将XML转换为Json。并获取特定数据(Javascript)

const parser = new DOMParser();
const xmlDoc = parser.parseFromString(xmlString, "text/xml");

function xmlToJson(xml) {
  const result = {};

  if (xml.nodeType === 1) {
    // 节点类型为元素节点
    if (xml.attributes.length > 0) {
      result["@attributes"] = {};
      for (let i = 0; i < xml.attributes.length; i++) {
        const attribute = xml.attributes[i];
        result["@attributes"][attribute.nodeName] = attribute.nodeValue;
      }
    }
  } else if (xml.nodeType === 3) {
    // 节点类型为文本节点
    result = xml.nodeValue;
  }

  if (xml.hasChildNodes()) {
    for (let i = 0; i < xml.childNodes.length; i++) {
      const child = xml.childNodes[i];
      const nodeName = child.nodeName;
      if (result[nodeName] === undefined) {
        result[nodeName] = xmlToJson(child);
      } else {
        if (!Array.isArray(result[nodeName])) {
          result[nodeName] = [result[nodeName]];
        }
        result[nodeName].push(xmlToJson(child));
      }
    }
  }

  return result;
}

const jsonData = xmlToJson(xmlDoc);

const jsonString = JSON.stringify(jsonData);
