Here are some technologies you should try to avoid when using XML.
Internet Explorer - XML Data Islands
What is it? An XML data island is XML data embedded into an HTML page.
Why avoid it? XML Data Islands only works with Internet Explorer browsers.
XML Data Island Example
This example uses the XML document "cd_catalog.xml".
Bind the XML document to an <xml> tag in the HTML document. The id attribute defines an id for the data island, and the src attribute points to the XML file:
The datasrc attribute of the <table> tag binds the HTML table to the XML data island.
The <span> tags allow the datafld attribute to refer to the XML element to be displayed. In this case, "ARTIST" and "TITLE". As the XML is read, additional rows are created for each <CD> element.
Internet Explorer - Behaviors
What is it? Internet Explorer 5 introduced behaviors. Behaviors are a way to add behaviors to XML (or HTML) elements with the use of CSS styles.
Why avoid it? The behavior attribute is only supported by Internet Explorer.
