XML to XSD , XSD Generator

XSD Generation:

If you have sample XML File with test data then generate the XSD automatically with some tools which was provided by MICROSOFT.

Please download the xsd.exe file or you can download from here xsd.exe; (Google for xsd.exe )

How to  use this tool:

The XML Schema Definition (Xsd.exe) tool generates XML schema or common language runtime classes from XDR, XML, and XSD files, or from classes in a runtime assembly.

xsd file.xdr [/outputdir:directory][/parameters:file.xml]

xsd file.xml [/outputdir:directory] [/parameters:file.xml]

xsd file.xsd {/classes | /dataset} [/element:element]
             [/enableLinqDataSet] [/language:language]
                          [/namespace:namespace] [/outputdir:directory] [URI:uri]
                          [/parameters:file.xml]

xsd {file.dll | file.exe} [/outputdir:directory] [/type:typename [...]][/parameters:file.xml]

How to change datatype  in xsd :

2. Open in design mode .

Android XML Parsing

I have a requirement to read the XML content in Android project.
So googling for long time and people are talking about the JAXB versionof android and XML to POJO utilities etc...but I found that Android itself has own API to read XML content, which is beautiful.

I came across this API which I will give you the example here .
It also has the better implementations of SAX parsers inside the android .

you can go through this :
http://developer.android.com/reference/org/xmlpull/v1/XmlPullParser.html
which is from ANDROID SDK exmaples itself.

I don't know when will this be removed or updated from the site or for quick reference I am pasting here.

================

import java.io.IOException;
 import java.io.StringReader;

 import org.xmlpull.v1.XmlPullParser;
 import org.xmlpull.v1.XmlPullParserException;
 import org.xmlpull.v1.XmlPullParserFactory;

 public class SimpleXmlPullApp
 {

     public static void main (String args[])
         throws XmlPullParserException, IOException
     {
         XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
         factory.setNamespaceAware(true);
         XmlPullParser xpp = factory.newPullParser();

         xpp.setInput( new StringReader ( "<foo>Hello World!</foo>" ) );
         int eventType = xpp.getEventType();
         while (eventType != XmlPullParser.END_DOCUMENT) {
          if(eventType == XmlPullParser.START_DOCUMENT) {
              System.out.println("Start document");
          } else if(eventType == XmlPullParser.START_TAG) {
              System.out.println("Start tag "+xpp.getName());
          } else if(eventType == XmlPullParser.END_TAG) {
              System.out.println("End tag "+xpp.getName());
          } else if(eventType == XmlPullParser.TEXT) {
              System.out.println("Text "+xpp.getText());
          }
          eventType = xpp.next();
         }
         System.out.println("End document");
     }
 }
 

The above example will generate the following output:

 Start document
 Start tag foo
 Text Hello World!
 End tag foo
 End document
