Benefits of XML
The very nature of XML is that it is a
structured document format that represents not only the information to be
exchanged but also the metadata encapsulating its meaning.
A) XML
Separates Data from HTML
If you need to display dynamic data in your
HTML document, it will take a lot of work to edit the HTML each time the data
changes. With XML, data can be stored in separate XML files. This way you can
concentrate on using HTML for layout and display, and be sure that changes in
the underlying data will not require any changes to the HTML.
With a few lines of JavaScript code, you can
read an external XML file and update the data content of your web page.
B) XML Simplifies
Data Sharing
In the real world, computer systems and
databases contain data in incompatible formats. XML data is stored in plain
text format. This provides a software- and hardware-independent way of storing
data. This makes it much easier to create data that can be shared by different
applications.
C) XML
Simplifies Data Transport
One of the most time-consuming challenges for
developers is to exchange data between incompatible systems over the Internet.
Exchanging data as XML greatly reduces this complexity, since the data can be
read by different incompatible applications.
D) XML
Simplifies Platform Changes
Upgrading to new systems (hardware or software
platforms), is always time consuming. Large amounts of data must be converted
and incompatible data is often lost. XML data is stored in text format. This
makes it easier to expand or upgrade to new operating systems, new
applications, or new browsers, without losing data.
E) XML
Makes Your Data More Available
Different applications can access your data,
not only in HTML pages, but also from XML data sources.With XML, your data can
be available to all kinds of "reading machines" (Handheld computers,
voice machines, news feeds, etc), and make it more available for blind people,
or people with other disabilities.
F) XML
is Used to Create New Internet Languages
A lot of new Internet languages are created
with XML.
Here are some examples:
·
XHTML
·
WSDL for
describing available web services
·
WAP and
WML as markup languages for handheld devices
·
RSS languages
for news feeds
·
RDF and
OWL for describing resources and ontology
·
SMIL for
describing multimedia for the web
