Purpose
Encode an object as a character string containing XML for use with the messaging functions to pass objects between processes
Syntax
XML_ENCODE(<object> [, <expC1>, <expC2>])
See Also
Messaging Functions, MQCLOSE(), MQCREATE(), MQCURMSGS(), MQOPEN(), MQSEND(), MQRECEIVE(), MQUNLINK(), XML_DECODE(), XML_GATHER(), XML_SCATTER()
Description
The XML_ENCODE() function is used to encode an object and return a character string containing XML. The character string returned can be used with the messaging functions to pass objects between processes. The <object> is the object to be encoded. The optional character expression <expC1> is the XML root tag name. The optional character expression <expC2> is the XML row tag name.
The XML_DECODE() function is used to return the passed XML character string decoded back into an object.
Example
// Open up the queue for read/write access mqdes=mqcreate("/myqueue2", 2) if (mqdes < 0) messagebox(strerror()+",errno="+alltrim(str(error()))) return endif // send a message to the queue rc = mqsend(mqdes, xml_encode(tran_obj)) if (rc < 0) messagebox(strerror()+",errno="+alltrim(str(error()))) return endif mqclose(mqdes)
