Did you or anyone else ever manage to do this in the end?

I am also not finding a solution for this seemingly easy task. Just save data to multiple xml files....

Any help appreciated!

1. for (int count = 0; count < 4; count++)
   {
     String xmlFilename = "xmlFile"+count+".xml";
2.   xmlOutputFile = createWriter(xmlFilename);
     //xml header info
     xmlOutputFile.println("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");
     //xml contents
     //xmlOutputFile.println(contents);
     //don't forget your closing tags!
     xmlOutputFile.flush();
     xmlOutputFile.close();
   }
   

Thanks alot for your answer. I actually didn't know that one could write XML that easy (thanks for the hint, that sure will come handy at some point!), but it hasn't really helped me, since I need a little more advanced writing tools (like add childs or something to an existing xml file etc.), that the proXML library offers.

BUT, I found the solution how to write to multiple xml files with the proXML library.

I found it on this code http://ericbrotto.com/EricBrotto/data/source/:

A seperate class (here: info) has to be introduced so the multiple xmlEvent() calls don't screw each other up.

The important parts are here: 

1. import proxml.*; 
   
   XMLInOut xml = null;                                  // Two separate xml objects. One for the photos, one for info on the photos
   XMLInOut infoXml = null; 
   //....
   
   Info info = new Info();                                // A separate class is needed to run a second xml loadEvent/saveElement method.                         
   
   void setup() { 
   
     //....
     xml = new XMLInOut(this);                            // The two xml objects instantiated
     infoXml = new XMLInOut(this,info);
   
   
   }  
   
   void draw() {  
   
   
   
   }  
   
   void xmlEvent(proxml.XMLElement _x) { 
     parseXML(_x); 
   } 
   
   
   public class Info { 
   
   void xmlEvent(proxml.XMLElement _x) { 
     parseXML(_x); 
   }
