Accessing XML Parameters from Scripts

[Varsuuk]

This section always confused me - I sometimes get "dense" with things and have to revaluate it later. I did so, several times for a minute or 3 over a long time, everytime I came across this. I so very rarely used the indexing and when I did, I simply bruteforced it if I got it wrong until it was right. But I wanted to always "grok" it.

I recenty USED the [1]/[2] on my own in a script correctly and remembered to check again. This time, I still didn't get why "empy" & "normal" were treated so differently than "first" & "last". So, fed up with my denseness - I did what I always do, setup a test app. In this case the code I was working on, I added a simple control to and looked at the output:



<genericcontrol>
<states>
<empty>
<icon>emptyicon</icon>
</empty>
<normal>
<icon>normalicon</icon>
</normal>
</states>
<flags>
<first />
<second />
</flags>
<label>Control label</label>
<script>
function onInit()
Debug.console(states)
Debug.console(flags)
Debug.console(label)
end
</script>
</genericcontrol>


And the result:
57701

So, it seems my confusion was because for all these years that wiki page was in error? There IS no [2] to be seen, I couldn't figure out what there would be...

I've fixed the example on that page to match the example tags.

The additional indexes will only appear if multiple tags with the same name are defined.

For example:


<buttoncontrol>
<state><icon>buttonicon</icon</state>
<state><icon>buttonicon_down</frame></state>
<script>
function onInit()
Debug.console(state)
end
</script>
</buttoncontrol>

would return:


state = {
[1] = {
icon = {
[1] = "buttonicon",
},
},
[2] = {
icon = {
[1] = "buttonicon_down",
},
},
}

Cool that is exactly how I thought I understood it, the point of the array, but the example always vexxed me. Glad I finally gave up reading it and tried it.
Basically, I hadn't USED repeating groups until I worked on a template recently and that's when I remembered to go back and look at it again.
