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> 
   <book category="cooking"> 
       <title lang="en">Everyday Italian</title>

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

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


module.exports = exampleParse

Congratulations, benvium, for your solution.

I already a lot of search one clean solution and one effective code, however your code was the only one that run with sucess (internet and others foruns). I get up this alert to all the programers that how me, spent a long time searching a real solution that works.

Attention all the programers, i am using NodeJS 10.13 and the WebService was development using .NET 4.5.1 C # WCF ASMX. Below there are one slice from my code to help all the programers, that passed many time searching one effective solution:

This is inside the file React Native App.js, lets go:

componentDidMount() {

    axios.get('http://adresswebservice.net/Service.asmx/[email protected]')
    .then(response => {   
         
    var xmlBase = '<?xml version="1.0" encoding="UTF-8" ?><business><company>Code Blog</company><owner>Nic Raboy</owner><employee><firstname>Nic</firstname><lastname>Raboy</lastname></employee><employee><firstname>Maria</firstname><lastname>Campos</lastname></employee></business>';
    var XMLParser = require('react-xml-parser');
    var xml = new XMLParser().parseFromString(xmlBase); 
    
    window.DOMParser = require('xmldom').DOMParser;
    const parser = new DOMParser();
    const xmlDoc = parser.parseFromString(xmlBase);    
    Alert.alert('CHILD XML: '+xmlDoc.getElementsByTagName("company")[0].childNodes[0].nodeValue);

    })
    .catch(error => {      
      console.log(error);
    });
  } 

PS: The xmlBase need completed with your result request webservice

The result was the XML child value: Code Blog

Have a nice day and merry christmas.
