Description

The XML_ENCODE() function is used to encode an object as a character string containing XML for use with the messaging functions to pass objects between processes. The XML_DECODE() function returns the received XML character string, <expC1>, decoded back into an object. The optional character expression <expC1> is the XML root tag name. The optional character expression <expC2> is the XML row tag name.

Example

// Proccess the message queue
do while .t.
   // Check for new messages
   do while (mqcurmsgs(m_mqdes) > 0)
       // retrieve message
       m_message = mqreceive(m_mqdes)
           // decode the XML message into an object/dynamic array
           m_objmessage = xml_decode(m_message)
           // process the message
       mq_process_message(m_objmessage, m_message)
