XML is a markup language that was first invented as a means of conveying and displaying data individually on any software. Its major aim was to let properly structured documents to be viewed on the internet consistently despite the browser in use.
XML is much powerful that HTML as it’s more flexible. HTML offers and actually predefines stringent tags for data. For instance, title should always remain within the title tag and body elements should remain within the body tag etc.
On the other hand, XML lets you create your own tags as it gives specifications the standards in which you can elaborate your tags. This means that you make use of any type of description you would like to name your tags or containers. You can as well define as many languages as you would like with reference to the standards that are specified by XML, and so we can conclude that XML is similar to a meta-mark-up language.
Pros of XML
• XML has awesome compression abilities that are much better than HTML. This gives XML an edge in streaming of data.
• XML provides much better facilities for browser performance and presentation
• Since XML has great hypertext linking abilities, information on XML is richer and vibrant.
• One is able use their one mark-up elements and you can as well mark up tags on the fly that were not in existence previously
Cons of XML
• XML is not totally developed to provide total freedom when doing any programming activities through full standards compliance. Although XSLT and XSL are in the right direction, they are far from getting into the right state.
• XML can sometimes be too large which is why in web services, JSON is the preferred choice
• XML has problems with Hypertext Transfer Protocol(XML-HTTP)
Generally, XML is a much more developed form of working with information. But if you will be creating XML based web applications, it’s vital that you understand the challenges that may affect any XML server performance. For instance, the type of data, the attributes to elements, the ratio of tags to text and the level of waste white space all have an impact on the performance of XML servers.
Another great thing with XML is the incorporation of DOM from Microsoft. DOM (Document Object Model) is an excellent tool that is used in loading and parsing XML files. DOM is an excellent way to collect information, move through your files and manipulate files.
It’s also a great way to work with your XML file in a specific way to create and display XML documents using codes such as visual basic and ASP. In addition, one can as well use XML VB tool like Liquid XML Visual Basic and MSMXL to assist in parsing, editing and creating your VB from your XML.
