hi ajay Extensible Markup Language (XML) is a general-purpose specification for creating custom markup languages.[1] It is classified as an extensible language because it allows its users to define their own elements. Its primary purpose is to facilitate the sharing of structured data across different information systems, particularly via the Internet,[2] and it is used both to encode documents and to serialize data. In the latter context, it is comparable with other text-based serialization languages such as JSON and YAML.[3]

It started as a simplified subset of the Standard Generalized Markup Language (SGML), and is designed to be relatively human-legible. By adding semantic constraints, application languages can be implemented in XML. These include XHTML,[4] RSS, MathML, GraphML, Scalable Vector Graphics, MusicXML, and thousands of others. Moreover, XML is sometimes used as the specification language for such application languages.

XML is recommended by the World Wide Web Consortium. It is a fee-free open standard. The W3C recommendation specifies both the lexical grammar and the requirements for parsing.

I think importing XML documents will become more and more important in the future. You can manage the XML document as a kind of database, while the HTML document contains all information about the displaying of the data.

Anyway, try it first by clicking the link and loading some crucial information about the Roman emperors of the Julian-Claudian dynasty. You can also view the XML document separately.

First I import the document emperors.xml, then I enter the XML document through the W3C DOM and extract the data I need, while building a table to display the data.
Native XML databases have grown in popularity along with XML, because data is stored as native XML, rather than through tables in a traditional database. Using a native XML database means that a change to the schema requires minimal changes to your code and no change to the database. PHP and Java developers can benefit greatly from using native XML databases.

XML (Extensible Markup Language) is a markup lanugage that enables you to store data in a structured format by using meaningful tags. The term "eXtensible: implies that you can extend your ability to describe a document by defining.

XML stands for "EXtensible Markup Language" that is a markup language much like HTML.XML was designed to carry data, not to display data.In XMLtags are not predefined, you must define your own tags.

There are two approaches to create XML pages.

First: The standalone can be created by simply making some alterations to your current HTML document:

Second: You would create a basic text file with a DTD extension. This file would hold all the entities.

XML import :
xml import is process to access xml data in a application program.

Uses of XML :

Relational database systems cannot meet all the demands of electronic business because they process data independently of its context. Traditional databases may be well suited for data that fits into rows and columns, but cannot adequately handle rich data such as audio, video, nested data structures or complex documents, which are characteristic of typical Web content. To deal with XML, traditional databases are typically retrofitted with external conversion layers that mimic XML storage by translating it between XML and some other data format.

XML databases, on the other hand, store XML data natively in its structured, hierarchical form. Queries can be resolved much faster because there is no need to map the XML data tree structure to tables. This preserves the hierarchy of the data and increases performance.

What is XML?

* XML stands for EXtensible Markup Language
* XML is a markup language much like HTML
* XML was designed to carry data, not to display data
* XML tags are not predefined. You must define your own tags
* XML is designed to be self-descriptive
* XML is a W3C Recommendation
There are several ways to import XML. None of them are truly cross browser, so a combination must be used. The two main techniques have a normal constructor for standards based browsers, and an ActiveX version for Internet Explorer. The syntax used to load the document is the same in both versions, and the functionality is comparable.
* XML DOM Creates an XML document object, then makes it load an XML file. It uses either the createDocument method of the document.implementation object (followed by a call to load()), or the Microsoft.XMLDOM ActiveX object.
* XMLHttpRequest creates an HTTP request using GET or POST and uses it to load an XML file. It uses the XMLHttpRequest contructor, or the Microsoft.XMLHTTP ActiveX object.
* The iframe technique loads an XML page in an iframe then parses it as a document.

These techniques are equivalent for most purposes, except that the second can pass POST information in the request, allowing for more than 4KB of encoded data to be sent to the server (either can pass GET information in the requested URL string). Since the iframe technique cannot use POST without creating history entries, I restrict myself to GET in all situations. The second technique does offer superior error handling (in case the XML file does not load), and can handle synchronous/asynchronous loading better.

As well as that, the second technique is being included in the upcoming W3C specification, and is the basis of most AJAX (the annoying buzzword, not the bathroom cleaner) applications. It offers an extra advantage that it can deal with plain text files, and raw source code instead of just providing a DOM interface.

PPK's example uses only the first technique.

Newer versions of ICEbrowser also support their own version of XMLHttpRequest created using window.createRequest() or new XMLHttpRequest() but they do not provide a responseXML DOM, and are useless here. It would be possible to cludge this script to force ICEbrowser to use the iframe like it used to, but the DOM of the iframe page also seems to be broken. So it is better to just wait until it supports XMLHttpRequest properly.

Note: If you want to submit form data to construct the XML data URL, I have demonstrated how in a previous email.

I could just use XMLHttpRequest and one of the ActiveX techniques, which would extend support to a few more browsers, as well as making the script a lot easier, since repeated 'if' tests are not required, and no browsers produce errors. However, I am not satisfied with just that. What I do is I start the same way as PPK, but using XMLHttpRequest instead of document.implementation. Failing that, I try new ActiveXObject('Microsoft.XMLHT TP') with a check to prevent problems with ICEbrowser then fall back to new ActiveXObject('Microsoft.XMLDO M') if XMLHTTP is not available (either ActiveX method could be used, but the latter is perhaps a little easier and will also work with file:// URLs, but has broken implementations on many installs). I also use try-catch to prevent IE 5 Mac from failing when it tries to use its crippled ActiveXObject. I did try the same for ICEbrowser, but apparently it fails to use try-catch properly for this sort of situation.

At this stage, I have done almost the same as PPK, apart from my error avoiding. However (and here is the critical part), what I do next is I check if both of those techniques failed and if they did, I create a hidden iframe, and load the XML document into it. Normally, I would use onload, but I found that only Opera 7.5+ uses it here, despite the fact that IE 5 Mac and ICEbrowser also use t

(EXtensible Markup Language) An open standard for describing data from the W3C. It is used for defining data elements on a Web page and business-to-business documents. XML uses a similar tag structure as HTML; however, whereas HTML defines how elements are displayed, XML defines what those elements contain. While HTML uses predefined tags, XML allows tags to be defined by the developer of the page. Thus, virtually any data items, such as "product," "sales rep" and "amount due," can be identified, allowing Web pages to function like database records. By providing a common method for identifying data, XML supports business-to-business transactions and has become "the" format for electronic data interchange and Web services.
An XML document is self defining if an XML schema is included in it. Schemas, such as W3C XML Schema, are written in XML and identify the tags and their relationships to each other in the document.
