HTML
Headers are a simple form of text
formatting that vary text size based on
the headers “ level ”. The six header
elements (H1 through H6) are often used
to delineate new sections and subsections
of a page.
Actual size of the text of each header
element is selected by the browser and
can infact vary significantly between
browsers

Links are inserted using the A(anchor)
element.
To specify the address to link to , insert the
HREF attribute into the anchor tag as
follows: <A HREF = “address”>

HTML Forms to collect the information on
site we use forms.
<FORM METHOD = “POST” ACTION =
“/cgi-bin/formmail”>
Form is the element, Method attribute
indicates the way the web server will
organize and send you the form output.
METHOD = “post” causes changes to
server data.METHOD = “get” should be
used when your form does not cause
any changes in server-side data.

The INPUT element always requires the
TYPE attribute.Two other attributes are
NAME which provides a unique
identification for the INPUT element, and
VALUE which indicates the value that the
INPUT element sends to the server upon
submission.

CSS
Cascading Style Sheets (CSS) allow
you to specify the style of your page
elements (spacing, margins, etc)
separately from the structure of your
document (section headers, body text ,
links etc.)This separation of structure
from content allows greater manageability
and makes changing the style of your
document easier.
Save the file with extension .css and to
see the display save it with .html
extension.
44

CSS
.css ext is used for embedding the css file
into html code. The file with the .css file
extension can be created and saved using
the Notepad. When saving, however,
make sure you are not saving the file as a
text with the .txt file extension but as a
file with the .css file extension. External
CSS files contain only the CSS code
and are saved with the CSS file
extension. The file with the .css file
extension is then referenced in your HTML
by using the <link> instead of the
<style>.
45

CSS
Internal CSS
Cascading Style Sheets come in three
flavors: internal, external, and inline. We
will cover internal and external, as they
are the only flavors a designer should
utilize. In this lesson, we cover the basics
of the easier type, internal. When using
internal CSS, you must add a new tag,
<style>, inside the <head> tag.
46

CSS
External CSS is a file that contains only
CSS code and is saved with a ".css" file
extension. This CSS file is then referenced
in your HTML using the <link> instead of
<style>.
Why Use External CSS?
1) It keeps your website design and
content separate.
2) It's much easier to reuse your CSS
code if you have it in a separate file.
Instead of typing the same CSS code on
47

CSS
every web page you have, simply have
many pages refer to a single CSS file with
the "link" tag.
3) You can make drastic changes to your
web pages with just a few changes in a
single CSS file.
CSS Inline
It is possible to place CSS right in the
thick of your HTML code, and this method
of CSS usage is referred to as inline css.
48

CSS
Inline CSS has the highest priority out of
the three ways you can use CSS:
external, internal, and inline. This means
that you can override styles that are
defined in external or internal by using
inline CSS. However, inline CSS detracts
from the true purpose of CSS, to separate
design from content, so please use it
sparingly.

Example on Inline CSS
<!DOCTYPE html PUBLIC "-//W3C//DTD
HTML 5.0 Transitional//EN">

<HTML>

<HEAD><TITLE>Inline
Styles</TITLE></HEAD>
<BODY>
<P>Here is some text</P>
50

CSS
<P >Here is some more text</P>
<!- - Style attribute allows you to declare
inline, it specifies a style for an element,
semicolon specifies two properties - ->
<P STYLE = "font-size: 20pt; color:
#0000FF">Even more text</P>
</BODY>
<HTML>
Save the file with .html extension and
it is declared using STYLE attribute
51

Example on Internal CSS
<HTML>

<HEAD>
<TITLE>More Styles</TITLE>
<!- - This begins the style sheet section - -
>
<STYLE TYPE = "text/css">
52

CSS
A.nodec {text-decoration:none}
<!- - Applies the text decoration property
to all A elements whose class attribute is
set to nodec.Default browser rendering of
an A element is to underline,but here it is
set to none.The text-decoration property
applies decorations to text within an
element.Other possible values are
overline(line above),line-through(strike)
and blink.The .nodec appended to A is an
extension of class styles - ->
53

