(Lianja) Demonstrate the XML I, J, and K PropertiesDemonstrates the XML I, J, and K properties. These properties 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.
