If what you are doing is looking for nodes with firstnames then you can do
something like this:
Assuming Jason's XML with attributes:
var peopleList:XML = <people>
<person firstName="Bob" lastName="Smith">
<person firstName="Timmy" lastName="Smith" />
<person firstName="Jenny" lastName="Jones" />
<person middleName="Beth" lastName="Jones" />
</person>
<person firstName="Tom" lastName="Williams">
<person firstName="Sa" lastName="Williams" />
</person>
</people>;
var firstNames:XMLList = peopleList..*.(hasOwnProperty("@firstName"));
trace(firstNames);
The ..* automatically selects all nodes that have a firstName attribute
regardless of nesting. Thus you could loop over firstNames with no recursion
and get a list of all firstnames. The list will contain all the nodes witha
firstName attribue, so you will get one node with Bob as firstName that still
has 3 children, but you will also get 2 of those children in the firstNames
list so you would simply ignore the children inside of Bob. For testing
purposes I purposefully added an extra child node with no firstName to Bob.
This is the result
<person firstName="Bob" lastName="Smith">
<person firstName="Timmy" lastName="Smith"/>
<person firstName="Jenny" lastName="Jones"/>
<person middleName="Beth" lastName="Jones"/>
</person>
<person firstName="Timmy" lastName="Smith"/>
<person firstName="Jenny" lastName="Jones"/>
<person firstName="Tom" lastName="Williams">
<person firstName="Sa" lastName="Williams"/>
</person>
<person firstName="Sa" lastName="Williams"/>
You can do something similar with your structure:
var peopleList:XML = <allPeople>
<person>
<personFirstName>Bob</personFirstName>
<personLastName>Smith</personLastName>
<person>
<personFirstName>Timmy</personFirstName>
<personLastName>Smith</personLastName>
</person>
<person>
<personFirstName>Jenny</personFirstName>
<personLastName>Smith</personLastName>
</person>
</person>
<person>
<personFirstName>Tom</personFirstName>
<personLastName>Williams</personLastName>
<person>
<personFirstName>Sa</personFirstName>
<personLastName>Williams</personLastName>
</person>
</person>
</allPeople>;
var firstNames:XMLList = peopleList..*.personFirstName;
trace(firstNames);
result:
<personFirstName>
Bob
</personFirstName>
<personFirstName>
Timmy
</personFirstName>
<personFirstName>
Jenny
</personFirstName>
<personFirstName>
Tom
</personFirstName>
<personFirstName>
Sa
</personFirstName>
Your structure produces a simpler list, however I favor Jason's attribute
version as it is far more compact, simpler to read, etc.
Personal preference.
But if you don't need to do recursion then don't. Saves many headaches.

sorry a couple of typos... the function should be:
function createPeople (_xml:*):void
{
var xmlList:XMLList=_xml.children();
for each (var fn_xml in xmlList) {
createPeople(fn_xml);
trace(item_xml.personFirstName);
}
}

I would write the XML this way instead:
<people>
<person firstName'"Bob" lastName="Smith">
<person firstName="Timmy" lastName="Smith" />
<person firstName="Jenny" lastName="Jones" >
<person firstName="Sal" lastName="Stephens" />
</person>
</person>
<person firstName="Tom" lastName="Williams">
.etc.
Also, recursive functions call themselves - and then break when some
value or condition is reached.... for yours, add to your object, and
then check to see if there are child nodes in the xml below it, if so,
call the function again to add more, if not, break out of the function.
However, this will only get you through the top level nodes and one of
the top level nodes's sub nodes - not the others - I actually can't
think of how to get into the OTHER sub-nodes - though I know there are
people on this list who do. I know what some people do is make the first
pass on the first level, then the second pass on the second, and so on,
adding to the object as they go. Don't ask me to send you an example
though.
Recursive functions are also quite hard to wrap your head around. :)

So I have this xml:
<allPeople>
<person>
<personFirstName>Bob</personFirstName>
<personLastName>Smith</personLastName>
<person>
<personFirstName>Timmy</personFirstName>
<personLastName>Smith</personLastName>
</person>
<person>
<personFirstName>Jenny</personFirstName>
<personLastName>Smith</personLastName>
</person>
</person>
<person>
<personFirstName>Tom</personFirstName>
<personLastName>Williams</personLastName>
<person>
<personFirstName>Sa</personFirstName>
<personLastName>Williams</personLastName>
</person>
</person>
To start I am just trying to recursively go through this to grab the
first names. I am trying:
createPeople(peopleXML)
function createPeople (_xml:*):void
{
var xmlList:XMLList-_xml.children();
for each (var fn_xml in xmlList) {
createChart(fn_xml);
trace(item_xml);
}
}
I am wondering - am I on the right track? Does the xml look well-formed
for doing what I am trying to do?
Thanks!
