直接上代码~
在网上找了很多例子，大多数不适用，而且麻烦，自己进行了一些调整，完成了一个可以区分大小写的json转xml的小功能~
功能实现js：
???function CreatXmlDoc(obj){ ???????this.tagName=obj.tagName; ???????this.properties = obj.properties; ???????var children=obj.children.map(function(item){ ???????????if(typeof item =="object") ???????????{ ??????????????item=new CreatXmlDoc(item) ???????????} ???????????return item ???????}) ???????this.children=children; ???} ????????function loadXMLDoc(dname) { ???????try {//Internet Explorer ???????????xmlDoc = new ActiveXObject("Microsoft.XMLDOM"); ???????} catch(e) { ???????????try {//Firefox, Mozilla, Opera, etc. ???????????????xmlDoc = document.implementation.createDocument("", "", null); ???????????} catch(e) { ???????????????alert(e.message) ???????????} ???????} ???????return xmlDoc; ???} ????CreatXmlDoc.prototype.render=function(){ ???????xmlDoc = loadXMLDoc(); ???????var xe1 = xmlDoc.createElement(this.tagName); ???????for(var p in this.properties){ ???????????xe1.setAttribute(p, this.properties[p]); ???????} ???????var children=this.children || []; ???????children.forEach(function(child){ ???????????var childEl=(child instanceof CreatXmlDoc) ???????????? child.render() ???????????:xmlDoc.createTextNode(child) ???????xe1.appendChild(childEl); ???????}) ???????return xe1; ???}
// 封装调用函数// 将json转成xml文档，再转成字符串var xmlToString = function(eleJson) { ???var doc=new CreatXmlDoc(eleJson); ???SetupSerial=(new XMLSerializer()).serializeToString(doc.render()); ???var reg = new RegExp(‘ xmlns="http://www.w3.org/1999/xhtml"‘,"g"); ???// 替换转义字符 ???var reg1 = new RegExp(‘<‘,"g"); // < ???var reg2 = new RegExp(‘>‘,"g"); // > ???var reg3 = new RegExp(‘&‘,"g"); // & ???var reg4 = new RegExp(‘'‘,"g"); // ‘ ???var reg5 = new RegExp(‘"‘,"g"); // " ???SetupSerial=SetupSerial.replace(reg,"").replace(reg1, "<").replace(reg2, ">").replace(reg3, "&").replace(reg4, "‘").replace(reg5, ‘"‘); ???return SetupSerial;}准备工作完成后就可以使用了！
示例：
var obj={ tagName:‘Setup‘, ???properties:{ ???????type:"text", ???????name:"hahha", ???????title:"哈哈" ???}, children:[ { tagName:‘ProtocolList‘, children:[ { tagName:‘Protocol‘, children:[ { tagName:‘Name‘, children:["onvif"] }, { tagName:‘UserName‘, children:["admin"] }, { tagName:‘PassWord‘, children:["admin"] }, { tagName:‘Port‘, children:["8000"] }, { tagName:‘MediaPort‘, children:["8000"] }, ] }, { tagName:‘Protocol‘, children:[ { tagName:‘Name‘, children:["onvif"] }, { tagName:‘UserName‘, children:["admin"] }, { tagName:‘PassWord‘, children:["admin"] }, { tagName:‘Port‘, children:["8000"] }, { tagName:‘MediaPort‘, children:["8000"] }, ] }, { tagName:‘Protocol‘, children:[ { tagName:‘Name‘, children:["onvif"] }, { tagName:‘UserName‘, children:["admin"] }, { tagName:‘PassWord‘, children:["admin"] }, { tagName:‘Port‘, children:["8000"] }, { tagName:‘MediaPort‘, children:["8000"] }, ] }, ] }, { tagName:‘Function‘, children:[ { tagName:‘PlayBack‘, children:["onvif"] }, { tagName:‘Other‘, children:["rtsp"] } ] } ] }SetupSerial = xmlToString(obj);console.log(SetupSerial);输出结果：
<Setup type="text" name="hahha" title="哈哈"> ???<ProtocolList> ???????<Protocol> ???????????<Name>onvif</Name> ???????????<UserName>admin</UserName> ???????????<PassWord>admin</PassWord> ???????????<Port>8000</Port> ???????????<MediaPort>8000</MediaPort> ???????</Protocol> ???????<Protocol> ???????????<Name>onvif</Name> ???????????<UserName>admin</UserName> ???????????<PassWord>admin</PassWord> ???????????<Port>8000</Port> ???????????<MediaPort>8000</MediaPort> ???????</Protocol> ???????<Protocol> ???????????<Name>onvif</Name> ???????????<UserName>admin</UserName> ???????????<PassWord>admin</PassWord> ???????????<Port>8000</Port> ???????????<MediaPort>8000</MediaPort> ???????</Protocol> ???</ProtocolList> ???<Function> ???????<PlayBack>onvif</PlayBack> ???????<Other>rtsp</Other> ???</Function></Setup>
大功告成！
