NEWBIE Blonde moment!

I have a xml document (static) that I need to test what is in a grand child element. The real application is a jqGrid. I have a onSelectRow operation going on. I can click on a row and get a response (in a alert window) for any root children. But how do I do this for anything deeper in the tree? A portion of my xml is attached.

Here is my onSelectRow function:

1. onSelectRow: function() {
   var gsr = $('#searchResults').jqGrid('getGridParam', 'selrow');
   if (gsr) {
   var data = $('#searchResults').jqGrid('getRowData', gsr);
   $('#basicMun h3').append("DODIC: " + data.dodic + "Nomenclature: " + data.nomenclature),
   .append("Use: " + data.use + "Description: " + data.description)
   .append("Length: " + data.objLength + "Width: " + data.objWidth);
   alert(data.performance > velocity > unit);
   }
   }
   
   
   
   
   
   
   
   
   
   

I can always get a response in the alert box when I access things like dodic, nomenclature, use, etc. But my code breaks/freezes when I try and target things such as <unit> within elements like <objLength>. I have tried the above alert line and also alert(data.objLength.unit);, but neither one works.
