How to write a XML file?
Jun 27th, 2009, 1:37pm  
Hi,
I am doing a cellular automata analysis and like to store my data
into a XMLfile for further use.
I thought it was a good idea to store the data inside XMLElement.
Now I like to save the XML to a file. I discovererd the XMLWriter class inside the developers api documentation...
but how does it work?

Here is my poor try:


XMLElement fieldofbasins= new XMLElement();
fieldofbasins.setName("FieldOfBasins");
fieldofbasins.setAttribute( "Parameter","0815");
fieldofbasins.setContent("inhalt");

// file schreiben
PrintWriter xmlfile;
String feld = "HalloWelt";
xmlfile = createWriter(feld+".xml");

println(fieldofbasins.getName());
print(fieldofbasins.getContent());

//xml schreiben
XMLWriter schreibXML = new XMLWriter(xmlfile) ;

schreibXML.write(fieldofbasins);

xmlfile.flush();
xmlfile.close();


Perhaps somebody could help, plz

thx
Alexander

Unhandled exception means you need to add a try/catch block around the code needing it.
Processing insulates most of its API from these exceptions (sometime too much, I think) but not there.
Code you must change:
Code:
//xml schreiben
try
{
XMLWriter schreibXML = new XMLWriter(xmlfile) ;

schreibXML.write(fieldofbasins);

xmlfile.flush();
xmlfile.close();
}
catch (IOException e)
{
  e.printStackTrace();
}