CSS Contd.
A:hover {text-decoration: underline;
color: red;
background-color: #CCFFCC}

<!- - hover is a pseudo-class.Pseudo-
classes give the author access to content
not specifically declared in the
document.The hover pseudo-class is
dynamically activated when the user
moves the mouse cursor over an A
element.- ->
54

CSS
<!–- CSS is a powerful tool for universal formatting,
each rule body begins and ends with curly braces-->
LI EM {color:red;
font-weight:bold}
<!- - declare a style for all EM(stress emphasis)
elements that are children of LI elements,Mushrooms
will be red and bold, to apply style for both LI and EM
separate the elements with comma.- ->
UL {margin-left: 75px}
UL UL{text-decoration: underline;
margin-left:15px }

CSS
In Internal CSS STYLE tag is used in
HEAD tag.
58

CSS Contd.
Example on External CSS
Create a CSS file with the STYLE tag as
below and save it with .css extension.

EM{background-color:
#8000FF;color:white}
H1{font-family: Arial, sans-serif}
59

CSS
P{ font-size: 18pt}
.blue{ color: blue}
</STYLE>
Now create an HTML file with .html
extension having a Link tag for linking
.css file, the advantage is as such that we
can call the . css file as many times as we
want in html file just like macros.

XML
XML
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
86

XML
The Difference Between XML and HTML
 XML is not a replacement for HTML.
 XML and HTML were designed with
different goals:
 XML was designed to transport and store
data, with focus on what data is
 HTML was designed to display data, with
focus on how data looks
 HTML is about displaying information,
while XML is about carrying information.

XML and XSL
 XML also has it's own styles language -
XSL. XSL stands for Extensible Styles
Language and is a very powerful language
for applying styles to XML documents.
XSL has two parts - a formatting
language and a transformation
language.
 The formatting language allows you to
apply styles similar to what CSS does.
Browser support for the XSL formatting
language is limited at this stage.
96

XML
 The transformation language is known as
XSLT (XSL Transformations). XSLT allows
you to transform your XML document into
another form. For example, you could use
XSLT to dynamically output some (or all)
of the contents of your XML file into an
HTML document containing other content.
97

XML
XSL (Extensible Style Language)
XSL defines the layout of an XML
document much like CSS defines the
layout of an HTML document-although
XSL is much more powerful. An XSL style
sheets provides the rules for displaying or
organizing an XML documents data. The
XML document that uses only HTML
elements and attributes.This part of XSL
concerned with transformation is called
XSL Transformation(XSLT)

An XML Schema describes the structure of
an XML document.A schema is Microsofts
expansion of the DTD is written in a
format dis-similar to the format of
XML.The W3C is currently developing a
schema format called Document Content
Description.(DCD).

Why Use XML Schemas?
XML Schemas Support Data Types
 One of the greatest strength of XML Schemas is
the support for data types.
 With support for data types:
 It is easier to describe allowable document
content
 It is easier to validate the correctness of data
 It is easier to work with data from a database
 It is easier to define data facets (restrictions on
data)
 It is easier to define data patterns (data formats)
 It is easier to convert data between different
data types
126

XML
XML Schemas Secure Data
Communication
 When sending data from a sender to a
receiver, it is essential that both parts
have the same "expectations" about the
content.
 With XML Schemas, the sender can
describe the data in a way that the
receiver will understand.
127

XML
XML Schemas are Extensible
 XML Schemas are extensible, because
they are written in XML.
 With an extensible Schema definition you
can:
 Reuse your Schema in other Schemas
 Create your own data types derived from
the standard types
 Reference multiple schemas in the same
document
128

XML
XML Advanced
XML on the Server
 XML files are plain text files just like HTML
files.
 XML can easily be stored and generated
by a standard web server.
129

XML
XML files can be stored on an Internet
server exactly the same way as HTML
files.

