如何从 guid 中获取此 isPermaLink=“false” 文本？

问：

如何从guid中获取此文本isPermaLink=“false”？

<guid isPermaLink="false">article-67228311</guid>

我正在使用这个库com.rometools.rome.feed.synd.SyndEntry。有没有办法使用此库在 guid 标记中获取值？下面的 print 语句将值打印为 article-67228311，但我想获取 isPermaLink=“false” 文本。

示例代码：

try (CloseableHttpClient client = HttpClients.createMinimal()) {
    HttpUriRequest request = new HttpGet(feedUrl);
    try (CloseableHttpResponse response = client.execute(request); InputStream stream = response.getEntity().getContent()) {
        SyndFeedInput input = new SyndFeedInput();
        SyndFeed feed = input.build(new XmlReader(stream));
        Iterator iter = feed.getEntries().iterator();
        while (iter.hasNext()) {
            SyndEntry syndEntry = (SyndEntry) iter.next();
            System.out.println("guid ========" + syndEntry.getUri());
        }
    }
}
