String对象与xml文档对象的互相转换

String对象与xml文档对象的相互转换

经常遇到在js里面需要解析xml的问题，然而有时候，后台返回的不是dom 而是string 字符串，需要将字符串转换成dom对象，然后才可以进行节点值解析和读取

?

var? bankXml = '<root><bank>工行</bank><bankId>101011110</bankId></root>'

?

var bankDom = createXml(bankXml);

?

//将字符串转化成dom对象? add by lc 20101203
function createXml(str){

?if(document.all){
??? var xmlDom = new ActiveXObject("Microsoft.XMLDOM");
??? xmlDom.loadXML(str);
??? return xmlDom;
?}else
??? return new DOMParser().parseFromString(str,"text/xml");
}
