Attempting to learn XML all over again...

Okay, I’ve been at this for a good few hours now, but no matter how much I read the help, it doesn’t seem to want to work.

I have some xml that I’ve managed to read in and am able to properly trace:

<fruitBowl>
<fruit name=”apples” colour=”red” seeds=”yes” />
<fruit name=”pears” colour=”green” seeds=”yes” />
<fruit name=”grapes” colour=”purple” seeds=”sometimes” />
<fruit name=”blueberries” colour=”blue” seeds=”no” />
</fruitBowl>

Now, I want to be able to get the first fruit (and the next after, etc), and its attributes.
Logically, I think I should be able to do this by going (or something similar):

xmlListObject.child(0).attribute(“name”)

But actionscript 3 seems to disagree. When I trace the above (and tracing "xmlList.Object.child(0)" ), I get a blank (which appears to be because the tag actually has no value).

If I trace xmlListObject itself, I get my whole xml. If I trace xmlListObject.length(), it does return the right amount of children. But I can’t seem to isolate any 1 child and get an attribute from it.

Any ideas?

Hi kglad,

Hm, you know what? You’re right. Going back to my xml reading for the 3rd time I see what I had in my first post does actually work...

It was something else in my logic, it seemed I was accidentally trying to get the child of a child the first time, which didn’t exist (which was why it was blank every time). Reading my ‘answer’ again, it seemed I had unknowingly fixed that and thought it was the real ‘answer’. =b But now I see the root of the problem.

Thanks kglad for the insight.

Ah, I’ve finally gotten it:

<fruitBowl>
<fruit name=”apples” colour=”red” seeds=”yes” />
<fruit name=”pears” colour=”green” seeds=”yes” />
<fruit name=”grapes” colour=”purple” seeds=”sometimes” />
<fruit name=”blueberries” colour=”blue” seeds=”no” />
</fruitBowl>

From the xmlList that contains all of this, I first need to access its children (all the fruit nodes).

xmlObject.children() will give me:

<fruit name=”apples” colour=”red” seeds=”yes” />
<fruit name=”pears” colour=”green” seeds=”yes” />
<fruit name=”grapes” colour=”purple” seeds=”sometimes” />
<fruit name=”blueberries” colour=”blue” seeds=”no” />

Then to get the first element I can go:

xmlObject.children()[0] (like in an array)

<fruit name=”apples” colour=”red” seeds=”yes” />

Finally to get an attribute ‘colour’:

xmlObject.children()[0].attribute(“colour”);

If there are better/other ways to do this, then feel free to comment.

you have a malformed xml file. there should be an equal sign after colour in blueberries.

Sorry, that was a typo. I’ve fixed it, but my xml does validate in the first place.
