本文向大家介绍JavaScript实现将xml转换成html table表格的方法，包括了JavaScript实现将xml转换成html table表格的方法的使用技巧和注意事项，需要的朋友参考一下

本文实例讲述了JavaScript实现将xml转换成html table表格的方法。分享给大家供大家参考。具体如下：

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;
 // 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;
}

下面是一个简单的示例用法：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head>
 <title>Untitled Page</title>
</head>
<body>
<script type="text/javascript">
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;
}
function loadXmlDocFromString(text)
{
 try //Internet Explorer
  {
  xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
  xmlDoc.async="false";
  xmlDoc.loadXML(text);
  return xmlDoc;
  } 
 catch(e)
  {
  try // Firefox, Mozilla, Opera, etc.
  {
  parser=new DOMParser();
  xmlDoc=parser.parseFromString(text,"text/xml");
  return xmlDoc;
  }
  catch(e)
  {
  alert(e.message);
  return;
  }
  }
}
var myXml = '<TableName> \
  <firstRow> \
  <field1>1</field1> \
  <field2>2</field2> \
  </firstRow> \
  <firstRow> \
  <field1>3</field1> \
  <field2>4</field2> \
  </firstRow> \
 </TableName>';
 var myDoc = loadXmlDocFromString(myXml);
document.write( ConvertToTable(myDoc));
</script>
</body>
</html>
