This function is used to edit an attribute of a node in a configuration file.
Syntax
bool xmlNodeSetAttribute ( xmlnode xmlnode, string name, var value )
Required Arguments
- xmlnode: The node in which you wish to edit the attribute.
- name: The name of the attribute.
- value: The value which you wish to change the attribute to.
Returns
Returns true if edit was successful, false if the node and/or attribute do not exist, or if they're faulty.
Example
In a gamemode, we want a command to change the marker color in the configuration file.
config.xml:
<config>
<markers color="255,100,0" />
</config>
Lua code:
config = xmlLoadFile("config.xml")
function changeConfigMarkerColor(player, command, r, g, b)
markernode = xmlFindSubNode(config, "markers", 0)
xmlNodeSetAttribute(markernode, "color", r .. "," .. g .. "," .. b)
end
addCommandHandler("markercolor", changeConfigMarkerColor)
Note that this example only changes the in-memory XML document. If you want to save the changed document back to the hard drive, use xmlSaveFile.
