Demonstrate the XML "I" Property

See more XML Examples

Demonstrates the XML "I" property. The properties I, J, and K can be used in paths to access the I'th, J'th, or K'th child in a path. Three indexing properties are provided to allow for triple-nested loops using this feature.

Note: This example requires Chilkat v9.5.0.64 or later.

import 'package:chilkat/chilkat.dart';

void main() {
  // This example uses the XML document at https://www.chilkatsoft.com/exampleData/xero_accounts.xml
  // The data is a download of the Xero accounts for the sandbox company test data (it's not real data).

  // We'll use Chilkat HTTP to download the XML.
  // This example assumes the Chilkat HTTP API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  final sbXml = CkStringBuilder();

  // Download the XML from https://www.chilkatsoft.com/exampleData/xero_accounts.xml
  // into sbXml
  final url = 'https://www.chilkatsoft.com/exampleData/xero_accounts.xml';

  try {
    http.quickGetSb(url, sbXml);

  final bAutoTrim = false;

  xml.loadSb(sbXml, bAutoTrim);

  // How many accounts exist?
  final numAccounts = xml.numChildrenAt('Accounts');
