Is only the XML declaration the problem or are there more, e.g. multiple 
root elements?

Don't understand the last sentence.

You might need to put another ContentHandler into the pipe that just 
ignores startDocument() and endDocument():

ContentHandler myContentHandler = new MyContentHandler(this.contentHandler);
this.contentHandler.startDocument();
for (long i = 0; i < result.getSize(); i++)
{
     resource = (XMLResource)
     result.getResource(i);
     resource.getContentAsSAX(myContentHandler);
}
this.contentHandler.endDocument();


private class MyContentHandler implements ContentHandler {

     private ContentHandler ch;

     MyContentHandler(ContentHandler ch) {
         this.ch = ch;
     }

     startDocument() {
         //ignore
     }

     endDocument() {
         //ignore
     }

     allOtherMethodsFromContentHandler() {
         this.ch.allOtherMethodsFromContentHandler();
     }
}
