html怎么读取xml里的数据,第1张

html代码如下:

<html>

<head>

<title>html读取xml数据实例一</title>

</head>

<body>

<xml id="xx" src="table.xml">

</xml>

<h3>html读取xml数据实例一</h3>

<table datasrc="#xx" border="1">

<thead> <th>序号</th> <th>区域</th> <th>名字</th> <th>电话</th> <th>QQ</th> <th>email</th>

</thead>

<tr>

<td><span datafld="nid"></span></td>

<td><span datafld="area"></span></td>

<td><span datafld="salename"></span></td>

<td><span datafld="phone"></span></td>

<td><span datafld="qq"></span></td>

<td><span datafld="email"></span></td>

</tr>

</table>

</body>

</html>

xml文件如下:

<?xml version="1.0"?>

<!DOCTYPE tables[

<!ELEMENT tables (table)*>

<!ELEMENT table(nid, area, salename, phone,qq,email)>

<!ELEMENT nid (#PCDATA)>

<!ELEMENT area (#PCDATA)>

<!ELEMENT salename (#PCDATA)>

<!ELEMENT phone (#PCDATA)>

<!ELEMENT qq (#PCDATA)>

<!ELEMENT email (#PCDATA)>

]>

<tables>

<table>

<nid>1</nid>

<area>广东深圳</area>

<salename>张XX</salename>

<phone>0755-265XXXX1,1382XXX409</phone>

<qq>12XXX88</qq>

<email>TSXXX@c-sct.com</email>

</table>

<table>

<nid>1</nid>

<area>广东深圳</area>

<salename>张XX</salename>

<phone>0755-265XXXX1,1382XXX409</phone>

<qq>12XXX88</qq>

<email>TSXXX@c-sct.com</email>

</table>

<table>

<nid>1</nid>

<area>广东深圳</area>

<salename>张XX</salename>

<phone>0755-265XXXX1,1382XXX409</phone>

<qq>12XXX88</qq>

<email>TSXXX@c-sct.com</email>

</table>

</tables>

对读取的xml格式的数据 用 $(xxx).html() 时找不到 innerHTML对象 , 发现此时读取的XML数据为字符串,不是DOM对象[jQuery库]

所以:

ReadXml("1.xml")

function ReadXml(url){

    $.get(url, function(d){

         var xmlDoc = new ActiveXObject("Microsoft.XMLDOM")

         xmlDoc.async = false

         if( !xmlDoc.load(d) ){ alert(" 载入失败!")return false}

         var objE = document.createElement("div")

         objE.innerHTML = xmlDoc.xml

         return objE 

    }

}

可以用javascript读取xml数据

实例如下:

首先:xml文件(tree.xml)内容如下:

<?xml version="1.0" encoding="gb2312"?>

<treeview>

<tree id="p1">

<text>山东省</text>

<target>_blank</target>

<title>省份</title>

<link></link>

<tree id="p1-1">

<text>威海市</text>

<target>_blank</target>

<title>城市</title>

<link></link>

</tree>

<tree id="p1-2">

<text>烟台市</text>

<target>_blank</target>

<title>城市</title>

<link></link>

<node id="p1-2-1">

<text>长夼村</text>
