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:

bool success = false;
CkXml xml;
success = xml.LoadXmlFile("qa_data/xml/pigs.xml");

// Get the content of the "species" node for the 1st animal:
const char *result = 0;
result = xml.chilkatPath("animal|species|*");
// Output should be "pot belly pig"
std::cout << result << "\r\n";
// Get the content of the "type" node for the 2nd animal:
// Indexing begins at 0. Therefore, the 2nd direct child having
// the tag "animal" is at index 1
result = xml.chilkatPath("animal[1]|type|*");
// Output should be "House Pig"
std::cout << result << "\r\n";
// Find the pig having the name "Nigel" and display the
// birth date. To do this, we'll navigate to the node having
// tag="name" with the exact content "Nigel", then navigate up,
// and finally navigate back down to the "birth" node:
result = xml.chilkatPath("/C/name,Nigel|..|birth|*");
// Output should be "June, 1991"
std::cout << result << "\r\n";
// Navigate to the 1st animal's picture and print the filename,
// description, and caption.
// The "$" updates the caller's internal pointer to reference
// the node that is the result of evaluating the path.
// An empty string is returned for success, and a NULL/nil/0
// pointer (reference) is returned on failure.
result = xml.chilkatPath("animal|picture|$");
if (xml.get_LastMethodSuccess() != true) {
std::cout << "Failed to navigate to animal|picture." << "\r\n";
return;
}
// Display the contents of the file/description/caption child nodes
std::cout << "Picture Info:" << "\r\n";
std::cout << xml.getChildContent("file") << "\r\n";
std::cout << xml.getChildContent("description") << "\r\n";
std::cout << xml.getChildContent("caption") << "\r\n";
// Return back to the root of the XML document:
xml.GetRoot2();
// Display the value of the "spay-neuter" attribute of the 1st animal:
std::cout << "----" << "\r\n";
