JSON: The Fat-Free Alternative to XML Let's compare XML and JSON on the attributes that the XML community considers important. From http://www.simonstl.com/articles/whyxml.htm. XML is simpler than SGML, but JSON is much simpler than XML. JSON has a much smaller grammar and maps more directly onto the data structures used in modern programming languages. JSON is not extensible because it does not need to be.

Is JSON better than XML? Syntax: JSON syntax is quite light and definitely less verbose than XML, with all of its start and end tags. When it comes down to pure byte-size, JSON can represent the same data as XML using fewer characters. Weight: Since JSON syntax requires fewer characters, it is lighter on the wire than XML. The question is if this really matters. Any large data set is going to be large regardless of the data format you use.

JSON In computing, JavaScript Object Notation or JSON (/ˈdʒeɪsən/ JAY-sən),[1] is an open-standard file format that uses human-readable text to transmit data objects consisting of attribute–value pairs and array data types (or any other serializable value).

What is XML Format? XML or eXtensible Markup Language is a markup language similar to HTML but was created with a different purpose. The former was designed for data storage and transport, while the latter deals on data display. XML is a simple text format used widely in data exchange over the Web and using other applications.

Extensible Markup Language (XML) Introduction. Extensible Markup Language (XML) is a simple, very flexible text format derived from SGML (ISO 8879).

An Introduction to JavaScript Object Notation (JSON) in JavaScript and .NET JSON is a data exchange format that was created from a subset of the literal object notation in JavaScript. While the syntax accepted by JavaScript for literal values is very flexible, it is important to note that JSON has much stricter rules.

Introduction to XML XML is extensible. The tags used to markup HTML documents and the structure of HTML documents are predefined. The author of HTML documents can only use tags that are defined in the HTML standard. XML allows the author to define his own tags and his own document structure. XML is a complement to HTML.

- (only $39.90) XML is a file format used to define objects and object attributes. It is also oftentimes referred to as Extensible Markup Language. This format is very close HTML, and yet many computer users choose XML because it allows to view files in simple text format and to edit them in standard text editors.

XML File Format eXtensible markup language. XML is a file extension for an Extensible Markup Language (XML) file format used to create common information formats and share both the format and the data on the World Wide Web, intranets, and elsewhere using standard ASCII text.XML is similar to HTML.Both XML and HTML contain markup symbols to describe the contents of a page or file. HTML, however, describes the content of a Web page (mainly text and graphic images) only in terms of how it is to be displayed and interacted with.ML is considered extensible because, unlike HTML, the markup symbols are unlimited and self-defining. XML is a simpler and easier-to-use subset of the Standard Generalized Markup Language (SGML) standard for how to create a document structure.

- XML DTDs Vs XML Schema. XML is a very handy format for storing and communicating your data between disparate systems in a platform-independent fashion. XML is more than just a format for computers — a guiding principle in its creation was that it should be Human Readable and easy to create.

Introduction to XML XML is a complement to HTML. It is important to understand that XML is not a replacement for HTML. In the future development of the Web it is most likely that XML will be used to structure and describe the Web data, while HTML will be used to format and display the same data.

JSON: What It Is, How It Works, & How to Use It JSON is short for JavaScript Object Notation, and is a way to store information in an organized, easy-to-access manner. In a nutshell, it gives us a human-readable collection of data that we can access in a really logical manner.

Introducing JSON JSON is built on two structures: 1  A collection of name/value pairs. 2  In various languages, this is realized as an object, record, struct, dictionary, hash table, keyed list, or associative array. 3  An ordered list of values. 4  In most languages, this is realized as an array, vector, list, or sequence.

Difference between JSON and XML The major differences. Clearly XML is somehow easier to understand for a human. That’s why it’s commonly used for configuration files (although lambdas and fluent APIs are recently emerging as a way of configuration). JSON, on ther other hand, is harder to read, but only from a human perspective.

An Introduction to JavaScript Object Notation (JSON) in JavaScript and .NET The toJSONString() function emits the array formatted according to the JSON standard. Parsing JSON text is even simpler. Since JSON is merely a subset of JavaScript literals, it can be parsed into an in-memory representation using the eval(expr) function, treating the source JSON text as JavaScript source code.he charm of JSON is in its simplicity. A message formatted according to the JSON standard is composed of a single top-level object or array. The array elements and object values can be objects, arrays, strings, numbers, Boolean values (true and false), or null.

An Introduction to E4X Javascript. So it is actually ECMAScript for XML in short E4X. E4X makes scripting for XML with JavaScript very simple With the support of E4X, we can declare an XML object variable the same way as we declare object variables in Javascript. For example: var a = new Array() similarly, var b = new XML() Parsing an XML document:

XML It is a textual data format with strong support via Unicode for different human languages. Although the design of XML focuses on documents, the language is widely used for the representation of arbitrary data structures such as those used in web services.

What Is An XML File & What Are Its Uses? [In Case You Were Wondering] An XML document basically is a type of style sheet that defines how its subordinate documents are to be read by the ‘machine’. Of course there is a crucial difference to HTML and style sheets. You basically skip the HTML because you create your own DTD and the whole process is simplified.

- Conclusion: We Need XML. 1  Need a light-weight, user-friendly form of SGML. 2  Need everything we like SGML for: Arbitrary document types. 3  XML provides a powerful marketing vehicle for selling the benefits of SGML to a new audience.  Gets a whole new group of people thinking about how to take advantage of structured markup.

JSON Stands for JavaScript Object Notation and is pronounced like the name Jason.. JSON is a text-based data interchange format designed for transmitting structured data. It is most commonly used for transferring data between web applications and web servers.

- Working with JSON Data. HTTP-based Web services frequently use JavaScript Object Notation (JSON) messages to return data back to the client. JSON objects can easily be instantiated in JavaScript, without parsing logic, which makes it a convenient format for messages in Web applications.

- Reasons to choose XML over JSON. 1  Easy to take XML and apply XSLT to make XHTML. 2  XML is supported by many more desktop applications than JSON. 3  JSON can be put in the XML on the way back to the client – the benefit of both!  Simply, AJAX includes XML in it and not JSON.

XML In computing, 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 through use of tags that can be created and defined by users.

- JSON is Like XML Because. Both JSON and XML are self describing (human readable) Both JSON and XML are hierarchical (values within values) Both JSON and XML can be parsed and used by lots of programming languages. Both JSON and XML can be fetched with an XMLHttpRequest.

JSON with Java JSON with Java. This chapter covers how to encode and decode JSON objects using Java programming language. Let's start with preparing the environment to start our programming with Java for JSON. Environment. Before you start with encoding and decoding JSON using Java, you need to install any of the JSON modules available. For this tutorial we have downloaded and installed JSON.simple and have added the location of json-simple-1.1.1.jar file to the environment variable CLASSPATH.
