the prototype. In this prototype, there are several different types of simple XHTML (Extensible Hyper Text Markup Language) tags and attributes being used. While learning XHTML, we discovered that these tags are similar to HTML and found that it was as simple as understanding HTML. Tags, simply put,...
