下面分享一段程式碼例項，它實現了將xml檔案轉換為table表格格式的功能。

這裡不介紹它的實現過程，感興趣的朋友可以自己做一下分析。

程式碼如下:

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;
