xml对象转json

xml文件先转成xml对象,再由xml对象转为JSON

// 10.10.0.99:8000/api/file/getFile//test/2011.xml
// 传路径
let LoadXMLFile = xmlFile => {
  let xmlDom = null;
  if (window.ActiveXObject) {
    xmlDom = new ActiveXObject("Microsoft.XMLDOM");
    //xmlDom.loadXML(xmlFile);//如果用的是XML字符串
    xmlDom.load(xmlFile); //如果用的是xml文件。
  } else if (document.implementation && document.implementation.createDocument) {
    let xmlhttp = new window.XMLHttpRequest();
    xmlhttp.open("GET", xmlFile, false);
    xmlhttp.send(null);
    xmlDom = xmlhttp.responseXML.documentElement;//一定要有根节点(否则google浏览器读取不了)
  } else {
    xmlDom = null;
  }
  return xmlDom;
}

let xmlToJson = xml => {
  // Create the return object
  let obj = {};
  // element
  if (xml.nodeType == 1) {
    // do attributes
    if (xml.attributes.length > 0) {
      obj["@attributes"] = {};
      for (var j = 0; j < xml.attributes.length; j++) {
        var attribute = xml.attributes.item(j);
        obj["@attributes"][attribute.nodeName] = attribute.nodeValue;
      }
    }
    // text
  } else if (xml.nodeType == 3) {
    obj = xml.nodeValue;
  }

  // do children
  if (xml.hasChildNodes()) {
    for (var i = 0; i < xml.childNodes.length; i++) {
      var item = xml.childNodes.item(i);
      var nodeName = item.nodeName;
      if (typeof (obj[nodeName]) == "undefined") {
        obj[nodeName] = xmlToJson(item);
      } else {
        if (typeof (obj[nodeName].push) == "undefined") {
          var old = obj[nodeName];
          obj[nodeName] = [];
          obj[nodeName].push(old);
        }
        obj[nodeName].push(xmlToJson(item));
      }
    }
  }
  return obj;
}

export {LoadXMLFile,xmlToJson}
