Html2Xml Web Service


As you probably know, HTML is a "markup language" that uses "tags" (such as and <br> and <p>) to mark up text for formatting. The Extensible Markup Language (XML) is the universal format for structured documents and data on the Web.

Both HTML and XML use <, >, and & to create element and attribute structures. While HTML browsers accept or ignore mangled markup language, XML parsers and applications built on those parsers are less forgiving

The Html2Xml webservice takes an Html text and converts it into an Xml text. Some corrections are done to the Html to make it well-formed Xml.

You can use this webservice to screen scrape a web page and convert it to Xml. The Xml can then be used for further processing.

The Html2Xml is also registered in the UDDI registry.

ASP.NET RollOver Images


A RollOver image is an image that changes its picture when the mouse moves over it.

Example:      Move your mouse over the image!

There are many ways to implement this. One easy way of doing this is creating a helper class called 'RollOverImageManager'. This helper class does two things: add the 'onMouseOver' and 'onMouseOut' attributes to the image; add a javascript which preloads the 'MouseOver' images.


ASP.NET NumberBox Control


The NumberBox control is an ASP.NET control, which lets the user only input numerical values. The base class of NumberBox class is the TextBox class. It uses JavaScript to validate the KeyPress event. An extra RegularExpresionValidator can be used to validate the control.

Special public properties:

  • AllowNegatives
  • DecimalPlaces
  • DecimalSymbol
  • Text
  • Value
  • ValidationRegularExpression
