[Xerte] childNodes count?

[Dave Burnett]

I agree, I'll change the structure.

I'm just curious now as to how to get the count in an associative array or object.
Most of the AS refs say you have to loop over it (for key in object) ++ type thing.
But I can't get it to work.
Some other day...

It’s the innards of XMLToObject() that creates the 4. I’d not do it your way because you can’t identify your navItems as navItems: they are all different types of node, when really they are different types of navItem.

Or I could add count="6" to the navigation tag:
<navigation count="6">

:-)


I do prefer property arrays to index arrays. Way more idiot-proof.
An index array will entail nested loops each time I want to get a value.

I just hate not seeing why this gives me 4:

debug(templateData.brand[0].navigation[0].copy[0].tooltip);//correct
debug(templateData.brand[0].navigation[0].dict[0].tooltip);//correct
debug(templateData.brand[0].navigation[0].open[0].tooltip);//correct
debug(templateData.brand[0].navigation[0].home[0].tooltip);//correct
debug(templateData.brand[0].navigation[0].next[0].tooltip);//correct
debug(templateData.brand[0].navigation[0].back[0].tooltip);//correct


debug(templateData.brand[0].navigation[0].length); //4

debug(templateData.brand[0].navigation[0].length);

4

I tried that and about 2 dozen other variations.
I variously get undefined, 4 or 9.From: Julian.Tenney at nottingham.ac.uk

Here's the structure being read into templateData:

<brand>
  <background graphic="intromen_ease.gif" x="0" y="0" w="100" h="200">
  </background>
  <navigation>
    <back swf="btnBack_ease.swf" tooltip="Previous page Shortcut-key: Alt+Left" x="100" y="200" w="100" h="200"></back>
    <next swf="btnNext_ease.swf" tooltip="Next page Shortcut-key: Alt+Right" x="200" y="200" w="100" h="200"></next>
    <home swf="btnHome_ease.swf" tooltip="Unit home page Shortcut-key: Alt+Home" x="300" y="200" w="100" h="200"></home>
    <open swf="btnOpen_ease.swf" tooltip="Open a unit Shortcut-key: Ctrl+O" x="400" y="200" w="100" h="200"></open>
    <dict swf="btnDict_ease.swf" tooltip="Show the Dictionary" x="500" y="200" w="100" h="200"></dict>
    <copy swf="btnCopy_ease.swf" tooltip="Copy text to your scrapbook" x="600" y="200" w="100" h="200"></copy>
  </navigation>
</brand>


inspect(templateData.brand[0].navigation[0])

gives me 6 children:

copy : null
dict : null
open : null
home : null
next : null
back : null


debug(templateData.brand[0].navigation[0].childNodes.length);

gives me 4


fah.
