Now, AS2/1.5 alone does not support xpath, so you last line wont work like that. I have seen an AS library that provides Xpath, and have heard, via an accidental leak at MM that Flex 2.0 will have an xpath-like node location syntax.
With the current codebase, you can either let Flex convert your xml into an mx:Object, and then use dot notation to navigate within the data, or you can specify resultFormat="xml", and use the XML class members to manipulate the data.
See the XML Class in the livedocs for the available members. Sorry, "getElementsByTagName" is not one of them. You willeither need to know the index of the node in the childNodes array, or loop through them to manually match your attribute or nodeName.

Subject: [flexcoders] Data service results format: VO or XML?
Hello all,
I have read some posts on how to pass data from the service tier to the
Flex tier using VOs or arrays of VOs. I dont think it is a bad idea to
use these objects but:
Is it possible to return results in XML format and then bind parts of
this XML "document" to Flex UI components like a datagrid, list, etc?
This would be something like :
// not real code
1) myDg.dataProvider = event.result.getElementsByTagName("prices")
and then:
columnName="PRICE"
colomnName="another attr or subelement"
...
2) myList.dataProvider = event.result.getElementsByTagName("shops")
and even more advanced :
3) myDg.dataProvider = event.result/[EMAIL PROTECTED] < 200]
Thanks all
