This function returns the number of children an element has.
Syntax
int getElementChildrenCount ( element parent )
Required Arguments
- parent: the parent element
Returns
Returns the number of child elements, or false if the parent element does not exist.
Example
To get the number of children the 'team1' element has:
<team1 id="red">
<spawnpoint id="spawnpoint_0" posX="2507.8715820313" posY="2772.6071777344" posZ="10.8203125" rot="270" skin="285"/>
<spawnpoint id="spawnpoint_1" posX="2508.060546875" posY="2780.3647460938" posZ="10.8203125" rot="270" skin="285"/>
<spawnpoint id="spawnpoint_2" posX="2508.0053710938" posY="2776.2897949219" posZ="10.8203125" rot="270" skin="285"/>
<spawnpoint id="spawnpoint_3" posX="2510.6899414063" posY="2778.3745117188" posZ="10.8203125" rot="270" skin="285"/>
</team1>
You could use the following code:
teamRed = getElementByID ( "red" ) -- find the parent element by it's ID count = getElementChildrenCount ( teamRed ) -- get the total number of children outputChatBox ( "Team red has " .. count .. " spawnpoints" ) -- output: Team red has 4 spawnpoints
