(Swift) XML Inclusive CanonicalizationDemonstrates how to convert XML to the Inclusive XML Canonicalization form as specified in http://www.w3.org/TR/xml-c14n/
func chilkatTest() { // 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. let http = CkoHttp()! let sbXml = CkoStringBuilder()! let canon = CkoXmlDSig()! // Use inclusive XML canonicalization. var canonVersion: String? = "C14N" var withComments: Bool = false var url: String? = "https://www.chilkatsoft.com/exampleData/c14n/test7.xml" var success: Bool = http.quickGetSb(url, sbContent: sbXml) // 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> var xmlInclCanon: String? = canon.canonicalizeXml(sbXml.getAsString(), version: canonVersion, withComments: withComments) print("\(xmlInclCanon!)") // 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.. canonVersion = "EXCL_C14N" var xmlExclCanon: String? = canon.canonicalizeXml(sbXml.getAsString(), version: canonVersion, withComments: withComments) print("\(xmlExclCanon!)") // // The C14N (exclusive) canonicalization is: // // <doc> // // <animal> // <reptile> // <lizard abc="xyz" type="african fat tailed"></lizard> // <snake type="poisonous rattler"> // </snake> // </reptile> // </animal> // </doc> } |
