How to traverse through every tag

[Vetagiri-Hrushikesh]

Hello Team
I have an xml something structured like this. I can loop through only var tags if I use this code given below. I need everything which is inside message in order. Can someone please help me with this?

<data>
    <message>
        <var />
        <var />
        <bitfield>
                <bit />
                <bit />
                <bit />
        </bitfield>
        <var />
        <var />
        <var />
        <var />
       <bitfield>
                <bit />
                <bit />
                <bit />
                <bit />
                <bit />
                <bit />
        </bitfield>
    </message>
</data>

    fetch('../assets/filename.xml').then((response) => {
      response.text().then((xml) => {
        let result1 = converter.xml2json(xml, { compact: true, spaces: 4});
        const JSONData = JSON.parse(result1);
        // console.log(JSONData);
        let list: any = [];
        list = Array.isArray(JSONData.data.message.var) ? JSONData.data.message.var : [];
        for (let i of list) {
          let varTag = {
            addr: i._attributes.addr ? i._attributes.addr : '',
            len: i._attributes.len ? i._attributes.len : '',
            name: i._attributes.name ? i._attributes.name : '',
          }
          this.list.push(varTag);
        }
        console.log(this.list);
      });
    });
