JavaScript method to convert xml into html table_javascript skills

function ConvertToTable(targetNode)
{
 // if the targetNode is xmlNode this line must be removed
 // i couldnt find a way to parse xml string to xml node
 // so i parse xml string to xml document
 targetNode = targetNode.childNodes[0];
 // first we need to create headers
 var columnCount = targetNode.childNodes[0].childNodes.length;
 var rowCount = targetNode.childNodes.length
 // name for the table
 var myTable = document.createElement("table");
 myTable.border = 1;
 myTable.borderColor ="green";
 var firstRow = myTable.insertRow();
 var firstCell = firstRow.insertCell();
 firstCell.colSpan = columnCount;
 firstCell.innerHTML = targetNode.nodeName;
 // name for the columns
 var secondRow = myTable.insertRow();
 for(var i=0;i<columnCount;i++)
 {
  var newCell = secondRow.insertCell();
  newCell.innerHTML = targetNode.childNodes[0].childNodes[i].nodeName;
 }
 // now fill the rows with data
 for(var i2=0;i2<rowCount;i2++)
 {
  var newRow = myTable.insertRow();
   for(var j=0;j<columnCount;j++)
   {
   var newCell = newRow.insertCell();
   newCell.innerHTML = targetNode.childNodes[i2].childNodes[j].firstChild.nodeValue;
   }
 }
 // i prefer to send it as string instead of a table object
 return myTable.outerHTML;
}
