Parameters Required Default Description
<XML filename> Yes None The name of the XML file to read.
<memvar1> Yes None The name of a memory variable that will return the XML target table name. Ignored if XMLFORMAT is ADO.
<memvar2> Yes None The name of a memory variable that will return the transaction type for the record. Valid types are INSERT, UPDATE and DELETE. Ignored if XMLFORMAT is ADO.

The XMLFIRST() function will return -1 if it fails, as some transaction type can contain zero fields. The XML file format is set to ADO (Microsoft® ActiveX® Data Objects XML Format) by default. The SET XMLFORMAT command can be used to toggle the XML file format between ADO and Recital.


Example

number = xmlfirst("sales.xml", target, trans, where, names, data)
