很简单.我的代码解析了所有内容(标题,链接,描述,pubDate等),没有任何问题.但是,我得到了null:

我正在使用Java来解析RSS提要.我是否必须以不同于更简单的本地名称的方式处理复合本地名称？

这是解析Link,Description,pubDate等的一些代码:

@Override
    public void endElement(String uri, String localName, String name)
            throws SAXException {
        super.endElement(uri, localName, name);
        if (this.currentMessage != null){
            if (localName.equalsIgnoreCase(TITLE)){
                currentMessage.setTitle(builder.toString());
            } else if (localName.equalsIgnoreCase(LINK)){
                currentMessage.setLink(builder.toString());
            } else if (localName.equalsIgnoreCase(DESCRIPTION)){
                currentMessage.setDescription(builder.toString());
            } else if (localName.equalsIgnoreCase(PUB_DATE)){
                currentMessage.setDate(builder.toString());
            } else …
