e4x is the acronym for ECMA Script 4 XML, or something like that. When
you specify it as the resultFormat for an RPC data service call, it
means that your result object will be an XML object and that you can use
the new, Actionscript 3 xml selection expressions with it. If you do
NOT specify it explicitly, the resultFormat is object, which means that
your result data is converted int a nested mx:Object structure. This is
significant to your question because it affects how you will examine the
result object. Also, the default object conversion seems to simplify
namespace issues, but I find it harder to work with than e4x xml.
First, set up a result handler function. You can do this on the service
level of for individual operations. I'll show one on the tag. In the
Tag, set the function name:
<mx:WebService id="get_home_list" result="onResult(event)" ...>
And the function declaration:
private function onResult(oEvent:ResultEvent):void
{
oEvent is an object containing your result data. What that object
contains first depends on the resultFormat you have specified for the
WebService or the operation, as discussed above.
If you are using the default, try:
trace(ObjectUtil.toString(oEvent.result))
if you are using e4x xml, then try:
trace( XML(oEvent.result).toXMLString() )

I'm not sure what e4x is. Here is my webservice declaration. It
returns a query from a ColdFusion web service (Flex=ArrayCollection, I
think).
<mx:WebService id="get_home_list"
wsdl="http://imd9.state.or.us/ex/bcd/loisflex/lois.cfc?WSDL
<http://imd9.state.or.us/ex/bcd/loisflex/lois.cfc?WSDL> "
useProxy="false" showBusyCursor="true" >
<mx:operation name="qry_get_home_list">
<mx:request>
<q_home_id>0</q_home_id>
</mx:request>
</mx:operation>
</mx:WebService>
Thanks.
