I'm sure this will have an obvious answer and that it's something that
I've just been looking at for too long...
I'm trying to select a node from xml where a child has a specific value
For example:
var xml:XML =
<communication xmlns="stuffHERE">
<folder>
<id>1</id>
<folder>
<id>2</id>
</folder>
<folder>
<id>3</id>
<folder>
<id>4</id>
</folder>
</folder>
</folder>
In the above, I'm using an e4x expression that looks like:
xml..folder.(id == 3)
All works well when I don't have a namespace declared.
When I have a name space declared, I keep getting nothing back.
I'm using the actionscript object: namespace test="http..."
use namespace test
Any ideas on what I'm doing wrong? BTW, I've tried many, many
different e4x expressions, none that work.
Also, any techniques for debugging e4x? I've already included some
dynamic e4x expression parsers that I found on the web. But I find
that while I can get the expression to work fine dynamically, it still
doesn't work.
I've posted this over in teh Adobe Forums, too, as I'm not really sure
which place is the best place to go for help.
Thanks a bunch
Here's my test MXML file, sorry for how ugly it looks in this window.,
I"m hoping you can just copy this and paste it into a new MXML file
for you to look at...:
