XSLT Component

The XSLT component can be used to transform an XML document into something else based on XSLT templates.

Example

use VeeWee\Xml\Dom\Document;
use VeeWee\Xml\Xslt\Processor;
use VeeWee\Xml\Xslt\Configurator;

$processor = Processor::fromTemplateDocument(
    Document::fromXmlFile('xml-to-yaml-converter.xslt'),
    Configurator\all_functions(),
    Configurator\parameters('', [
        'name' => 'Jos',    
    ])
);
$doc = Document::fromXmlFile('data.xml');

echo $processor->transformDocumentToString($doc);

It consists out of following components:

• Configurators: Specify how you want to process your XSLT templates.
• Loaders: Determine where the load the XSLT template from.
• Transformers: Specify what you want to transform to which kind of output.

Configurators

Specify how you want to process your XSLT templates.

all_functions

Registers all known PHP functions to the XSLTProcessor object, allowing you to use php:function('ucfirst',string(uid)) inside your XSLT Template.

use VeeWee\Xml\Dom\Document;
use VeeWee\Xml\Xslt\Processor;
use function VeeWee\Xml\Xslt\Configurator\all_functions;

$processor = Processor::fromTemplateDocument(
    Document::fromXmlFile('xml-to-yaml-converter.xslt'),
    all_functions()
);

functions

Registers specific PHP functions to the XSLTProcessor object, allowing you to use php:function('ucfirst',string(uid)) inside your XSLT Template.

use VeeWee\Xml\Dom\Document;
use VeeWee\Xml\Xslt\Processor;
use function VeeWee\Xml\Xslt\Configurator\functions;

$processor = Processor::fromTemplateDocument(
    Document::fromXmlFile('xml-to-yaml-converter.xslt'),
    functions(['ucfirst'])
);

loader

The loader configurator takes a loader to specify the source of the XSLT Template.

use VeeWee\Xml\Xslt\Processor;
use function VeeWee\Xml\Xslt\Configurator\loader;
use function VeeWee\Xml\Xslt\Loader\from_template_document;

$processor = Processor::configure(
    loader(from_template_document($template))
);

parameters

Registers a map of key/value parameters to the XSLTProcessor which can be used inside your template.

use VeeWee\Xml\Dom\Document;
use VeeWee\Xml\Xslt\Processor;
use function VeeWee\Xml\Xslt\Configurator\parameters;

$processor = Processor::fromTemplateDocument(
    Document::fromXmlFile('xml-to-yaml-converter.xslt'),
    parameters('namespace', [
        'name' => 'Jos'
    ])
);

profiler

Specify a file in which you want to profile the XSLT processor.

use VeeWee\Xml\Dom\Document;
use VeeWee\Xml\Xslt\Processor;
use function VeeWee\Xml\Xslt\Configurator\profiler;

$processor = Processor::fromTemplateDocument(
    Document::fromXmlFile('xml-to-yaml-converter.xslt'),
    profiler('profiler-info.txt')
);

security_preferences

Specify which security preferences you want to use inside the XSLT processor.

use VeeWee\Xml\Dom\Document;
use VeeWee\Xml\Xslt\Processor;
use function VeeWee\Xml\Xslt\Configurator\security_preferences;

$processor = Processor::fromTemplateDocument(
    Document::fromXmlFile('xml-to-yaml-converter.xslt'),
    security_preferences( XSL_SECPREF_DEFAULT )
);

Loaders

Determine where the load the XSLT template from.

from_template_document

use VeeWee\Xml\Dom\Document;
use VeeWee\Xml\Xslt\Processor;

$template = Document::fromXmlFile('xml-to-yaml-converter.xslt');
$processor = Processor::fromTemplateDocument($template, ...$configurators);

Transformers

Specify what you want to transform to which kind of output.

document_to_string

Transforms the input Document based on the selected XSLT template into a string.

use VeeWee\Xml\Dom\Document;
use VeeWee\Xml\Xslt\Processor;

$template = Document::fromXmlFile('xml-to-yaml-converter.xslt');
$document = Document::fromXmlFile('data.xml');

$processor = Processor::fromTemplateDocument($template);
$text = $processor->transformDocumentToString($document);
