USAGE

Usage, parse XML

To parse an Dsig (Signature root) XML file (using XMLReader) :

<?php
namespace Kigkonsult\DsigSdk;
use Kigkonsult\DsigSdk\XMLParse\DsigParser;

$dsig = DsigParser::factory()->parse( 
    file_get_contents( 'DsigFile.xml' )
);

$signedInfo = $dsig->getsignedInfo();
...

The XML parser save the XMLreader node properties (baseURI, localName, name, namespaceURI, prefix) for each XML (Dto) element as 'XMLattributes' as well as XML attributes (xmlns, xmlns:*, schemaLocation), if set (more info below).

'any' [XSD] elements are accepted as 'Anytype' object instances (more info below, 'AnyType').

Usage, build up structure

To build up dsig structure:

<?php
namespace Kigkonsult\DsigSdk;
use Kigkonsult\DsigSdk\Dto\AnyType;
use Kigkonsult\DsigSdk\Dto\CanonicalizationMethodType;
use Kigkonsult\DsigSdk\Dto\KeyInfoType;
use Kigkonsult\DsigSdk\Dto\SignedInfoType;
use Kigkonsult\DsigSdk\Dto\SignatureType;
use Kigkonsult\DsigSdk\Dto\SignatureValueType;

$dsig = SignatureType::factory()
    ->setSignedInfo( 
        SignedInfoType::factory()
            ->setCanonicalizationMethod(
                CanonicalizationMethodType::factory()
                    ->setAlgorithm( SignatureType::MINICANONICAL )
                    ->setAny( [
                        AnyType::factory()
                            ->setElementName( 'nonSchemaElement1')
                            ->setAttributes( [
                                'id' => '12345' 
                                ] )
                             ->setContent( 'Lr1mKGxP7VAgMB...' ),
                        AnyType::factory()
                            ->setElementName( 'nonSchemaElement2')
                            ->setSubElements( [
                                AnyType::factory()
                                    ->setElementName( 'nonSchemaElement3')
                                    ->setContent( 'Lr1mKGxP7VAgMB...' ),
                            ] )
                        ]
                    )
            )
    )
    ->setSignatureValue(
        SignatureValueType::factory()
            ->setSignatureValueType( 'vgGZnRlm8...' )
    )
    ->setKeyInfo(
        KeyInfoType::factory()
            ->setKeyInfoType( [
                [                 // one set of elements
                    [             // element
                        SignatureType::X509DATA => 
                            X509DataType::factory()
                                ->setX509Certificate( ... )
                    ],
                ],
        ] )
    )
    ->setObject(
        ...
    )
    ...
XML attributes

You can set (single 'element') XMLattribute using

        $dsig->setXMLAttribut( ,  );
    

To set (ex. prefix) and 'propagate' down in hierarchy:

        $dsig->setXMLAttribut( SignatureType::PREFIX, , true );
    

You can remove (single 'element') XMLattribute using

        $dsig->unsetXMLAttribut(  );
    

To unset (ex. prefix) and 'propagate' down in hierarchy:

        $dsig->unsetXMLAttribut( SignatureType::PREFIX, true );
    

To fetch and iterate over XMLAttributes

        foreach( $dsig->getXMLAttributes() as $key => $value {
        ...
        }
    
Anytype

Anytype object instances are used for 'any' [XSD] elements.

The element name are stored and fetched with

        $anytype->setElementName(  );
    
        $anytypeName = $anytype->getElementName();
    

The 'any' [XSD] element attributes may include XML attributes.

The AnyType attributes are stored and fetched as array.

        $anytype->setAttributes( [  =>  ] );
    
        foreach( $anytype->getAttributes() as $key => $value {
        ...
        }
    

Note, an AnyType instance may have

content
type string,
AnyType::setContent()
AnyType::getContent()
 

or

sub-elements
type array [*AnyType]
AnyType::setSubElements()
AnyType::getSubElements()

but not both.

Usage, output as XML

DsigSdk uses XMLWriter creating output.

        $XMLstring = DsigWriter::factory()->write( $dsig );
    
The XMLwriter adds for each element
element name with prefix, if exists
XMLattribute xmlns, xmlns:* and schemaLocation, if exists.
Usage, output as DomNode
$domNode = DsigWriter::factory()->write( $dsig, true );
