The XML Recommendation states that an XML document has both logical and physical structure. Physically, it is comprised of storage units called entities, each of which may refer to other entities, similar to the way that include works in the C language. Logically, an XML document consists of declarations, elements, comments, character references, and processing
XML Syntax and Parsing Concepts | Elements, Tags, Attributes, and Content | InformIT
Extensible HyperText Markup Language XHTML is part of the family of XML markup languages, how to write an good application xml document. It mirrors or extends versions of the widely used HyperText Markup Language HTMLthe language in which Web pages are formulated. While HTML, prior to HTML5 how to write an good application xml document, was defined as an application of Standard Generalized Markup Language SGMLa flexible markup language framework, XHTML is an application of XMLa more restrictive subset of SGML.
XHTML documents are well-formed and may therefore be parsed using standard XML parsers, unlike HTML, which requires a lenient HTML-specific parser. XHTML 1. The standard known as XHTML5 is being developed as an XML adaptation of the HTML5 specification. In the current XHTML 1. By migrating to XHTML today, content developers can enter the XML world with all of its attendant benefits, while still remaining confident in their content's backward and future compatibility. However, inthe Web Hypertext Application Technology Working Group WHATWG formed, independently of the W3C, to work on advancing ordinary HTML not based on XHTML.
The WHATWG eventually began working on a standard that supported both XML and non-XML serializationshow to write an good application xml document, HTML5in parallel to W3C standards such as XHTML 2. Inthe W3C's HTML working group voted to officially recognize HTML5 and work on it as the next-generation HTML standard. XHTML was developed to make HTML more extensible and increase interoperability with other data formats.
There are various differences between XHTML and HTML. The Document Object Model DOM is a tree structure that represents the page internally in applications, and XHTML and HTML are two different ways of representing that in markup.
Both are less expressive than the DOM — for example, "--" may be placed in comments in the DOM, but cannot be represented in a comment in either XHTML or HTML — and generally XHTML's XML syntax is more expressive than HTML for example, arbitrary namespaces are not allowed in HTML.
XHTML uses an XML syntax, while HTML uses a pseudo- SGML syntax officially SGML for HTML 4 and under, but never in practice, and standardised away from SGML in HTML5, how to write an good application xml document. Because the expressible contents of the DOM in syntax are slightly different, there are some changes in actual behavior between the two models. Syntax differences, however, can be overcome by implementing alternate translational framework within the markup.
First, there are some differences in syntax: [16]. In addition to the syntactical differences, there are some behavioral differences, mostly arising how to write an good application xml document the underlying differences in serialization. For example:. The similarities between HTML 4. To aid authors in the transition, the W3C provided guidance on how to publish XHTML 1. When measuring the adoption of XHTML to that of regular HTML, therefore, it is important to distinguish whether it is media type usage or actual document contents that is being compared, how to write an good application xml document.
Most web browsers have mature support [24] for all of the possible XHTML media types. Both Internet Explorer 7 released in and Internet Explorer 8 released in March exhibit this behavior. As long as support is not widespread, most web developers avoid using XHTML that is not How to write an good application xml document, [29] so advantages of XML such as namespaces, faster parsing and smaller-footprint browsers do not benefit the user.
In the early s, some Web developers began to question why Web authors ever made the leap into authoring in XHTML. XHTML regarding searching, indexing and parsing as well as future-proofing the Web itself. In OctoberHTML inventor and W3C chair Tim Berners-Leeintroducing a major W3C effort to develop a new HTML specification, posted in his blog that, "The attempt to get the world to switch to XML all at once didn't work. The large HTML-generating public did not move Some large communities did shift and are enjoying the fruits of well-formed systems The plan is to charter a completely new HTML group.
while at the same time updating the HTML specifications to address issues raised in the past few years. Simon Pieters researched the XML-compliance of mobile browsers [40] and concluded "the claim that XHTML would be needed for mobile devices is simply a myth".
December saw the publication of a W3C Working Draft entitled Reformulating HTML in XML. This introduced Voyager, the codename for a new markup language based on HTML 4, but adhering to the stricter syntax rules of XML.
By February the name of the specification had changed to XHTML 1. The second edition of XHTML 1. Modularization provides an abstract collection of components through which XHTML can be subsetted and extended. The feature is intended to help XHTML extend its reach onto emerging platforms, such as mobile devices and Web-enabled televisions. The initial draft of Modularization of XHTML became available in Apriland reached Recommendation status in April In October Modularization of XHTML was superseded by XHTML Modularization 1.
