Demonstrate the XML FindNextRecord Method

See more XML Examples

Imagine we have an XML file as follows:

<CompleteMultipartUpload>
  <Part>
    <PartNumber>1</PartNumber>
    <ETag>abc</ETag>
  </Part>
  <Part>
    <PartNumber>2</PartNumber>
    <ETag>def</ETag>
  </Part>
  <Part>
    <PartNumber>3</PartNumber>
    <ETag>ghi</ETag>
  </Part>
</CompleteMultipartUpload>

We want to find the record where PartNumber = 2. To do so, we simply position ourselves at the first "Part" tag, and then call FindNextRecord. (See below..) Android™

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.
package com.test;

import android.app.Activity;
import com.chilkatsoft.*;

import android.widget.TextView;
import android.os.Bundle;

public class SimpleActivity extends Activity {

  private static final String TAG = "Chilkat";

  // Called when the activity is first created.
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    CkXml xml = new CkXml();

    xml.LoadXmlFile("qa_data/xml/multipartUpload.xml");

    // Position ourselves at the 1st record.
    xml.GetChild2(0);

    CkXml foundRec = xml.FindNextRecord("PartNumber","2");
    if (xml.get_LastMethodSuccess() == true) {
        Log.i(TAG, "Found the record where PartNumber = 2.");
        Log.i(TAG, foundRec.getXml());

        // Let's examine the ETag for this record...
        Log.i(TAG, "ETag for PartNumber 2 = " + foundRec.getChildContent("ETag"));

        }
    else {
        Log.i(TAG, "No record exists where PartNumber = 2.");
        }

    // What if we want to find the record where ETag = "abc"?
    foundRec = xml.FindNextRecord("ETag","abc");
    if (xml.get_LastMethodSuccess() == true) {
        Log.i(TAG, "Found the record where ETag = abc");
        Log.i(TAG, foundRec.getXml());

        // Let's examine the PartNumber for this record...
        Log.i(TAG, "Part number for Etag(abc) = " + foundRec.getChildContent("PartNumber"));

        }
    else {
        Log.i(TAG, "No record exists where ETag = abc.");
        }

    // Go back to the XML root..
    xml.GetRoot2();

  }

  static {
      System.loadLibrary("chilkat");

      // Note: If the incorrect library name is passed to System.loadLibrary,
      // then you will see the following error message at application startup:
      //"The application <your-application-name> has stopped unexpectedly. Please try again."
