在通过罗马解析RSS feed时，不允许在prolog中获取内容 [英] While parsing RSS feed through Rome getting Content is not allowed in prolog

问题描述

使用罗马API来解析RSS Feed我收到此错误：

  com.sun.syndication.io.ParsingFeedException ：com.sun.syndication.io.WireFeedInput.build中的XML 
无效（WireFeedInput.java:210）
  

代码如下：

  public static void main（String [] args）{
网址url; 
 XmlReader reader = null; 
 SyndFeed feed; 
 
 try {
 url = new URL（https://www.democracynow.org/podcast.xml）; 
 reader = new XmlReader（url）; 
 feed = new SyndFeedInput（）。build（reader）; 
 for（Iterator< SyndEntry> i = feed.getEntries（）。iterator（）; i.hasNext（）;）{
 SyndEntry entry = i.next（）; 
 System.out.println（entry.getPublishedDate（）+Title+ entry.getTitle（））; 
 
} 
} 
 catch（Exception e）{
 e.printStackTrace（）; 
} 
} 
  

我检查了一些链接， p>

问题可能来自于字符集，但我无法想出一种方法来实现。

解决方案

我也使用Syndication，我可以得到发布的日期和标题。

我的代码如下：

  URL feedUrl = new URL（http://www.bloomberg .com / tvradio / podcast / cat_markets.xml）; 
 
 SyndFeedInput input = new SyndFeedInput（）; 
 SyndFeed feed = input.build（new XmlReader（feedUrl））; 
 
 for（Iterator i = feed.getEntries（）。iterator（）; i.hasNext（）;）
 {
 SyndEntry entry =（SyndEntry）i.next ; 
 System.out.println（title |+ entry.getTitle（）+-timeStamp+ entry.getPublishedDate（）\\\
）
} 
  

这是有效的，我使用了Bloomberg Url，因为它给我一个XML。

如果您的查询是别的，请告诉我:)

Using Rome API to parse the RSS feeds I am getting this error :

com.sun.syndication.io.ParsingFeedException: Invalid XML
    at com.sun.syndication.io.WireFeedInput.build(WireFeedInput.java:210)

The code is as below:

public static void main(String[] args) {
    URL url;
    XmlReader reader = null;
    SyndFeed feed; 

    try {
        url = new URL("https://www.democracynow.org/podcast.xml");
        reader = new XmlReader(url);
        feed = new SyndFeedInput().build(reader);
        for (Iterator<SyndEntry> i =feed.getEntries().iterator(); i.hasNext();) {
            SyndEntry entry = i.next();
            System.out.println(entry.getPublishedDate()+" Title  "+entry.getTitle());

        }
    }
    catch (Exception e) {
        e.printStackTrace();
    }
}

I checked for some of the links like :

http://old.nabble.com/Invalid-XML:-Error-on-line-1:-Content-is-not-allowed-in-prolog.-td21258868.html

Where the problem is presumably is of charsets but I could not figure a way to get this implemented. Any help or guidance would be highly appreciative.

Thanks and Regards,

解决方案

I am using Syndication as well and i am able to get published date and title.

My code is as follows:

URL feedUrl = new URL("http://www.bloomberg.com/tvradio/podcast/cat_markets.xml");

SyndFeedInput input = new SyndFeedInput();
SyndFeed feed = input.build(new XmlReader(feedUrl));

for (Iterator i = feed.getEntries().iterator(); i.hasNext();)
{
SyndEntry entry = (SyndEntry) i.next();
System.out.println("title |"+entry.getTitle()+"   " -timeStamp "+entry.getPublishedDate()"\n")
}

This works , and i have used Bloomberg Url just cause it gives me a XML.

If your query was something else , do let me know :)
