但它返回:

我想,应该添加namespace()来修复它,但我不知道怎么做。我可能做得不对,但它可以(!):
publicstaticvoidmain(字符串[]args)引发异常{
URL feedUrl=新URL(“https://stackoverflow.com/jobs/feed");
SyndFeedInput=新的SyndFeedInput();
SyndFeed feed=input.build(新的XmlReader(feedUrl));
feed.getEntries()
.forEach(条目->{
System.out.println(get(“author”,entry.getForeignMarkup());
System.out.println(get(“updated”,entry.getForeignMarkup());
});
}
私有静态字符串get(字符串名称,列表foreignMarkup){
返回foreignMarkup.stream()
.filter(e->name.equals(e.getName()))
.map(元素::getValue)
.findFirst()
.orElse(空);
}
本质上:在每个SyncEntry
上调用getForeignMarkup()
,然后在返回的列表中查找名称与“author”、“updated”等匹配的元素。我可能用错误的方法执行此操作,但它可以(!):
