Javascript 邮递员：如何在xml主机响应中解析CDATA中的xml？

我在这里和其他地方阅读了多个参考资料，但我未能解决我的问题

我用XML向主机发送一个POST请求，主机的CDATA由另一个XML“请求”组成，并且响应具有相同的结构。 从CDATA中的嵌套XML响应中，我需要提取一个属性（'ATTRIBUTE7'），它将成为Postman中的一个环境变量。 我的理解是，由于CDATA，VASDataString的内容被视为不应解析的文本块

我怎样才能超过这个街区

解决方案：

const xml2js = require('xml2js');
xml2js.parseString(pm.response.text(), (err, result) => {
    if (err) {
        console.error(err);
        return;
    }

    const body = result.VASMessage.Body[0].VASDataString[0];
    
    xml2js.parseString(body, (err, result) => {
        if (err) {
            console.error(err);
            return;

        pm.environment.set("ATTRIBUTE7",  JSON.stringify(result.HostMessage.PIPPO_RESPONSE[0].HostResponse[0].$.ATTRIBUTE7));
