我想将它解析为Map数据结构，如下所示：
[{/PayrollFormInfo/FormInfo[1]/ExportDataVersion[1]=100},{/PayrollFormInfo/FormInfo[1]/QBVersion[1]=IFSP},{/PayrollFormInfo/FormInfo[1]/FormSetID[1]=FSDYF},{/PayrollFormInfo/FormInfo[1]/FormID[1]=INWKS941}, etc...]
注意在XML中有重复的元素节点，因此它们的出现顺序用括号[出现次数]来表征。
我很困惑如何解决这个问题。这似乎是一件简单的事情，但是我很难解决这个问题，我不确定我做错了什么。
以下是我在Java代码中所做的事情：
@Test
public void testP() throws Exception, FactoryConfigurationError, Exception {
File f = new File("xmlDir/example.xml");
Map<String,String> map = p(f);
logger.debug("CONTENTS OF MAP: "+Arrays.toString(map.entrySet().toArray()));
}
public Map<String, String> p(File file) throws Exception {
Map<String, String> map = new LinkedHashMap<String,String>();
XMLStreamReader xr = XMLInputFactory.newInstance().createXMLStreamReader(new FileInputStream(file));
while(xr.hasNext()) {
int e = xr.next();
if (e == XMLStreamReader.START_ELEMENT) {
String name = xr.getLocalName();
xr.next();
String value = null;
try {
value = xr.getText().trim();
} catch (IllegalStateException exep) {
exep.printStackTrace();
}
if (value != null && !value.isEmpty()) {
map.put(name, value);
}
}
}
return map;
}
输出：

这里的问题是，由于存在重复元素节点，我当前的实现仅捕获元素节点的1次出现。因此，如果有一种方法可以将密钥设为XPath，那么我可以将上述次数指示为[1]或[2]，我不会遇到这个问题。这样我就可以捕获所有的价值观。
非常感谢任何帮助或帮助。
