Any idea how to put a line break between tags in xml when used as map markers? Thanks

[deucalion0]

Hey guys I have created an xml file which holds all my google map api markers information. The markers are all in tags called marker and I have 6 sets, and I want a line break between the 6 sets. The markers are activated by links which are activated whne checkboxes are clicked, but so far when all checkboxes are clicked the whole bunch of links appear one after another I need a space between them. I tried to do this in the javascript but could only get a line break between every marker not the sets which is no use, then I set blank markers in between the sets, this worked put put marjers in at the top left of the map, again no use.

Here is the javascript code:

function initialize() {
   if (GBrowserIsCompatible()) {
      window.gmarkers = [];
      var gicons = [];

      var baseIcon = new GIcon(G_DEFAULT_ICON);
      baseIcon.iconAnchor = new GPoint(9,34);
      baseIcon.iconSize = new GSize(20,34);
      baseIcon.infoWindowAnchor = new GPoint(9,2);

		
      // A function to create the marker and set up the event window
      function createMarker(point,name,html,category) {
        var marker = new GMarker(point,gicons[category]);
        // === Store the category and name info as a marker properties ===
        marker.mycategory = category;                                 
        marker.myname = name;
        GEvent.addListener(marker, "click", function() {
          marker.openInfoWindowHtml(html);
        });
        window.gmarkers.push(marker);
        return marker;
      }

      // == shows all markers of a particular category, and ensures the checkbox is checked ==
      function show(category) {
        for (var i=0; i<window.gmarkers.length; i++) {
          if (window.gmarkers[i].mycategory == category) {
            window.gmarkers[i].show();
          }
        }
        // == check the checkbox ==
        document.getElementById(category+"box").checked = true;
      }

      // == hides all markers of a particular category, and ensures the checkbox is cleared ==
      function hide(category) {
        for (var i=0; i<window.gmarkers.length; i++) {
          if (window.gmarkers[i].mycategory == category) {
            window.gmarkers[i].hide();
          }
        }
        // == clear the checkbox ==
        document.getElementById(category+"box").checked = false;
        // == close the info window, in case its open on a marker that we just hid
        map.closeInfoWindow();
      }

      // == a checkbox has been clicked ==
     function boxclick(category) {
    var box = this;
    var category = box.id.substr(0, box.id.length - 3);
    if (box.checked) {
          show(category);
        } else {
          hide(category);
        }
        // == rebuild the side bar
        makeSidebar();
      }

document.getElementById('bandsbox').onclick = boxclick;
document.getElementById('panteramembersbox').onclick = boxclick;
document.getElementById('rammsteinmembersbox').onclick = boxclick;
document.getElementById('cobmembersbox').onclick = boxclick;
document.getElementById('inflamesmembersbox').onclick = boxclick;
document.getElementById('machineheadmembersbox').onclick = boxclick;



      // == rebuilds the sidebar to match the markers currently displayed ==
      function makeSidebar() {
        var html = "";
        for (var i=0; i<window.gmarkers.length; i++) {
          if (!window.gmarkers[i].isHidden()) {
            html += '<a href="javascript:myclick(' + i + ')">' + window.gmarkers[i].myname + '<\/a><br>';
          }
        }
        document.getElementById("side_bar").innerHTML = html;
      }


      // create the map
      var map = new GMap2(document.getElementById("map"));
      map.addControl(new GLargeMapControl());
      map.addControl(new GMapTypeControl());
      map.setCenter(new GLatLng(55.7465,-40.4629), 2);


      // Read the data
      GDownloadUrl("categories.xml", function(doc) {
        var xmlDoc = GXml.parse(doc);
        var markers = xmlDoc.documentElement.getElementsByTagName("marker");
          
        for (var i = 0; i < markers.length; i++) {
          // obtain the attribues of each marker
          var lat = parseFloat(markers[i].getAttribute("lat"));
          var lng = parseFloat(markers[i].getAttribute("lng"));
          var point = new GLatLng(lat,lng);
         var address = markers[i].getAttribute("address");
var name = markers[i].getAttribute("name");
var html = markers[i].getAttribute("html");
var html = "<b>"+name+"<\/b><p>"+address+"</p>"+html;
var category = markers[i].getAttribute("category");
          // create the marker
          var marker = createMarker(point,name,html,category);
          map.addOverlay(marker);
        }

        // == show or hide the categories initially ==
        show("bands");
        hide("panteramembers");
         hide("rammsteinmembers");
		  hide("rammsteinmembers");
		   hide("cobmembers");
		    hide("inflamesmembers");
			hide("machineheadmembers");
        // == create the initial sidebar ==
        makeSidebar();
      });
    }

    else {
      alert("Sorry, the Google Maps API is not compatible with this browser");
    }

}

  function myclick(i) {
        GEvent.trigger(window.gmarkers[i],"click");
      }

here is some of the xml which i need split up:
