<p class="intro">Here are some technologies you should try to avoid when
using XML.</p>
<hr />
<h2>Internet Explorer - XML Data Islands</h2>
<p><b>What is it? </b>An XML data island is XML data embedded into an HTML page.</p>
<p><b>Why avoid it?</b> XML Data Islands only works with Internet Explorer browsers.</p>
<p><b>What to use instead?</b> You should use JavaScript and XML DOM to parse
and display XML in HTML.</p>
<p>For more information about JavaScript and XML DOM, visit our <a href="../dom/default.asp">XML
DOM tutorial.</a></p>
<hr />
<h2>XML Data Island Example</h2>
<p>This example uses the XML document "<a target="_blank" href="cd_catalog.xml">cd_catalog.xml</a>".</p>
<p>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:</p>
<table width="100%" border="1" class="ex" cellspacing="0">
<tr>
<td>
<pre><html>
<body>
<xml id="cdcat" src="cd_catalog.xml"></xml>
<table border="1" datasrc="#cdcat">
<tr>
<td><span datafld="ARTIST"></span></td>
<td><span datafld="TITLE"></span></td>
</tr>
</table>
</body>
</html></pre>
</td>
</tr>
</table>
<p>The datasrc attribute of the <table> tag binds the HTML table to
the XML data island.</p>
<p>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.</p>
<p>If you are using Internet Explorer, you can
<a target="_blank" href="tryit.asp@filename=cd_catalog_island">try
it yourself</a>.</p>
<hr />
<h2>Internet Explorer - Behaviors</h2>
<p><b>What is it? </b>Internet Explorer 5 introduced behaviors. Behaviors are a
way to add behaviors to XML (or HTML) elements with the use of CSS styles.</p>
<p><b>Why avoid it?</b> The behavior attribute is only supported by Internet Explorer.</p>
<p><b>What to use instead? </b>Use JavaScript and XML DOM (or HTML DOM) instead.</p>
<hr />
<h2>Example 1 - Mouseover Highlight</h2>
<p>The following HTML file has a <style> element that defines a behavior for the <h1>
element:</p>
<table border="1" width="100%" class="ex" cellspacing="0" id="table7">
<tr><td width="100%">
<pre><html>
<head>
<style type="text/css">
h1 { behavior: url(behave.htc) }
</style>
</head>
<body>
<h1>Mouse over me!!!</h1>
</body>
