XML Parsing (Android parse XML file from Assets folder)

1.Sample Order XML file - order.xml

<?xml version="1.0" encoding="utf-8" ?>

<PurchaseOrder>

  <OrderId>5</OrderId>

  <CustomerId>0275125</CustomerId>

  <Email>prashantkoli71@gmail.com</Email>

  <OrderItemDetail>

    <LineNumber>1</LineNumber>

    <ProductSku>12010109Y</ProductSku>

    <Quantity>2.00</Quantity>

    <Price>7.99</Price>

   </OrderItemDetail>

  <OrderItemDetail>

    <LineNumber>2</LineNumber>

    <ProductSku>12010109B</ProductSku>

    <Quantity>900</Quantity>

    <Price>83.50</Price>

   </OrderItemDetail>

  <OrderItemDetail>

    <LineNumber>3</LineNumber>

    <ProductSku>11271581Y</ProductSku>

    <Quantity>16.00</Quantity>

    <Price>8.99</Price>

   </OrderItemDetail>

</PurchaseOrder>

2.Android Application main Layout - main.xml

<?xml version="1.0" encoding="UTF-8"?>

<RelativeLayout 

  xmlns:android="http://schemas.android.com/apk/res/android"

 xmlns:tools="http://schemas.android.com/tools"   

  android:layout_width="match_parent"

 android:layout_height="match_parent">

 <TextView  

  android:id="@+id/textView1"  

  android:layout_width="wrap_content"

  android:layout_height="wrap_content" 

   android:layout_alignParentLeft="true"

  android:layout_alignParentTop="true"  

  android:layout_marginTop="14dp"

  android:text="@string/parsed_data"    

  android:textAppearance="?android:attr/textAppearanceMedium"

  android:textStyle="bold" />

 <ScrollView  

  android:id="@+id/scrollView1"

  android:layout_width="wrap_content" 

  android:layout_height="wrap_content"

  android:layout_alignParentLeft="true" 

   android:layout_below="@+id/textView1"

  android:layout_marginTop="10dp">

  <LinearLayout

      android:id="@+id/linearLayout1"

      android:layout_width="match_parent"

      android:layout_height="wrap_content"

      android:orientation="vertical" />

 </ScrollView>

</RelativeLayout>

 3.Shopping Cart Java Object - ProductInfo.java

package com.prashant.xml;

public class ProductInfo {

  

 String seqNo = null;

 String itemNumber = "";

 String quantity = "";

 String price = "";

  

 public String getSeqNo() {

  return seqNo;

 }

 public void setSeqNo(String seqNo) {

  this.seqNo = seqNo;

 }

 public String getItemNumber() {

  return itemNumber;

 }

 public void setItemNumber(String itemNumber) {

  this.itemNumber = itemNumber;

 }

 public String getQuantity() {

  return quantity;

 }

 public void setQuantity(String quantity) {

  this.quantity = quantity;

 }

 public String getPrice() {

  return price;

 }

 public void setPrice(String price) {

  this.price = price;

 }

}

4.Custom XML handler for parsing - OrderXMLHandler.java

package com.prashant.xml;

import java.util.ArrayList;

import org.xml.sax.Attributes;

import org.xml.sax.SAXException;

import org.xml.sax.helpers.DefaultHandler;

public class OrderXMLHandler extends DefaultHandler {

 boolean currentElement = false;

 String currentValue = "";

 String cartId;

 String customerId;

 String email;

 ProductInfo productInfo;

 ArrayList<ProductInfo> cartList;

  

 public String getCartId() {

  return cartId;

 }

 public String getCustomerId() {

  return customerId;

 }

  

 public String getEmail() {

  return email;

 }

 public ArrayList<ProductInfo> getCartList() {

  return cartList;

 }

  

 public void startElement(String uri, String localName, String qName,

   Attributes attributes) throws SAXException {

  currentElement = true;

  if (qName.equals("PurchaseOrder")){

   cartList = new ArrayList<ProductInfo>();

