The class org.openestate.io.wis_it.WisItUtils provides a static createDocument() function to read XML data in wohnen-in-suedtirol.it format from a java.io.File, java.io.InputStream, java.lang.String or org.w3c.dom.Document into a org.openestate.io.wis_it.WisItDocument.
import java.io.File;
import org.openestate.io.wis_it.WisItDocument;
import org.openestate.io.wis_it.WisItUtils;
import org.openestate.io.wis_it.xml.ObjectType;
import org.openestate.io.wis_it.xml.WIS;
public class WisItReadingExample {
public static void main(String[] args) throws Exception {
if (args.length < 1) {
System.err.println("No file was specified!");
System.exit(1);
}
// read file into a WisItDocument
WisItDocument doc = WisItUtils.createDocument(new File(args[0]));
// convert WisItDocument into a Java object
WIS wis = doc.toObject();
// now we can access the XML content through ordinary Java objects
if (wis.getOBJEKTE() != null) {
for (ObjectType obj : wis.getOBJEKTE().getOBJEKT()) {
// get object nr
String objectNr = obj.getID();
// get german object description
String objectInfoDe = obj.getINFODE();
// get italian object description
String objectInfoIt = obj.getINFOIT();
// print object information to console
System.out.println("found object " +
"'" + objectNr + "': " + objectInfoDe + " / " + objectInfoIt);
}
}
}

The class org.openestate.io.wis_it.xml.WIS is equivalent to a <WIS> root element in a wohnen-in-suedtirol.it document. For example the following code creates a wohnen-in-suedtirol.it document programmatically:

After a org.openestate.io.wis_it.xml.WIS object was created, it can be converted into a org.openestate.io.wis_it.WisItDocument with the static newDocument() function.
The class org.openestate.io.wis_it.WisItDocument provides a toXml() function, that finally writes the contents of the WIS object as XML into a java.io.File, java.io.OutputStream or java.io.Writer.
