[flexcoders] Re: How to parse web services response doc containing namespace

2006-07-15 Thread kevntrace 
Thanks Derek.  I did read in the docs about declaring a namespace 
variable - indeed if you look at the code I posted, you will see I 
did exactly that with a variable named csw.  I also tried 
referencing the namespace in different ways - using the variable, 
using wildcards etc.  I still got nothing to work.

Could you take another look at my code and try to put in context how 
I would declare and use that namespace variable?  Like I said, I am 
a complete newbie to Flex, and this really is my first ever project 
and I've had no training.  So I'm not sure the namespace variable 
I've used is in scope when I'm trying to parse the result document, 
I'm not sure on how to mix MXML and ActionScript (so just giving me 
an extract of ActionScript code without showing me how to include it 
in my MXML doesn't really help too much).  I do appreciate all the 
responses from everyone though.


Excerpt where I declare the namespace var;
mx:Script
![CDATA[
import mx.controls.Alert;
private namespace csw 
= http://kevin.company.com/services/webservices/adobe/blogSvc/blogPo
rt;
use namespace csw;
]]
/mx:Script

Excerpt where I try to parse out using the namespace (none of these 
work);
mx:columns
mx:DataGridColumn headerText=Top Posts 
dataField=*::getMostPopularPostsResponse.*::ColumnList.*::row.*::ite
m/
mx:DataGridColumn headerText=Clicks 
dataField=getMostPopularPostsResponse.ColumnList.row.item 
width=75/
mx:DataGridColumn headerText=Blah 
dataField=csw::getMostPopularPostsResponse.csw::ColumnList.csw::row.
csw::item width=75/
/mx:columns

 I have been successful in doing that by declaring the namespace as 
a 
 local variable in ActionScript, then using it in the e4x query. 
For 
 instance:
 
 private var aps:Namespace = new Namespace
 (http://cadtel.com/APWebService;);
 
 model.currentOrderPaths = 
 results.aps::Order.aps::RelatedPaths.aps::Paths.aps::NetworkPath;
 
 Hope that helps,

[flexcoders] How to parse web services response doc containing namespace

2006-07-13 Thread kevntrace 
I am a complete newbie to Flex, ActionScript et al, so please 
forgive me if my questions appear simplistic.

I've implemented, and got working, the sample app which invokes a 
web service and displays the Top 5 popular posts from a blog service.

I now want to modify this app so it calls my own homegrown web 
service. I have been able to get the invocation working, and I get a 
valid response, which I confirmed by displaying the lastResult 
object in a textbox.

My problem now is I want to parse through the result document, which 
contains a namespace, and populate items on the form - I have not 
yet been successful in my attempts.

Here is the source code to my MXML application, followed by the WS 
response document;

MXML App


?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;

  /ns1:ColumnList
/ns1:getMostPopularPostsResponse


I tried creating an XMLListCollection object, but I got a compile 
error that, being a newbie, did not make sense. Here is the syntax I 
used.

mx:XMLListCollection id=xc
source={wsBlogAggr.getMostPopularPosts.lastResult}/

Can anyone help with info on how to parse the response doc?
