如何将XML节点转换为字符串? [英] How do I convert XML nodes to string?

问题描述

我的XML字符串如下:

I've such a xml string as following:

str = "<myxml><Node id="1" attr1="a" attr2="b" />
<Node id="2" attr1="a" attr2="b" /><Node id="3" attr1="a" attr2="b" />
<Node id="4" attr1="a" attr2="b" /></myxml>"

function returnNodeAsStr(str) {
...
...
}

if(returnNodeAsStr(str) == '<Node id="1" attr1="a" attr2="b" />') {
    alert("ok");
}

如何编写函数以将节点获取为字符串?(使警报执行)

How to write a function to get the node as string?(make the alert execute)

推荐答案

尝试一下:

var str = '<myxml><Node id="1" attr1="a" attr2="b" /><Node id="2" attr1="a" attr2="b" /><Node id="3" attr1="a" attr2="b" /><Node id="4" attr1="a" attr2="b" /></myxml>';

function returnNodeAsStr(str) {
    var xmlDoc = $.parseXML(str),
        xml = $( xmlDoc ),
        item=[],
        results=[];
    $(xml).find('Node').each(function() {
        item.push("<Node");
        $.each(this.attributes, function(i, attrib){
            item.push(attrib.name+"=\""+attrib.value+"\"");
        });
        item.push("/>");
        results.push(item.join(" "));
        item=[];
    });
    return results;
}

var result=returnNodeAsStr(str);
console.log(result);
/*
["<Node id="1" attr1="a" attr2="b" />", 
"<Node id="2" attr1="a" attr2="b" />", 
"<Node id="3" attr1="a" attr2="b" />", 
"<Node id="4" attr1="a" attr2="b" />"] 
*/

if(result[0] == '<Node id="1" attr1="a" attr2="b" />') {
    alert("ok");
}
