(C++) Demonstrates the ChilkatPath XML MethodDemonstrates how to use the ChilkatPath method. This example uses the XML sample file pigs.xml. The pigs.xml file contains this content:
#include <CkXml.h> void ChilkatSample(void) { CkXml xml; bool success = xml.LoadXmlFile("qa_data/xml/pigs.xml"); if (success != true) { std::cout << xml.lastErrorText() << "\r\n"; return; } // 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"; result = xml.chilkatPath("animal|gender|(spay-neuter)"); std::cout << result << "\r\n"; } |
