Flex - Issues retrieving an XMLList

Question

Hello!

I'm having a problem retrieving a XMLList and I don't understand why.

I have an application that is running properly. It uses some data from two xml files called division.xml and store.xml. I noticed that I have some data in division.xml that should be in store.xml, so I did a copy/paste of the data from one file to the other. This is the data I copied:

<stores name="Japan" division="C300">   
    <store>
        <odeis>101</odeis>
        <name></name>
        <password></password>
        <currency></currency>
        <currSymbol></currSymbol>
    </store>    
    <store>
        <odeis>102</odeis>
        <name></name>
        <password></password>
        <currency></currency>
        <currSymbol></currSymbol>
    </store>
</stores>

In the application, I list all odeis codes and I need to retrieve the block store corresponding to the selected odeis code.

Before moving the data into store.xml, this is how I retrieved the block:

var node:XMLList = divisionData.division.(@name==HomePageData.instance.divisionName).stores.store.(odeis == HomePageData.instance.storeCodeOdeis)

This is how I retrieve it after copying the data into store.xml:

var node:XMLList = storeData.stores.(@name==HomePageData.instance.divisionName).store.(odeis == HomePageData.instance.storeCodeOdeis)

And I'm currently getting the following error:

ReferenceError: Error #1065: The variable odeis is not defined.

Could anyone enlighten me? Cause I really have no clue of why it is not working...

Thanks for any tips you can give.

Regards, BS_C3

Answer 1

In this line of code :

var node:XMLList = storeData.stores.(@name==HomePageData.instance.divisionName).store.(odeis == HomePageData.instance.storeCodeOdeis)

you are looking for the name attribute of the stores node. Which doesn't appear in your XML example. You are likely filtering all of your results before you even move into the store child node.

If this is not your problem, please post a more robust example of your storeData xml variable.

I copy/pasted and made almost no changes to your E4X query and had no issue. This runs just fine:

As far as I can tell you don't have any problem that should result in that error. Are you sure that the error is coming from there and not some other line of code?
