在线javascript/js格式化xml代码

代码如下：​​​​ 

function formatXml(xml) {
    var formatted = '';
    var reg = /(>)(<)(\/*)/g;
    xml = xml.replace(reg, '$1\r\n$2$3');
    var pad = 0;
    $.each(xml.split('\r\n'), function (index, node) {
        var indent = 0;
        if (node.match(/.+<\/\w[^>]*>$/)) {
            indent = 0;
        } else if (node.match(/^<\/\w/)) {
            if (pad != 0) {
                pad -= 1;
            }
        } else if (node.match(/^<\w[^>]*[^\/]>.*$/)) {
            indent = 1;
        } else {
            indent = 0;
        }

        var padding = '';
        for (var i = 0; i < pad; i++) {
            padding += '  ';
        }

        formatted += padding + node + '\r\n';
        pad += indent;
    });
    return formatted;
}
