Insert a HTTPService component 113

3. In the <mx:Panel> tag, replace the value of the title property (“Blog Reader”) with the

following binding expression (in bold):

title="{feedRequest.lastResult.rss.channel.title}"

This expression binds the title field to the Panel control. The expression reflects the

structure of the XML. When XML is returned to a HTTPService component, the

component parses it into an ActionScript object named lastResult. The structure of the

lastResult object mirrors the structure of the XML document. To check the XML

structure, download the RSS feed’s XML file (at http://www.adobe.com/go/flex_blogfeed)

and open it in Internet Explorer.

The general structure of the XML is as follows:

<rss>

<title>

other child nodes of <channel>

<item>

<title>

other child nodes of <item>

</item>
