				By default, CDATA nodes in an XML file will be represented with CDATASection objects in a DOM document. This example demonstrates how to create a parser that converts CDATA nodes into text nodes. 
				    try {
				        // Create a builder factory
				        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
				    
				        // Configure it to coalesce CDATA nodes
				        factory.setCoalescing(true);
				    
				        // Create the builder and parse the file
				        Document doc = factory.newDocumentBuilder().parse(new File("infilename.xml"));
				    
				        // doc will not contain any CDATA 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 pretext
				        				        Some posttext
				    
				
				and output: 
				    
				    
				        Some pretext
				        Some text with lots of <"!@#$%'^&*()> special characters
				        Some posttext
