如何使用DOM解析器从XML文件中读取注释

Question

我正在尝试阅读XML文件中的注释.使用DOM解析后无法获取注释节点.

码:

DocumentBuilderFactory docBldrFactry = DocumentBuilderFactory.newInstance();
docBldrFactry.setIgnoringComments(false);
DocumentBuilder docBuilder = docBldrFactry.newDocumentBuilder();
Document document = docBuilder.parse(new File("C:\\webser.xml"));
Element rootElement = document.getDocumentElement();
NodeList list = rootElement.getElementsByTagName("Bean");

评论在Bean元素下.当我循环遍历Bean元素的子节点时,我没有得到注释节点.

这是XML

<Beans>
  <Bean>
    <!-- Testing Comments -->
    <API name ="xyz" />
  </Bean>
</Beans>

希望这可以帮助 :)

XMLStreamReader xr = XMLInputFactory.newInstance().createXMLStreamReader(new FileInputStream("file.xml")); 
while (xr.hasNext()) {
    if (xr.next() == XMLStreamConstants.COMMENT) {
        String comment = xr.getText();
    } }
