问题
I'm trying to fetch image url from XML. I'm using jsoup to parse.
I am using the following code:
doc = Jsoup.connect(mainUrl).timeout(1000 * 1000).get();
final String title = doc.select("title").first().text();
final String description = doc.select("description").first()
.text().toString();
final String link = doc.select("link").first().nextSibling()
.toString();
for (Element image : doc.select("image")) {
Log.d(TAG, "inside for loop.................");
final String titleImage = image.select("title").first()
.text();
final String linkImage = image.select("link").first()
.text().toString();
final String urlImage = image.select("url").first().text()
.toString();
Log.d(TAG, "titleIm is : " + titleImage + " linkIm: "
+ linkImage + " urlIM: " + urlImage);
}
Log.d(TAG, "title is : " + title + " desc: " + description
+ " link: " + link + " url: " + url);
Control didn't come into for loop. But, <image> tag is in XML(url) only.
What mistake I did?
I couldn't find out.
Thank you in advance!!!

回答1:
If you are looking to fetch the url in enclosure tag, then this should do it
Elements items = doc.select("item");
for (Element item : items) {
String imageUrl = item.select("enclosure").first().attr("url");
}
回答2:
You can use a XMLPullParser to get the data from your rss feed.
http://developer.android.com/training/basics/network-ops/xml.html
URL url = new URL("http://feeds.hindustantimes.com/HT-IndiaSectionPage-Topstories ");
XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
factory.setNamespaceAware(false);
XmlPullParser xpp = factory.newPullParser();
xpp.setInput(url.openConnection().getInputStream(), "UTF_8");
//xpp.setInput(getInputStream(url), "UTF-8");
boolean insideItem = false;
// Returns the type of current event: START_TAG, END_TAG, etc..
int eventType = xpp.getEventType();
while (eventType != XmlPullParser.END_DOCUMENT) {
if (eventType == XmlPullParser.START_TAG) {
if (xpp.getName().equalsIgnoreCase("item")) {
insideItem = true;
} else if (xpp.getName().equalsIgnoreCase("title")) {
if (insideItem)
Log.i("hi",(xpp.nextText()));
} else if (xpp.getName().equalsIgnoreCase("link")) {
if (insideItem)
Log.i("hi",(xpp.nextText()));
}
else if (xpp.getName().equalsIgnoreCase("url")) {
if (insideItem)
{
Log.i("hi",(xpp.nextText()));
}//extract the link of article
}
}else if(eventType==XmlPullParser.END_TAG && xpp.getName().equalsIgnoreCase("item")){
insideItem=false;
}
eventType = xpp.next(); //move to next element
}
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (XmlPullParserException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
回答3:
Elements yourParsedText = doc.select(item);
for(Element media : yourParsedText) {
String mediaLinkThatYouGet = media.select("media|thumbnail")
.attr("url");
}
the base code is like that.
