java - java中解析XML文件解析换行问题

Question

    XMLInputFactory factory = XMLInputFactory.newInstance();
    Reader fileReader = new FileReader(xmlFileName);
    XMLEventReader reader = factory.createXMLEventReader(fileReader);

    while (reader.hasNext()) {
        XMLEvent event = reader.nextEvent();
        if (event.isStartElement()) {
            StartElement element = (StartElement) event;
            //process start element
        }
        if (event.isEndElement()) {
            currentParent = (DefaultMutableTreeNode)(currentParent.getParent());
            //process end element
        }
        if (event.isCharacters()) {
            Characters characters = (Characters) event;
            String text = characters.getData();
            if(text.startsWith("\n") || text.startsWith("\r\n") || text.startsWith("\r")) {
                continue;
            }

            //process characters element
        }

上面代码的问题是，在处理 XML 文件时，新行被作为字符节点处理，我希望有一个特定的标志来忽略新行。请告诉我这是否可行。

根据 the specification除非另有说明，否则必须保留空格:

An XML processor MUST always pass all characters in a document that are not markup through to the application.
