(Delphi ActiveX) Demonstrates the ChilkatPath XML Method

Demonstrates how to use the ChilkatPath method. This example uses the XML sample file pigs.xml. The pigs.xml file contains this content:

Chilkat ActiveX DLL for Delphi

Chilkat non-ActiveX DLL for Delphi

* The examples here use the ActiveX DLL.
