XML parsing not working on android build of lwuit app

问题

I use Kxml2 parser to parse the xml response I get as a response from a remote page. It is for user authentication, and the returned xml gives several details about the user. The app is built with LWUIT 1.5 and it works on MIDP and Blackberry versions. On the Android version it doesn't work. Is there any extra specification I am supposed to add, for Android to work properly?

回答1:

There is a XMLParser in LWUIT, is very easy to use. You can try to use it. It works fine in my MIDP and BB apps. I can't test it in Android but I think It could be the solution. How do you port your LWUIT apps to Android?

Well I will try to explain the use of this Parser the best that I can

You need to import this packages:

import com.sun.lwuit.xml.Element;
import com.sun.lwuit.xml.XMLParser;

In my project I extract a XML from an HTTPConnection.

Suppose out XML is as follows:

  <?xml version="1.0" encoding="UTF-8"?>
    <xml>
     <TagFromXML>
       <child>
         <data>HI</data>
       </child>
     </TagFromXML>
    <TagFromXML>
      <child>
         <data>HI2</data>
       </child>
     </TagFromXML>
    </xml>

Then do the following:

InputStream is = hc.openInputStream();
InputStreamReader isr = new InputStreamReader(is, "utf-8");
XMLParser myParser = new XMLParser();
Element e = myParser.parse(isr);
Vector tagVector = e.getChildrenByTagName("TagFromXML");
for(int i = 0; i<tagVector.size();i++){
 Element singleTag = (Element) tagVector.elementAt(i);
 Element child = (Element) (singleTag.getChildrenByTagName("child")).elementAt(0);
 Element data = (Element) (child.getChildrenByTagName("data")).elementAt(0);
 System.out.println("DATA: " + data.getChildAt(0).getText());
}

You will get
