Parse XML Example using React Native.xmldom is a pure JavaScript implementation of an XML Parser. I've added it to window so that browser modules that require it will work. Tested on iOS and Android.

react-native-parse-xml-example.js

/**
 *
 * Before use, type:
 * ```
 * npm install xmldom --save
 * ```
 */
window.DOMParser = require('xmldom').DOMParser;


const exampleParse = ()=> {
    const text = `<bookstore>

    const parser = new DOMParser();
    const xmlDoc = parser.parseFromString(text);

    console.log("XmlTest.exampleParse " + xmlDoc.getElementsByTagName("title")[0].childNodes[0].nodeValue);
};
