js 将xml转换为table表格简单代码实例
分类：实例代码
下面分享一段代码实例，它实现了将xml文件转换为table表格格式的功能。
这里不介绍它的实现过程，感兴趣的朋友可以自己做一下分析。
代码如下:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="author" content="http://www.51texiao.cn/" />
<title>前端教程网</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){
//Internet Explorer
try {
xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async="false";
xmlDoc.loadXML(text);
return xmlDoc;
}
catch(e){
// Firefox, Mozilla, Opera, etc.
try{
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));
