我实际上是使用xmlpullparser来解决这个问题 - 这里只是获取图像属性“大”的代码并忽略其余部分 - 它是case语句中的最后一个“if”。

公共类XmlPullFeedParser扩展BaseFeedParser {

public XmlPullFeedParser(String feedUrl) {

super(feedUrl);

}

public ArrayList parse() {

ArrayList messages = null;

XmlPullParser parser = Xml.newPullParser();

try {

// auto-detect the encoding from the stream

parser.setInput(this.getInputStream(), null);

int eventType = parser.getEventType();

Message currentMessage = null;

boolean done = false;

while (eventType != XmlPullParser.END_DOCUMENT && !done){

String name = null;

String attrib = null;

switch (eventType){

break;
