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:
Unicode C

#include <C_CkXmlW.h>

void ChilkatSample(void)
    {
    BOOL success;
    HCkXmlW xml;
    const wchar_t *result;

    success = FALSE;

    xml = CkXmlW_Create();

    success = CkXmlW_LoadXmlFile(xml,L"qa_data/xml/pigs.xml");
    if (success != TRUE) {
        wprintf(L"%s\n",CkXmlW_lastErrorText(xml));
        CkXmlW_Dispose(xml);
        return;
    }

    //  Get the content of the "species" node for the 1st animal:

    result = CkXmlW_chilkatPath(xml,L"animal|species|*");
    //  Output should be "pot belly pig"
    wprintf(L"%s\n",result);

    //  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 = CkXmlW_chilkatPath(xml,L"animal[1]|type|*");
    //  Output should be "House Pig"
    wprintf(L"%s\n",result);

    //  Find the pig having the name "Nigel" and display the
    //  birth date.  To do this, we&apos;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 = CkXmlW_chilkatPath(xml,L"/C/name,Nigel|..|birth|*");
    //  Output should be "June, 1991"
    wprintf(L"%s\n",result);

    //  Navigate to the 1st animal&apos;s picture and print the filename,
    //  description, and caption.
    //  The "$" updates the caller&apos;s internal pointer to reference
    //  the node that is the result of evaluating the path.
    //  An empty string is returned for success, and a NULL/nil/0
    //  pointer (reference) is returned on failure.  
    result = CkXmlW_chilkatPath(xml,L"animal|picture|$");
    if (CkXmlW_getLastMethodSuccess(xml) != TRUE) {
        wprintf(L"Failed to navigate to animal|picture.\n");
        CkXmlW_Dispose(xml);
        return;
    }

    //  Display the contents of the file/description/caption child nodes
    wprintf(L"Picture Info:\n");
    wprintf(L"%s\n",CkXmlW_getChildContent(xml,L"file"));
    wprintf(L"%s\n",CkXmlW_getChildContent(xml,L"description"));
    wprintf(L"%s\n",CkXmlW_getChildContent(xml,L"caption"));

    //  Return back to the root of the XML document:
    CkXmlW_GetRoot2(xml);

    //  Display the value of the "spay-neuter" attribute of the 1st animal:
    wprintf(L"----\n");
    result = CkXmlW_chilkatPath(xml,L"animal|gender|(spay-neuter)");
    wprintf(L"%s\n",result);


    CkXmlW_Dispose(xml);
