(AutoIt) XML Exclusive CanonicalizationDemonstrates how to convert XML to the Exclusive XML Canonicalization form as specified in http://www.w3.org/TR/xml-exc-c14n/
; 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 exclusive XML canonicalization. ; This example will show many sample XML inputs and outputs. The input XML files are available online ; as shown in this example. $oHttp = ObjCreate("Chilkat.Http") $oSbXml = ObjCreate("Chilkat.StringBuilder") $oCanon = ObjCreate("Chilkat.XmlDSig") ; Use exclusive XML canonicalization. Local $sCanonVersion = "EXCL_C14N" Local $bWithComments = False Local $sDiv1 = "--------------- input ---------------" Local $sDiv2 = "--------------- canonicalized output ---------------" Local $bSuccess $oSbUrl = ObjCreate("Chilkat.StringBuilder") Local $i = 1 While $i < 20 $oSbUrl.SetString("https://www.chilkatsoft.com/exampleData/c14n/testTESTNUMBER.xml") Local $iNumReplaced = $oSbUrl.ReplaceI("TESTNUMBER",$i) $bSuccess = $oHttp.QuickGetSb($oSbUrl.GetAsString(),$oSbXml) If ($bSuccess = True) Then Local $sXmlCanon = $oCanon.CanonicalizeXml($oSbXml.GetAsString(),$sCanonVersion,$bWithComments) ConsoleWrite("---- Test " & $i & " ----" & @CRLF) ConsoleWrite($sDiv1 & @CRLF) ConsoleWrite($oSbXml.GetAsString() & @CRLF) ConsoleWrite($sDiv2 & @CRLF) ConsoleWrite($sXmlCanon & @CRLF) ConsoleWrite(" " & @CRLF) EndIf $i = $i + 1 Wend ; The output of this program is: ; ; ---- Test 1 ---- ; --------------- input --------------- ; <?xml version="1.0"?> ; ; <?xml-stylesheet href="doc.xsl" ; type="text/xsl" ?> ; ; <!DOCTYPE doc SYSTEM "doc.dtd"> ; ; <doc>Hello, world!<!-- Comment 1 --></doc> ; ; <?pi-without-data ?> ; ; <!-- Comment 2 --> ; ; <!-- Comment 3 --> ; --------------- canonicalized output --------------- ; <?xml-stylesheet href="doc.xsl" ; type="text/xsl" ?> ; <doc>Hello, world!</doc> ; <?pi-without-data?> ; ; ---- Test 2 ---- ; --------------- input --------------- ; <?xml version="1.0"?> ; ; <?xml-stylesheet href="doc.xsl" ; type="text/xsl" ?> ; ; <doc>Hello, world!<fish name="goldie" type = "goldfish" color='gold' /></doc> ; ; <?pi-without-data ?> ; ; ; --------------- canonicalized output --------------- ; <?xml-stylesheet href="doc.xsl" ; type="text/xsl" ?> ; <doc>Hello, world!<fish color="gold" name="goldie" type="goldfish"></fish></doc> ; <?pi-without-data?> ; ; ---- Test 3 ---- ; --------------- input --------------- ; <doc> ; <clean> </clean> ; <dirty> A B </dirty> ; <mixed> ; A ; <clean> </clean> ; B ; <dirty> A B </dirty> ; C ; </mixed> ; </doc> ; --------------- canonicalized output --------------- ; <doc> ; <clean> </clean> ; <dirty> A B </dirty> ; <mixed> ; A ; <clean> </clean> ; B ; <dirty> A B </dirty> ; C ; </mixed> ; </doc> ; ; ---- Test 4 ---- ; --------------- input --------------- ; <!DOCTYPE doc [ ; <!ATTLIST normId id ID #IMPLIED> ; <!ATTLIST normNames attr NMTOKENS #IMPLIED> ; ]> ; <doc> ; <text>First line
