RE: [flexcoders] pulling my hair out with e4x!!!

When displaying XML, always use toXMLString().  The behavior you are
seeing with toString() which is what trace uses, is actually comformant
with ECMA.

 

trace(myXML.toXMLString());

yes, i tried it and have it working now- mostly user error but I must
say not being able to debug e4x expressions has ruined my day on many
occasions.

i was using toString on the xml list, thinking it would show me the xml
node it found and children (if any), toString was returning nothing and
a length of 0 so I assumed nothing was coming back.  when i added
children, the toString started showing me the node i was trying to find.

so, the blank response held the object i was looking for- but toString
was not showing it.

thanks for your help on this!

I've never used the attribute syntax you're using, so I'm not familiar
with it, but in your first employee example this syntax returned the
matching node, have you tried it?

debugModel.employees.node.(@display == "Employee First Name")

looks like you added another level in your latest example so for that
case this should return the node:

debugModel.group.(@label == "Employees").node.(@label == "Employee First
Name")

thanks guys, i'm sure that my xml is valid, i've refined what i'm trying
to do here a bit

public var debugModel:XML = 
        <mergefields label="Merge Fields">
            <group label="Employees">
                <node label="Employee First Name"
data="Employee_234234-234234-234234-234234" />
                <node label="Employee Last Name"
data="Employee_11111-111111-111111-111111" />
                <node label="Last Performance Note Date"
data="Employee_234234-234234-234234-234234" />
                <node label="Login"
data="Employee_234234-234234-234234-234234" />
                <node label="Login Link"
data="Employee_234234-234234-234234-234234" />
            </group>
...

what i'm trying to do is find any node that has a certain label, like so

var fieldNode:XMLList = debugModel.children().node.(attribute("label")
== "Employee First Name");

and no matter what i try it is not working, what it seems to be doing is
returning me all children of the node i'm looking for (there are none).
if I give that node some arbitrary child nodes, then the node is
returned with it's children, what gives?.

var fieldNode:XMLList = debugModel.employees.node.(attribute("display")

but this does...

public var thePeople:XML = <people>
                <person name="Mims Wright" suffix="III">
                    <age>27</age>

                </person>
.....

var fieldNode:XMLList = thePeople.person.(attribute("suffix") == "III");

i've tried a million different variations and i cannot get it to work
with my XML- what am i doing wrong here?

thanks,
