java - Stax 未检测到结束元素

Question

我正在读取与下面相同的 XML 文件:

<ts>
    <tr comment="" label="tr1">
        <node order="1" label="" />
    </tr>
</ts>

我希望下面的代码打印出三个 e在屏幕上:

XMLInputFactory factory = XMLInputFactory.newInstance();
XMLStreamReader sr = factory.createXMLStreamReader(new FileReader("test.xml"));

while (sr.hasNext()) {
    int eventType = sr.next();

    if (eventType == XMLStreamReader.START_DOCUMENT) {
        continue;
    } else if (eventType == XMLStreamReader.END_ELEMENT) {
        System.out.println("e");
    } else if (eventType == XMLStreamReader.START_ELEMENT) {
        System.out.println("s");
    }
}

但是没用!关于如何解决问题的任何想法？

注意:我觉得是跟self-closed-tags有关，比如:<myTag id="1" />

Answer 1

我在 Windows 上使用 JDK 1.7，得到的结果与 Blaise Doughan 相同:

s
s
s
e
e
e

我认为这与 <node order="1" label="" /> 无关自 documentation指出:

NOTE: empty element (such as <tag/>) will be reported with two separate events: START_ELEMENT, END_ELEMENT - This preserves parsing equivalency of empty element to <tag></tag>. This method will throw an IllegalStateException if it is called after hasNext() returns false.

远景:也许其他一些相关代码可能会导致奇怪的行为？
