				By default, Comment nodes are created for each comment in an XML file. If it is not necessary to preserve the comments, there is no need to create the nodes. This example demonstrates how to create a parser that ignores comments. 
				    try {
				        // Create a builder factory
				        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
				    
				        // Configure it to ignore comments
				        factory.setIgnoringComments(true);
				    
				        // Create the builder and parse the file
				        Document doc = factory.newDocumentBuilder().parse(new File("infilename.xml"));
				    
				        // doc will not contain any Comment nodes
				    } catch (SAXException e) {
				        // A parsing error occurred; the xml input is not valid
				    } catch (ParserConfigurationException e) {
				    } catch (IOException e) {
				    }
				
				Here's some sample input: 
				    
				    
				    
				        Some text
				        
				        Some text
				    
				    
				
				and output: 
				    
				    
				        Some text
				    
				        Some text
