XML Inclusive Canonicalization

Demonstrates how to convert XML to the Inclusive XML Canonicalization form as specified in http://www.w3.org/TR/xml-c14n/ AutoIt

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

;  The XML digital signature verification class provides utility methods for
;  XML canonicalization.  This example demonstrates how to do inclusive XML canonicalization.

$oHttp = ObjCreate("Chilkat.Http")
$oSbXml = ObjCreate("Chilkat.StringBuilder")
$oCanon = ObjCreate("Chilkat.XmlDSig")

;  Use inclusive XML canonicalization.
Local $sCanonVersion = "C14N"
Local $bWithComments = False

Local $sUrl = "https://www.chilkatsoft.com/exampleData/c14n/test7.xml"
$bSuccess = $oHttp.QuickGetSb($sUrl,$oSbXml)

;  This is the input XML:
;  The XML comment is referring to when exclusive XML canonicalization is applied.  With inclusive canonicalization, the namespace nodes
;  are kept, as we'll see below..

;  <doc>
;  <!-- A namespace node N is ignored if the nearest ancestor element of the node's parent element that is in the node-set has a namespace node in the node-set with the same local name and value as N. -->
;  	<animal xmlns:aa="https://www.animal.com/">
;  		<reptile xmlns:bb="https://www.reptile.com/">
;    			<lizard xmlns="" type="african fat tailed" abc="xyz" xmlns:aa="https://www.animal.com/" />
;    			<snake type="poisonous rattler" xmlns:bb="https://www.reptile.com/" >
;    			</snake>
;    		</reptile>
;    	</animal>
;  </doc>

Local $sXmlInclCanon = $oCanon.CanonicalizeXml($oSbXml.GetAsString(),$sCanonVersion,$bWithComments)
ConsoleWrite($sXmlInclCanon & @CRLF)

;  The C14N (inclusive) canonicalization is:

;  <doc>
;  
;  	<animal xmlns:aa="https://www.animal.com/">
;  		<reptile xmlns:bb="https://www.reptile.com/">
;    			<lizard abc="xyz" type="african fat tailed"></lizard>
;    			<snake type="poisonous rattler">
;    			</snake>
;    		</reptile>
;    	</animal>
;  </doc>

;  To see the difference, let's do exclusive canonicalization..
$sCanonVersion = "EXCL_C14N"

Local $sXmlExclCanon = $oCanon.CanonicalizeXml($oSbXml.GetAsString(),$sCanonVersion,$bWithComments)
ConsoleWrite($sXmlExclCanon & @CRLF)

;  // The C14N (exclusive) canonicalization is:
;  
;  <doc>
;  
;  	<animal>
;  		<reptile>
;    			<lizard abc="xyz" type="african fat tailed"></lizard>
;    			<snake type="poisonous rattler">
;    			</snake>
;    		</reptile>
;    	</animal>
