(CkPython) XML Exclusive CanonicalizationDemonstrates how to convert XML to the Exclusive XML Canonicalization form as specified in http://www.w3.org/TR/xml-exc-c14n/
import chilkat # 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. http = chilkat.CkHttp() sbXml = chilkat.CkStringBuilder() canon = chilkat.CkXmlDSig() # Use exclusive XML canonicalization. canonVersion = "EXCL_C14N" withComments = False div1 = "--------------- input ---------------" div2 = "--------------- canonicalized output ---------------" sbUrl = chilkat.CkStringBuilder() i = 1 while i < 20 : sbUrl.SetString("https://www.chilkatsoft.com/exampleData/c14n/testTESTNUMBER.xml") numReplaced = sbUrl.ReplaceI("TESTNUMBER",i) success = http.QuickGetSb(sbUrl.getAsString(),sbXml) if (success == True): xmlCanon = canon.canonicalizeXml(sbXml.getAsString(),canonVersion,withComments) print("---- Test " + str(i) + " ----") print(div1) print(sbXml.getAsString()) print(div2) print(xmlCanon) print(" ") i = i + 1 # 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