  }

  else if (qName.equals("OrderItemDetail")) {

   productInfo = new ProductInfo();

  }

 }

 public void endElement(String uri, String localName, String qName)

 throws SAXException {

  currentElement = false;

  if (qName.equalsIgnoreCase("OrderId"))

   cartId = currentValue.trim();

  else if (qName.equalsIgnoreCase("CustomerId"))

   customerId = currentValue.trim();

  else if (qName.equalsIgnoreCase("Email"))

   email = currentValue.trim();

  else if (qName.equalsIgnoreCase("LineNumber"))

   productInfo.setSeqNo(currentValue.trim());

  else if (qName.equalsIgnoreCase("ProductSku"))

   productInfo.setItemNumber(currentValue.trim());

  else if (qName.equalsIgnoreCase("Quantity"))

   productInfo.setQuantity(currentValue.trim());

  else if (qName.equalsIgnoreCase("Price"))

   productInfo.setPrice(currentValue.trim());

  else if (qName.equalsIgnoreCase("OrderItemDetail"))

   cartList.add(productInfo);

  currentValue = "";

 }

 public void characters(char[] ch, int start, int length)

 throws SAXException {

  if (currentElement) {

   currentValue = currentValue + new String(ch, start, length);

  }

 }

}

5.Android Application main Activity - MainActivity.java

package com.prashant.xml;

import java.io.InputStream;

import java.util.ArrayList;

import javax.xml.parsers.SAXParser;

import javax.xml.parsers.SAXParserFactory;

import org.xml.sax.InputSource;

import org.xml.sax.XMLReader;

import android.os.Bundle;

import android.app.Activity;

import android.content.res.AssetManager;

import android.util.Log;

import android.view.Menu;

import android.widget.LinearLayout;

import android.widget.TextView;

public class MainActivity extends Activity {

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        parseXML();

    }

    private void parseXML() {

        AssetManager assetManager = getBaseContext().getAssets();

        try {

            InputStream is = assetManager.open("order.xml");

            SAXParserFactory spf = SAXParserFactory.newInstance();

   SAXParser sp = spf.newSAXParser();

   XMLReader xr = sp.getXMLReader();

   OrderXMLHandler myXMLHandler = new OrderXMLHandler();

   xr.setContentHandler(myXMLHandler);

   InputSource inStream = new InputSource(is);

   xr.parse(inStream);

    

   String cartId = myXMLHandler.getCartId();

   String customerId = myXMLHandler.getCustomerId();

   String email = myXMLHandler.getEmail();

    

   Log.v("abc", cartId);

   LinearLayout ll = (LinearLayout)findViewById(R.id.linearLayout1);

   TextView tv = new TextView(this);

         tv.setText("Cart Id: " + cartId);

         ll.addView(tv);

         tv = new TextView(this);

         tv.setText("Customer Id: " + customerId);

         ll.addView(tv);

         tv = new TextView(this);

         tv.setText("Email : " + email);

         ll.addView(tv);

         tv = new TextView(this);

         tv.setText("Shopping Cart Info --->");

         ll.addView(tv);

          

   ArrayList<ProductInfo> cartList = myXMLHandler.getCartList();

   for(ProductInfo productInfo: cartList){

    tv = new TextView(this);

          tv.setText("Line No : " + productInfo.getSeqNo());

          ll.addView(tv);

          tv = new TextView(this);

          tv.setText("Item No : " + productInfo.getItemNumber());

          ll.addView(tv);

          tv = new TextView(this);

          tv.setText("Quantity : " + productInfo.getQuantity());

          ll.addView(tv);

          tv = new TextView(this);

          tv.setText("Price : " + productInfo.getPrice());

          ll.addView(tv);

          tv = new TextView(this);

          tv.setText("---");

          ll.addView(tv);

   }

            is.close();

             

        } catch (Exception e) {

            e.printStackTrace();

        }

    }
