XMLHTTP. Send (xmldoc)

If xml http. Status = 200 then
Xmldoc. Load (XMLHTTP. responsexml)
Response. Write XMLHTTP. Status &"

Response. Write XMLHTTP. statustext &"
The execution result is :"
Response. Write xmldoc. getelementsbytagname ("getczidresult") (0). Text
Else

Retrieve the returned value xmldoc. getelementsbytagname from the returned xmldoc
