XML source for cuyz/valinor
A Composer library that provides an additional XML source for use with
the popular cuyz/valinor
library.
This allows to easily map XML files or contents to any signature supported
by Valinor, e.g. objects or special array shapes. It leverages the
mtownsend/xml-to-array
library to convert raw XML to a reusable array structure.
🔥 Installation
composer require eliashaeussler/valinor-xml
⚡ Usage
Given the following XML:
<?xml version="1.0" encoding="UTF-8"?> <person> <name>Dr. Zane Stroman</name> <address> <street>439 Karley Loaf</street> <postcode>17916</postcode> <city>West Judge</city> <country>Falkland Islands (Malvinas)</country> </address> <contact> <phone>827-986-5852</phone> </contact> </person>
These are the resulting classes:
final readonly class Address { public function __construct( public string $street, public string $postcode, public string $city, public string $country, ) {} } final readonly class Contact { public function __construct( public string $phone, ) {} } final readonly class Person { public function __construct( public string $name, public Address $address, public Contact $contact, ) {} }
Mapping from XML string
In order to map the given XML to the Person
class, you need
to follow these three steps:
- Create a new mapper as written in Valinor's documentation
- Parse and prepare your XML using the shipped
XmlSource
- Use the mapper to map your XML to the
Person
class
use CuyZ\Valinor; use EliasHaeussler\ValinorXml; $mapper = (new Valinor\MapperBuilder())->mapper(); $source = ValinorXml\Mapper\Source\XmlSource::fromXmlString($xml); $person = $mapper->map(Person::class, $source); // instanceof Person
The resulting object will look something like this:
object(Person)#180 (3) {
["name"]=>
string(16) "Dr. Zane Stroman"
["address"]=>
object(Address)#135 (4) {
["street"]=>
string(15) "439 Karley Loaf"
["postcode"]=>
string(5) "17916"
["city"]=>
string(10) "West Judge"
["country"]=>
string(27) "Falkland Islands (Malvinas)"
}
["contact"]=>
object(Contact)#205 (1) {
["phone"]=>
string(12) "827-986-5852"
}
}
Mapping from XML file
The XML can also be read from an external file:
use CuyZ\Valinor; use EliasHaeussler\ValinorXml; $mapper = (new Valinor\MapperBuilder())->mapper(); $source = ValinorXml\Mapper\Source\XmlSource::fromXmlFile($file); $person = $mapper->map(Person::class, $source); // instanceof Person
Convert nodes to collections
Sometimes it might be necessary to always convert XML nodes to collections. Given the following XML:
<?xml version="1.0" encoding="UTF-8"?> <community> <member><!-- ... --></member> <!-- NOTE: There's only one member --> </community>
Let's assume you want to map this XML to the following class:
final readonly class Community { /** * @param list<Person> $member */ public function __construct( public array $member, ) {} }
You will recognize that this does not work as expected when using the above mapping method:
use CuyZ\Valinor; use EliasHaeussler\ValinorXml; $mapper = (new Valinor\MapperBuilder())->mapper(); $source = ValinorXml\Mapper\Source\XmlSource::fromXmlFile($file); $person = $mapper->map(Community::class, $source); // throws exception
It will instead throw an exception like this:
CuyZ\Valinor\Mapper\TypeTreeMapperError: Could not map type `Community` with value array{member: array{…}}.
This is because the XML converter does not know whether <member>
should
be a collection or if it's just a "normal" node. That's why the XmlSource
provides an appropriate method to convert such nodes to collections:
use CuyZ\Valinor; use EliasHaeussler\ValinorXml; $mapper = (new Valinor\MapperBuilder())->mapper(); $source = ValinorXml\Mapper\Source\XmlSource::fromXmlFile($file) ->asCollection('member') ; $person = $mapper->map(Community::class, $source); // instanceof Community
The resulting object will look something like this:
object(Community)#76 (1) {
["member"]=>
array(1) {
[0]=>
object(Person)#126 (3) {
["name"]=>
string(16) "Dr. Zane Stroman"
["address"]=>
object(Address)#170 (4) {
["street"]=>
string(15) "439 Karley Loaf"
["postcode"]=>
string(5) "17916"
["city"]=>
string(10) "West Judge"
["country"]=>
string(27) "Falkland Islands (Malvinas)"
}
["contact"]=>
object(Contact)#252 (1) {
["phone"]=>
string(12) "827-986-5852"
}
}
}
}
However, this is only relevant if only one node of the collection exists in your XML. If the XML contains more than one node, the XML converter properly converts them to a collection:
use CuyZ\Valinor; use EliasHaeussler\ValinorXml; $xml = <<<XML <?xml version="1.0" encoding="UTF-8"?> <community> <member><!-- ... --></member> <member><!-- ... --></member> <member><!-- ... --></member> </community> XML; $mapper = (new Valinor\MapperBuilder())->mapper(); $source = ValinorXml\Mapper\Source\XmlSource::fromXmlString($xml); $person = $mapper->map(Community::class, $source); // instanceof Community
