Load a map with geoxml using parseKmlString() and parse()

Question

OLD POST

How can I use parse and parseKmlString together?? I need show a map loading one KML file (I use parse(<kml_file>)) and two XML string (I use parseKmlString(<xml_string>)). How I use useTheData in afterParse property?? I don't know how I must manage this case. Can I use only one geoxml = new geoxml.parser() for three "layers"? How would I manage doc parameter in userTheData to get a "KML file layer" or "XML string layer"?

PD: Sorry for my english. It's very difficult to explain what I need.

I draw a map dinamically with ASP. If I get 3 layers, a write 3 object (geoxml_1, geoxml_2 and geoxml_3). It would be only one object, and show and hidden layer 1 or layer2.... That is my problem. Really it works, but it isn't fine code. When I load de map, it show all layers, and in a few seconds, only show the first layer and hidden the others. I would like whow only the first layer, an when I click the others layers in my buttons inside the map, it would show and hide de layers. This is my code (sorry, its too large):

function muestraCapasMapa(){
    var objCapa = document.getElementById("capas_mapa");
    var objFlecha = document.getElementById("flecha");
    if (objCapa.className=="ocultar"){
        objCapa.className = "";
        objFlecha.className = "plegar";
    }else{
        objCapa.className = "ocultar";
        objFlecha.className = "";
    }
}

PD: You can load the map using initialize_1(). It's too heavy, I hope it will for you to explain my problem better.

FINAL SOLUTION

I think I've found the solution to my problem. Finally I only create one geoXml object. I loaded four layers using parse(<url>):

<url_layer>/location.asp
<url_layer>/rute.asp?tip=1
<url_layer>/rute.asp?tip=2
<url_layer>/rute.asp?tip=3"

If you checked geoxml.docs.length you get 2!! So, if I show or hide the layer2 o layer3 could be wrong. The solution has been call to differents urls to get geoxml.docs.length==4:

<url_layer>/location.asp
<url_layer>/rute1.asp
<url_layer>/rute2.asp
<url_layer>/rute3.asp

Answer 2

This works for me:

geoXml = new geoXML3.parser({
               map: map,
               infoWindow: infowindow,
               singleInfoWindow: true
             });
geoXml.parse(filename);
geoXml.parse("TrashDays40.xml");
geoXml.parseKmlString('<kml xmlns="http://www.opengis.net/kml/2.2"><Document><Placemark><name><![CDATA[]]>Polygon</name><description><![CDATA[]]></description><Polygon><extrude>1</extrude><altitudeMode>relativeToGround</altitudeMode><outerBoundaryIs><LinearRing><coordinates>-93.46008301171878,31.329035778926478,0 -98.30505371484378,31.40065516914794,0 -97.37121582421878,30.106233605369603,0 -92.65808105859378,30.14749530904506,0</coordinates></LinearRing></outerBoundaryIs> </Polygon></Placemark></Document></kml>');
