将json对象转化为xml、soap字符串

<script>
// 将json对象转化为xml
function toXml(obj){
var xml = "";
for(var k in obj){
var v = obj[k];
if(typeof(v)!="object"){
xml += "<" + k + ">" + v + "</" + k + ">";
}else{
xml += "<" + k + ">";
xml += toXml(v);
xml += "</" + k + ">";
}
}
return xml;
}

// 构建soap调用字符串
// name : 方法名称
// args : 附属json参数
// ns : 方法的namespace
function toSoap(name, args, ns)
{
var msg = '';
msg += '<v:Envelope\r\n';
msg += ' xmlns:i="http://www.w3.org/2001/XMLSchema-instance%22/r/n';
msg += ' xmlns:d="http://www.w3.org/2001/XMLSchema%22/r/n';
msg += ' xmlns:c="http://schemas.xmlsoap.org/soap/encoding/%22/r/n';
msg += ' xmlns:v="http://schemas.xmlsoap.org/soap/envelope/%22/r/n';
msg += ' >\r\n';
msg += ' <v:Header/>\r\n';
msg += ' <v:Body>\r\n';
msg += ' <' + name + ' xmlns="' + ns + '" id="o0" c:root="1">\r\n';
msg += ' ' + toXml(args) + "\r\n";
msg += ' </' + name + '>\r\n';
msg += ' </v:Body>\r\n';
msg += '</v:Envelope>\r\n';
return msg;
}

//var o = {a:1, b:"xx", c:{c1:3, c2:"ww"}};
//alert(toXml(o));
var o = {
zi_tid:'XQ9Fasfi+7wBswdfgsszCw==',
zi_isre:1,
key:null,
row:10,
skip:0,
code:'iJRgfsfsjQyO4'
};
var soap = toSoap('ListInfo', o, 'AuthorityServicewsdl');
alert(soap);
</script>

ps. 这段脚本在调用php的webservice时会用到（用标准的soap协议），aspnet的webservice既实现了标准的soap也实现了普通的get/post方式，调用简单很多。
