#include <C_CkXml.h>

void ChilkatSample(void)
    {
    HCkXml xml;

    xml = CkXml_Create();

    CkXml_LoadXml(xml,"<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".
    CkXml_UpdateAttribute(xml,"b","pear");

    //  Because no attribute named "c" exists, UpdateAttribute
    //  will create it:
    CkXml_UpdateAttribute(xml,"c","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.
    CkXml_AddToAttribute(xml,"a",7);

    //  Examine the result:
    printf("%s\n",CkXml_getXml(xml));

    CkXml_Dispose(xml);
