我在RSS提要解析中是全新的。我正在嘗試的是獲取mp3文件的持續時間。但我無法從一個特定的標籤RSS提要解析，提取字段值
<itunes:duration>01:00:00</itunes:duration>
這裏獲得價值是我的解析代碼：
public List<RSSItem> parse() {
final RSSItem currentMessage = new RSSItem();
RootElement root = new RootElement("rss");
final List<RSSItem> messages = new ArrayList<RSSItem>();
Element channel = root.getChild("channel");
Element item = channel.getChild(ITEM);
item.setEndElementListener(new EndElementListener() {
public void end() {
messages.add(currentMessage.copy());
}
});
item.getChild(TITLE).setEndTextElementListener(
new EndTextElementListener() {
public void end(String body) {
currentMessage.setTitle(body);
}
});
item.getChild(LINK).setEndTextElementListener(
new EndTextElementListener() {
public void end(String body) {
currentMessage.setLink(body);
}
});
item.getChild(DESCRIPTION).setEndTextElementListener(
new EndTextElementListener() {
public void end(String body) {
currentMessage.setDescription(body);
}
});
item.getChild("http://purl.org/rss/1.0/modules/content/", "encoded")
.setEndTextElementListener(new EndTextElementListener() {
public void end(String body) {
currentMessage.setContent(body);
}
});
item.getChild(CONTENT).setEndTextElementListener(
new EndTextElementListener() {
public void end(String body) {
currentMessage.setContent(body);
}
});
item.getChild(PUB_DATE).setEndTextElementListener(
new EndTextElementListener() {
public void end(String body) {
currentMessage.setDate(body);
}
});
item.getChild(CATEGORY).setEndTextElementListener(
new EndTextElementListener() {
public void end(String body) {
currentMessage.setCategory(body);
}
});
Element enclosure = item.getChild(ENCLOSURE);
enclosure.setStartElementListener(new StartElementListener() {
public void start(Attributes attributes) {
currentMessage.setAdioUrl(attributes.getValue("url"));
// currentMessage.setAdioFileDuration(attributes.getValue("length"));
}
});
item.getChild(ADIOFILEDuration).setEndTextElementListener(
new EndTextElementListener() {
public void end(String body) {
currentMessage.setAdioFileDuration(body);
}
}); //ADIOFILEDuration=itunes
try {
Xml.parse(this.getInputStream(), Xml.Encoding.UTF_8,
root.getContentHandler());
} catch (Exception e) {
throw new RuntimeException(e);
}
return messages;
}
這裏是RSS對象：