It was itself superseded by a second edition in July The W3C released a first draft in September ; Recommendation status was reached in May Other changes include removal of the name attribute from the a and map elements, and in the first edition of the language removal of the lang attribute in favour of xml:lang.
Although XHTML 1. In January a second edition of the document XHTML Media Types — Second Edition was issued, relaxing this restriction and allowing XHTML 1. A second edition of XHTML 1. Since information appliances may lack the system resources to implement all XHTML abstract modules, the W3C defined a feature-limited XHTML specification called XHTML Basic.
It provides a minimal feature subset sufficient for the most common content-authoring. The specification became a W3C recommendation in December Of all the versions of XHTML, XHTML Basic 1.
With XHTML 1. In addition to the Core Modules Structure, Text, Hypertext, and Listit implements the following abstract modules: Base, Basic Forms, Basic Tables, Image, Link, Metainformation, Object, Style Sheet, and Target. XHTML Basic 1. It also supports additional tags and attributes from other modules.
This version became a W3C recommendation on 29 July The current version of XHTML Basic is 1. This version also supports the lang attribute. XHTML-Print, which became how to write an good application xml document W3C Recommendation in Septemberis a specialized version of XHTML Basic designed for documents printed from information appliances to low-end printers.
XHTML Mobile Profile abbreviated XHTML MP or XHTML-MP is a third-party variant of the W3C's XHTML Basic specification. Like XHTML Basic, XHTML was developed for information appliances with limited system resources. In Octobera how to write an good application xml document company called the Wireless Application Protocol Forum began adapting XHTML Basic for WAP 2. WAP Forum based their DTD on the W3C's Modularization of XHTML, incorporating the same modules the W3C used in XHTML Basic 1.
Starting with this foundation, the WAP Forum replaced the Basic Forms Module with a partial implementation of the Forms Module, added partial support for the Legacy and Presentation modules, and added full support for the Style Attribute Module. Inthe WAP Forum was subsumed into the Open Mobile Alliance OMAwhich continued to develop XHTML Mobile Profile as a component of their OMA Browsing Specification.
To this version, finalized inthe OMA added partial support for the Scripting Module, and partial support for Intrinsic Events. XHTML MP 1. This version, finalized 27 Februaryexpands the capabilities of XHTML MP 1. Events in this version of the specification are updated to DOM Level 3 specifications i.
The XHTML 2 Working Group considered the creation of a new language based on XHTML 1, how to write an good application xml document.
The inputmode attribute from XHTML Basic 1. The XHTML2 WG had not been chartered to carry out the development of XHTML1. Since the W3C announced that it does not intend to recharter the XHTML2 WG, [6] and closed the WG in Decemberthis means that XHTML 1. Between August and Julythe W3C released eight Working Drafts of XHTML 2. This lack of compatibility with XHTML 1. x and HTML 4 caused some early controversy in the web developer community. x to XHTML 2. A ninth draft of XHTML 2.
HTML5 grew independently of the W3C, through a how to write an good application xml document group of browser manufacturers and other interested parties calling themselves the WHATWGor Web Hypertext Application Technology Working Group. The key motive of the group was to create a platform for dynamic web applications; they considered XHTML 2. x than XHTML 2. It adds many new elements not found in XHTML 1. x, however, such as section and aside tags.
The XHTML5 language, like HTML5, how to write an good application xml document, uses a DOCTYPE declaration without a DTD. Furthermore, the specification deprecates earlier XHTML DTDs by asking the browsers to replace them with one containing only entity definitions for named characters during parsing. This host language is one of the techniques used to develop Semantic Web content by embedding rich semantic markup.
An XHTML document that conforms to an XHTML specification is said to be valid. Validity assures consistency in document code, which in turn eases processing, but does not necessarily ensure consistent rendering by browsers. A document can be checked for validity with the W3C Markup Validation Service for XHTML5, the Validator. nu Living Validator should be used instead.
In practice, many web development programs provide code validation based on the W3C standards. The root element of an XHTML document must be htmland must contain an xmlns attribute to associate it with the XHTML namespace. The example tag below additionally features an xml:lang attribute to identify the document with a natural language :. In order to validate an XHTML document, a Document Type Declarationor DOCTYPEmay be used. A DOCTYPE declares to the browser the Document Type Definition DTD to which the document conforms.
A Document Type Declaration should be placed before the root element.