Transforming XML with XSLT on the Server
<%
'Load XML
set xml = Server.CreateObject("Microsoft.XMLDOM")
xml.async = false
xml.load(Server.MapPath("simple.xml"))
'Load XSL
set xsl = Server.CreateObject("Microsoft.XMLDOM")
xsl.async = false
xsl.load(Server.MapPath("simple.xsl"))
'Transform file
Response.Write(xml.transformNode(xsl))
%>
135

XML
 Example explained
 The first block of code creates an instance of
the Microsoft XML parser (XMLDOM), and
loads the XML file into memory.
 The second block of code creates another
instance of the parser and loads the XSL file
into memory.
 The last line of code transforms the XML
document using the XSL document, and
sends the result as XHTML to your browser.
Nice!

XML
XML Related Technologies
 Below is a list of XML technologies.
 XHTML (Extensible HTML)
A stricter and cleaner XML based version
of HTML.
 XML DOM (XML Document Object Model)
A standard document model for accessing
and manipulating XML.
137

XML
 XSL (Extensible Style Sheet Language) XSL
consists of three parts:
 XSLT (XSL Transform) - transforms XML into
other formats, like HTML
 XSL-FO (XSL Formatting Objects)- for formatting
XML to screen, paper, etc
 XPath - a language for navigating XML
documents
 XQuery (XML Query Language)
An XML based language for querying XML data.
 DTD (Document Type Definition)
A standard for defining the legal elements in an
XML document.
 XSD (XML Schema)
An XML-based alternative to DTD.
138

XML
 XLink (XML Linking Language)
A language for creating hyperlinks in XML documents.
 XPointer (XML Pointer Language)
Allows the XLink hyperlinks to point to more specific parts
in the XML document.
 SOAP (Simple Object Access Protocol)
An XML-based protocol to let applications exchange
information over HTTP.
 WSDL (Web Services Description Language)
An XML-based language for describing web services.
 RDF (Resource Description Framework)
An XML-based language for describing web resources.
 RSS (Really Simple Syndication)
A format for syndicating news and the content of news-like
sites.
 SVG (Scalable Vector Graphics)
Defines graphics in XML format.
139

XML
XML in Real Life
 XMLNews is a specification for exchanging
news and other information.
 Using such a standard makes it easier for
both news producers and news consumers
to produce, receive, and archive any kind
of news information across different
hardware, software, and programming
languages.
 An example XMLNews document:

XML - E4X
E4X adds direct support for XML to JavaScript.
XML As a JavaScript Object
E4X is an official JavaScript standard that adds
direct support for XML.
With E4X, you can declare an XML object variable
the same way as you declare a Date or an Array
object variable:
var x = new XML()
var y = new Date()
var z = new Array()
148

XML
E4X is an ECMAScript (JavaScript)
Standard
ECMAScript (European Computer
Manufacturers Association Script)
ECMAScript is the official name for
JavaScript. ECMA-262 (JavaScript 1.3)
was standardized in December 1999.
E4X is an extension of JavaScript that adds
direct support for XML. ECMA-357 (E4X)
was standardized in June 2004.
149

XML
The ECMA organization (founded in 1961)
is dedicated to the standardization of
Information and Communication
150

XML
Technology (ICT) and Consumer
Electronics (CE). ECMA has developed
standards for:
JavaScript
C# Language
International Character Sets
Optical Disks
Magnetic Tapes
Data Compression
Data Communication
and much more...
151

XML
Browser Support
Firefox is currently the only browser with
relatively good support for E4X.
There are currently no support for E4X in
Opera, Chrome, or Safari.
So far there is no indication for of E4X
support in Internet Explorer.
 The Future of E4X
 E4X is not widely supported. Maybe it
offers too little practical functionality not
already covered by other solutions:
152

XML
 For full XML processing, you still need the
XML DOM and XPath
 For accessing XMLHttpRequests, JSON is
the preferred format.
 For easy document handling, JQuery
selectors are easier.
