* This example assumes the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.

lnSuccess = 1

* First create the XML to be signed, or load it from a file, or a string,

* To load XML from a file:
loXmlToSign = CreateObject('Chilkat.Xml')
lnSuccess = loXmlToSign.LoadXmlFile("c:/someDir/mx_document.xml")

* Or to load XML from a string
lnSuccess = loXmlToSign.LoadXml("...")

* Or create the XML directly.
loXmlToSign.Clear()
