What is CSS? CSS stands for Cascading Style Sheets. Styles define how to display HTML elements. 2. List the features of CSS?  Text handling including fonts, sizing, styles and spacing.  Printing specific features, downloadable fonts  Support for vertical running text, multicolumn layout facilities. 3. What are the three main parts of CSS syntax? The CSS syntax is made up of three parts: a selector, a property and a value. Selector {property: value} 1. The selector is normally the HTML element/tag we wish to define. 2. The property is the attribute we wish to change and each property can take a value. 3. The property and value are sepaerated by a colon and surrounded by curly braces. 4. How to insert a style sheet? When a browser reads a style sheet, it will format the document according to it. There are three ways of inserting a style sheet:  External Style Sheet  Internal Style Sheet  Inline styles  Multiple style sheets

The hardware and software that sits between the Internet and the local network, checking all the data that comes and goes out is called “firewalls”. The security is provided using SSL(Secure Socket Layer) in internet. 2. What is the use of http protocol? HTTP is a standard protocol that defines how a web client talks to a server and how data is transferred from the server back to the client. HTTP relies heavily on two other standards. MIME (Multipurpose Internet Mail Extensions), HTML 3. Define port.

It includes the definition of the properties of document object, many of which are themselves objects with their own properties. 2. What is Node object? Every element in a document tree refers to a Node object. Some nodes of the tree are JavaScript objects corresponding to HTML elements such html or body 3. Define Thread. A thread is the Java VM’s abstract representation of the processing to be performed to accomplish a particular task, possibly concurrently with other tasks 4. List out the methods of Cookie class.

b) Procedure: Step no.

Details of the step

1

Start the program

2

Keep the xml and java file in the same folder.

3

Import the required packages initially.

4

Use Buffer Reader to read the contents from the command prompt.

5

Get the name of the xml file from the user to execute.

6

Using XML Reader Factory obtain the parser.

7

If the document is correctly parsed then print document is well formed else print document is not well formed.

8

Stop the program.

c)Program: import java.io.*; import org.xml.sax.*; import org.xml.sax.helpers.*; public class Parsing_SAXDemo{ public static void main(String[] args) throws IOException { try { System.out.print("Enter the name of XML document "); BufferedReader input = new BufferedReader(new InputStreamReader(System.in));

String file_name = input.readLine(); File fp = new File(file_name); 38 Ms.B.NIRMALA AP/CSE

IP LAB MANUAL if (fp.exists()) { try { XMLReader reader = XMLReaderFactory.createXMLReader();

reader.parse(file_name); System.out.println(file_name + " is well-formed."); } catch (Exception e) { System.out.println(file_name + " is not well-formed."); System.exit(1);}} else { System.out.println("File is not present: " + file_name);} catch (IOException ex){ex.printStackTrace();}}}

e)Result: Thus to write a program using SAX along with XML file was successfully executed and verified. VIVA – QUESTIONS AND ANSWERS: 1. What is XML Namespace? An XML namespace is a collection of element and attribute names. Each namespace has a unique name that provides a means for document authors to unambiguously refer to elements with the same name in order to prevent collisions 2. What are XML Schemas? XML Schemas are part of the XML vocabulary and its addresses the standard for XML document validation by including a definition of a collection of standard data types which are used to describe data structures 3. What are the components of XSL?  XSLT-XSL Transformations which defines the semantics of the various elements and attributes of the XSL namespace.  XPATH – XML Path Language which defines the syntax and semantics of many of the attribute values used in XSL elements for accessing positions of the input XML  XSL-FO – XSL Formatting Objects is a separate vocabulary for defining style properties of an XML document.
