    HCkXmlW xml;
    BOOL success;

    xml = CkXmlW_Create();

    success = CkXmlW_LoadXml(xml,L"<abc a=\"123\" b=\"apple\">Test</abc>");

    // The UpdateAttribute and AddOrUpdateAttribute methods
    // are identical.  Both will replace the attribute's value if it
    // already exists, or insert a new attribute if it does not yet exist.

    // Change the value of attribute "b" to "pear".
    success = CkXmlW_UpdateAttribute(xml,L"b",L"pear");

    // Because no attribute named "c" exists, UpdateAttribute
    // will create it:
    success = CkXmlW_UpdateAttribute(xml,L"c",L"orange");

    // If an attribute's value is an integer, the AddToAttribute
    // method may be called to update it by adding an integer value.
    // For example, update the value of "a" to "130" by adding 7.
    CkXmlW_AddToAttribute(xml,L"a",7);

    // Examine the result:
    wprintf(L"%s\n",CkXmlW_getXml(xml));


    CkXmlW_Dispose(xml);
