<?xml version="1.0" encoding="utf-8"?>
<names>
    <name id="7">a君</name>
    <name id="9">b君</name>
    <name id="10">c君</name>
<names>

　　/*
    # 读取文件
    # xml文档路径
    */
    this.loadXML = function(xmlFile){
        var xmlDoc;  
        var xmlhttp = new window.XMLHttpRequest();  
        xmlhttp.open("GET",xmlFile,false);  
        xmlhttp.send(null);  
        xmlDoc = xmlhttp.responseXML.documentElement;
        return xmlDoc;  
    }

$xml="<?xml version=\"1.0\" encoding=\"utf-8\"?>\r\n";
$xml.="<names>\r\n";
while($row = mysql_fetch_array($res))
{
   $xml.= "<name id=‘".$row[‘uid‘]."‘>".$row[‘cname‘]."</name>\r\n";
}
 
$xml.= $tmp."</names>"

$xml.= "<name id=\"".$row[‘uid‘]."\">".$row[‘cname‘]."</name>\r\n";
