Question

我正在尝试解析一个我不知道结构的XML文档。有人建议使用XPath，但我没有运气试图让它工作。

实施例：我需要的是（来自XML文档）：

Return/ReturnData/IRS1095A{a77f40a2-af31-4404-a27d-4c1eaad730c2}/MonthlyPTCInfo‌rmationGrpPP{69dc9dd5-5415-4ee4-a199-19b2dbb701be}/MonthlyPlanPremiumAmtPP=136

回调方法应记住每个阶段的START_ELEMENT层次结构。使用堆栈记住名称并构造一个xpath。拥有键值对

代码：

public Map<String, String> p(File file) throws Exception {

    Map<String, String> map = new HashMap<String,String>();
    XMLStreamReader xr = XMLInputFactory.newInstance().createXMLStreamReader(new FileInputStream(file));

    String name = "", value = "", attrName = "";

    while(xr.hasNext()) {
        int e = xr.next();

        switch(e) {
            case XMLStreamReader.START_ELEMENT: {
                name = xr.getLocalName();
                final int attributeCount = xr.getAttributeCount();

                if(attributeCount > 0) {
                    attrName = xr.getAttributeName(0).getLocalPart();
                    final String attributeValue = xr.getAttributeValue(0);
                        logger.debug("Key: "+name+" AttributeName: "+attrName+" Attribute value: "+attributeValue);
                }
                break;
            }

            case XMLStreamReader.CHARACTERS:
                value = xr.getText();
                break;
        }

        Map<String, String> map = new HashMap<String,String>();
        map.put(name, value);

        logger.debug("This is Map: "+map);
    }
    return null;//map;
}
