What is the difference between html dhtml and xml




















XQuery is a language for finding and extracting elements and attributes from XML documents. Here is an example of a question that XQuery could solve:. XQuery 1. XQuery can be used to:. Extract information to use in a Web Service. Search Web documents for relevant information. See XQuery examples at w3schools. XLink and XPointer.

XLink defines a standard way of creating hyperlinks in XML documents whereas XPointer allows the hyperlinks to point to more specific parts fragments in the XML document. It is a language for creating hyperlinks in XML documents. With XLink, the links can be defined outside of the linked files.

March Currently the browser support for XLink and XPointer is minimal. There is some XLink support in Mozilla 0. Earlier versions of all of these browsers have no XLinks support at all.

See XLink and XPointer examples at w3schools. Other than reducing or eliminates the need for scripting XForms may contain features like calculations and validations of forms. In XForms data and logic is separated from presentation. XForms uses XML to define form data. Forms are an important part of many web applications today. An HTML form makes it possible for web applications to accept input from a user.

XForms provides a richer, more secure, and device independent way of handling web input. We should expect future web solutions to demand the use of XForms-enabled browsers All future browsers should support XForms. XForms 1. See XForms examples at w3schools. The DOM presents an XML document as a tree-structure a node tree , with the elements, attributes, and text defined as nodes.

The Core DOM Level 1 section provides a low-level set of fundamental interfaces that can represent any structured document, as well as defining extended interfaces for representing an XML document. The HTML Level 1 section provides additional, higher-level interfaces that are used with the fundamental interfaces defined in the Core Level 1 section to provide a more convenient view of an HTML document.

It defines the logical structure of documents and the way a document is accessed and manipulated. In the DOM specification, the term "document" is used in the broad sense - increasingly, XML is being used as a way of representing many different kinds of information that may be stored in diverse systems, and much of this would traditionally be seen as data rather than as documents. With the DOM, programmers can build documents, navigate their structure, and add, modify, or delete elements and content.

As a W3C specification, one important objective for the Document Object Model is to provide a standard programming interface that can be used in a wide variety of environments and applications. The DOM is designed to be used with any programming language.

Various other IDLs could have been used. In general, IDLs are designed for specific computing environments. The DOM can be implemented in any computing environment, and does not require the object binding runtimes generally associated with such IDLs.

It is platform and language independent, XML based. It is simple, extensible and also allows you to get around firewalls. It is important for application development to allow Internet communication between programs. As we all know, RPC generates many compatibility and security problem; firewalls and proxy servers will normally block this kind of traffic. SOAP was created to accomplish this task.

SOAP provides a way to communicate between applications running on different operating systems, with different technologies and programming languages.

It is a key element of Microsoft's. NET architecture for future Internet application development. UDDI is a platform-independent framework for describing services, discovering businesses, and integrating business services by using the Internet. UDDI are:. U niversal D escription, D iscovery and I ntegration.

A directory for storing information about web services. A directory of web service interfaces described by WSDL. UDDI Benefits. Any industry or businesses of all sizes can benefit from UDDI.

Before UDDI, there was no Internet standard for businesses to reach their customers and partners with information about their products and services. Nor was there a method of how to integrate into each other's systems and processes.

Problems the UDDI specification can help to solve:. Making it possible to discover the right business from the millions currently online. Defining how to enable commerce once the preferred business is discovered. Reaching new customers and increasing access to current customers. Solving customer-driven need to remove barriers to allow for rapid participation in the global Internet economy. Register now or log in to join your professional community.

HTML is a markup language that is used to build static non interactive and nonanimated webpages. Extensible Markup Language XML is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable.

It is defined in the XML1. CSS3 is divided into many different documents called Modules. Every module adds new capability or extends features defined in CSS2 over preserving backward compatibility. Because of the modularization in CSS3, every modules has different stability and is in different status. CSS3 has other added features such as new combinator, new CSS selectors, new pseudo-elements and new style properties[6].

The markup tells the Web browser how to display a Web page's words and images for the user. Each individual markup code is referred to as an element but many people also refer to it as a tag.

Some elements come in pairs that indicate when some display effect is to begin and when it is to end. By migrating to XHTML today, web developers can enter the XML world with all of its attendant benefits, while still remaining confident in their content's backward and future compatibility.

As such, they are readily viewed, edited, and validated with standard XML tools. XHTML documents can be written to operate better than they did before in existing browsers as well as in new browsers. The first draft was made public in, but not much happened until It is a markup language designed especially for Web documents. It defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. It allows designers to create their own customized tags.

It also enables the definition, transmission, validation, and interpretation of data between applications and organizations. XML is a text-based data format with strong support via Unicode for languages. It emphasizes simplicity, generality, and usability over the Internet. It is also widely used for the representation of arbitrary data structures, especially in web services. Image Courtesy: teamtreehouse. Wikipedia list additional DHTML features, such as DHTML allows the developers to: Animate text and images in their document, independently moving each element from any starting point to any ending point, following a predetermined path or one chosen by the user.

Embed a ticker that automatically refreshes its content with the latest news, stock quotes, or other data. Use a form to capture user input, and then process, verify and respond to that data without having to send data back to the server. Include rollover buttons or drop-down menus.
