e515. Ignoring Comments While Parsing an XML FileBy 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: <?xml version="1.0" encoding="UTF-8"?> <!-- comment --> <root> Some text <!-- comment --> Some text </root> <!-- comment -->and output: <?xml version="1.0" encoding="UTF-8"?> <root> Some text Some text </root>
