How to parse a String to ivy xml-object?

Question

I receive a string from an external java class which is an xml-file. How can I parse this to an ivy-xml object? (Xpert.ivy 4.3)

The following ivyScript parses an xml stored in string to an ivy-xml object:

String xmlDocument = "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?> <role> <identifier>Everybody</identifier> </role>";
Xml xml = new Xml(xmlDocument);

Which import(s) is/are necessary? I get an class Xml not found message. I've used a different approach using the DocumentBuilder. So I get an xml-Object which is no ivy-object which is actually fine for me. Ah - just to mention - this project is in an 4.3 environment. Beside that - is the role node necessary or was this just an example?

There is no import necessary because Xml is a standard Xpert.ivy data type. The xml in xmlDocument is an expamle. Your Xml will look different of course. I have written the example code in Xpert.ivy 5. But it should also work in 4.3.

True. Don't know what was wrong - copy&paste is sometimes a really difficult task for me. ;)

If an XML-Object (not an ivy-scripting object) is fine for you - which works in my case - I used the following approach:

import java.io.StringReader;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Document;
import org.w3c.dom.NodeList;
import org.xml.sax.InputSource;

[...]
String xmlString = geoCode.getXML();

DocumentBuilderFactory dbfac = DocumentBuilderFactory.newInstance();
DocumentBuilder db;

db = dbfac.newDocumentBuilder();
Document xmlDoc = db.parse(new InputSource(new StringReader(xmlString)));
[...]
