If you are using the JavaScript environment of a modern web browser, you can manipulate XML data as I explained here: Create XML in Javascript

If not, I recommend to use another XML DOM implementation for JavaScript, for example xmldom.

Let's suppose, xmlDoc is your XML document as an XML DOM object. To change the text CONSULT CHECKING SYSTEM to CONSULT CHECKING SYSTEM CONSULTAR EL SISTEMA DE CONTROL, you could retrieve the element node like this:

var name = xmlDoc.getElementsByTagName("name")[1];

and change the content like this:

name.textContent = "CONSULT CHECKING SYSTEM CONSULTAR EL SISTEMA DE CONTROL";
