This function is used to edit an attribute of a node in a configuration file.

Syntax

bool xmlNodeSetAttribute ( xmlnode node, string name, string/float value )             

Required Arguments

  • node: The node of which you wish to edit an attribute.
  • name: The name of the attribute.
  • value: The value which you wish to change the attribute to.

Returns

Returns true if the attribute was set successfully, false if the node and/or attribute do not exist, or if they're faulty.

Example

Click to collapse [-]
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.
