Try:
trace("t3=" + opt.toXmlString());
(I think it's tracing the actual value of each node, which is "")
The toXmlString() value is a much bigger help when you're testing/debugging e4x
code.

Subject: [flexcoders] Having trouble with e4x and "for each" -- getting empty
XML value inside loop
Inside the "for each" loop I am getting a value that is empty. Here is
a sample program that illustrates the problem:
private function xmlTesting() : void
{
var myXml:XML = new XML("<root><commands> \
<command name='c1' > \
<options> \
<option name='o1'/> \
<option name='o2'/> \
</options> \
</command> \
<command name='c2' > \
<options> \
<option name='o3'/> \
<option name='o4'/> \
<option name='o5' /> \
</options> \
</command> \
</commands> \
</root>");
var myXml2:XMLList = myXml.commands.command.(@name=="c2");
trace("t1=" + myXml2[0].options);
trace ("t2=" + myXml2[0].options.option);
for each (var opt:XML in myXml2[0].options.option)
{
trace("t3=" + opt);
}
}
Here is the output I see in the trace window:
t1=<options>
<option name="o3"/>
<option name="o4"/>
<option name="o5"/>
</options>
t2=<option name="o3"/>
<option name="o4"/>
<option name="o5"/>
t3=
t3=
t3=
I don't understand why my value of "opt" in the "for each" loop shows
up as empty in the trace (t3). I must be missing something. Any help
appreciated. Thanks.
