Xml & scripting
Download as PPTX, PDF1 like123 views
XML is a markup language like HTML that was designed to store and transport data. Unlike HTML which has predefined tags, XML allows authors to define their own tags. XML focuses on describing what the data is, while HTML focuses on how data looks when displayed. A sample XML document is provided that defines a bookstore with multiple books, each with attributes like title, author, year, and price. Several popular scripting languages are also discussed like Bash, Node.js, Ruby, Python, and Perl. Scripting languages are interpreted rather than compiled and make it easier to integrate with other languages and add functionality to applications.
Xml & scripting
- 1. XML & Scripting BY:SURBHI SAROHA
- 2. XML XML stands for eXtensible Markup Language XML is a markup language much like HTML XML was designed to store and transport data XML was designed to be self-descriptive XML is a W3C Recommendation
- 3. The Difference Between XML and HTML XML and HTML were designed with different goals: XML was designed to carry data - with focus on what data is. HTML was designed to display data - with focus on how data looks. XML tags are not predefined like HTML tags are.
- 4. XML Does Not Use Predefined Tags The XML language has no predefined tags. The tags in the example above (like <to> and <from>) are not defined in any XML standard. These tags are "invented" by the author of the XML document. HTML works with predefined tags like <p>, <h1>, <table>, etc. With XML, the author must define both the tags and the document structure.

- 7. Scripting All scripting languages are programming languages. The scripting language is basically a language where instructions are written for a run time environment. They do not require the compilation step and are rather interpreted. It brings new functions to applications and glue complex system together. A scripting language is a programming language designed for integrating and communicating with other programming languages.
- 8. There are many scripting languages some of them are discussed below: bash: It is a scripting language to work in the Linux interface. It is a lot easier to use bash to create scripts than other programming languages. It describes the tools to use and code in the command line and create useful reusable scripts and conserve documentation for other people to work with. Node js: It is a framework to write network applications using JavaScript. Corporate users of Node.js include IBM, LinkedIn, Microsoft, Netflix, PayPal, Yahoo for real-time web applications. Ruby: There are a lot of reasons to learn Ruby programming language. Ruby’s flexibility has allowed developers to create innovative software. It is a scripting language which is great for web development.
- 9. CONT….. Python: It is easy, free and open source. It supports procedure-oriented programming and object-oriented programming. Python is an interpreted language with dynamic semantics and huge lines of code are scripted and is currently the most hyped language among developers. Perl: A scripting language with innovative features to make it different and popular. Found on all windows and Linux servers. It helps in text manipulation tasks. High traffic websites that use Perl extensively include priceline.com, IMDB.
- 10. Advantages of scripting languages: Easy learning: The user can learn to code in scripting languages quickly, not much knowledge of web technology is required. Fast editing: It is highly efficient with the limited number of data structures and variables to use. Interactivity: It helps in adding visualization interfaces and combinations in web pages. Modern web pages demand the use of scripting languages. To create enhanced web pages, fascinated visual description which includes background and foreground colors and so on. Functionality: There are different libraries which are part of different scripting languages. They help in creating new applications in web browsers and are different from normal programming languages.
