这是我尝试使用 XmlPullParser 在 Android Java 中读取的 XML，但我找不到读取 <link/> 标记的方法，因为它是自封闭标记

这是我的 java 代码 sn-p 试图通过 xml 归档读取

while (eventType != XmlPullParser.END_DOCUMENT) {
    if (eventType == XmlPullParser.START_TAG) {
        if (xpp.getName().equalsIgnoreCase("entry")) {
            insideItem = true;
        } else if (xpp.getName().equalsIgnoreCase("title")) {
            if (insideItem) {
                titles.add(xpp.nextText());
            }
        } else if (xpp.getName().equalsIgnoreCase("link")) {
            if (insideItem) {
                links.add(xpp.nextText());
            }
        } else if (xpp.getName().equalsIgnoreCase("content")) {
            if (insideItem) {
                content.add(xpp.nextText());
            }
        } else if (xpp.getName().equalsIgnoreCase("published")) {
            if (insideItem) {
                published.add(xpp.nextText());
            }
        }
    } else if (eventType == XmlPullParser.END_TAG && 
               xpp.getName().equalsIgnoreCase("entry")) {

               insideItem = false;
    }

    eventType = xpp.next();
}

【解决方案1】：

我终于可以使用这段代码读取自闭标签了：

protected Exception doInBackground(Integer... integers) {
            try {

                url = new URL(RSS_URL_2);

                XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
                factory.setNamespaceAware(false);

                XmlPullParser xpp = factory.newPullParser();

                xpp.setInput(getInputStream(url), "UTF_8");

                boolean insideItem = false;

                int eventType = xpp.getEventType();

                while (eventType != XmlPullParser.END_DOCUMENT) {
                    if (eventType == XmlPullParser.START_TAG) {
                        if (xpp.getName().equalsIgnoreCase("entry")) {
                            insideItem = true;
                        } else if (xpp.getName().equalsIgnoreCase("title")) {
                            if (insideItem) {
                                titles.add(xpp.nextText());
                            }
                        } else if (xpp.getName().equals("link")) {
                            if (insideItem) {
                                links.add(xpp.getAttributeValue(null, "href"));
                            }
                        } else if (xpp.getName().equalsIgnoreCase("content")) {
                            if (insideItem) {
                                content.add(xpp.nextText());
                            }
                        } else if (xpp.getName().equalsIgnoreCase("published")) {
                            if (insideItem) {
                                published.add(xpp.nextText());
                            }
                        }
                    } else if (eventType == XmlPullParser.END_TAG && xpp.getName().equalsIgnoreCase("entry")) {
                        insideItem = false;
                    }

                    eventType = xpp.next();
                }

            } catch (MalformedURLException me) {
                exception = me;
            } catch (XmlPullParserException xp) {
                exception = xp;
            } catch (IOException ie) {
                exception = ie;
            }

            return exception;
        }
