How use XML-Parser in Web Dypro (how get filename)

Question

Hi everybody,
i want to use the saxparser to read a xml-file via a Fileupload-UI element. In Web Dynpro it is not possible to get the path of a file which was on a client through the Fileupload-UI. So how can i use a xml-parser when i have to give it the file name?
Is it possible to use the "resource" of the Fileupload-UI instead ot the filename? How can i call the parser?
                    SAXParser saxParser= null;
     try{                   
          SAXParserFactory factory = SAXParserFactory.newInstance();               
          saxParser = factory.newSAXParser();               
          saxParser.parse( new File(??????), new  Gaeb());
     }catch (Exception ex){
          ex.printStackTrace();

Hi Siarhei,
i bind the resource property to my context of type IWDResource, the xml-file is now uploaded to KM-Content : /documents/GSW/Upload_UT_Sample_A.xml.
I create with resource.getURL() the path of the xml-file and give it to my xml-parser class, but i cannot get any value
from my parser (value returns "null"). Now i don't know if i have a mistake in creating the path of my file or a mistake in my parser??
Could you please have a look to my  source code:
I try to get the path with:
       /* Get Path of "/documents/GSW/XML/Upload_UT_Sample_A.xml" */
       String urlToFile = resource.getUrl(WDFileDownloadBehaviour.AUTO.ordinal());                  
      /* Call the Parser Class with path*/
      MyXMLParser myParser= new MyXMLParser ( urlToFile );
      /* Get one value from xml-class*/
      wdComponentAPI.getMessageManager().reportSuccess("Value: " + myParser.getValue());  <-- returns "null"     
My XML-Class:
public class MyXMLParser extends DefaultHandler {
     private String path = null;
     private String fName = null;
     public  String lValue;     
     private boolean lSupplier = false;
     private boolean lQuoteNumber = false;     
     public Gaeb(){ }
     public Gaeb(String path){
          SAXParserFactory factory = null;                         
          SAXParser saxParser = null;
          try {
               factory = SAXParserFactory.newInstance();                         
               saxParser = factory.newSAXParser();               
               saxParser.parse( path , new MyXMLParser () );     <-- i try also new File(path) instead of path.          
          }     catch (Exception ex){               
               ex.printStackTrace();
     public void startElement(String uri, String localName,
          String qName, Attributes attributes)
          throws SAXException {     
          lSupplier = true;        
     public void characters(char[] ch, int start, int length)
          throws SAXException {
          if (lSupplier){
               this.lValue = new String (ch,start,length);
     public String getValue(){
          return this.lValue;

Sid
