Server

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(thePlayer, command, r, g, b)
    local 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.
