Xml TagPath Property Explained

Demonstrates and explains the TagPath property.

Note: The TagPath property was introduced in Chilkat v9.5.0.77

C++

#include <CkXml.h>

void ChilkatSample(void)
    {
    bool success = false;

    CkXml xml;

    // Load some XML:
    success = xml.LoadXml("<a><bbb><ccc><ddd>1</ddd><ddd><z>zzz</z></ddd><ddd>3</ddd></ccc></bbb></a>");

    std::cout << xml.getXml() << "\r\n";

    // This is what we have:

    // <?xml version="1.0" encoding="utf-8"?>
    // <a>
    //     <bbb>
    //         <ccc>
    //             <ddd>1</ddd>
    //             <ddd>
    //                 <z>zzz</z>
    //             </ddd>
    //             <ddd>3</ddd>
    //         </ccc>
    //     </bbb>
    // </a>

    // The TagPath property is read-only property that returns the unique path to the
    // node from the document root.

    // For example:
    bool found = xml.SearchForTag2(xml,"z");
    if (found == true) {
        // We found a node having the tag "z".
        // The TagPath property tells us the location in the document.
        const char *tagPath = xml.tagPath();
        std::cout << tagPath << "\r\n";

        // The tagPath is bbb|ccc|ddd[1]|z

        // If we to back to the document root, we can get to the given node via the tagPath.
        xml.GetRoot2();
        std::cout << xml.tag() << "\r\n";
        // The root tag is "a".

        // Follow the tagPath to the "z" node:
        found = xml.FindChild2(tagPath);
        std::cout << "found = " << found << ", tag = " << xml.tag() << "\r\n";
        // We are now at "z".

    }
    }
