This library extends the native PHP DOMDocument providing methods described by the Microdata and
DOM API specifications to support finding microdata items and describing their properties. It is well covered by
tests and tries to be efficient as it traverses the DOM.
For a document with microdata, use MicrodataDOM\DOMDocument. It works just like a regular DOMDocument, but has the
extra microdata accessors. The following example...
$dom = new MicrodataDOM\DOMDocument();
$dom->loadHTMLFile('http://dpb587.me/about.html');
// find Person types and get the first item
$dpb587 = $dom->getItems('http://schema.org/Person')->item(0);
echo $dpb587->itemId;
// items are still regular DOMElement objects
printf(" (from %s on line %s)\n", $dpb587->getNodePath(), $dpb587->getLineNo());
// there are a couple ways to access the first value of a named property
printf("givenName: %s\n", $dpb587->properties['givenName'][0]->itemValue);
printf("familyName: %s\n", $dpb587->properties['familyName']->getValues()[0]);
// or directly get the third, property-defining DOM element
$property = $dpb587->properties[3];
printf("%s: %s\n", $property->itemProp[0], $property->itemValue);
// use the toArray method to get a Microdata JSON structure
echo json_encode($dpb587->toArray(), JSON_UNESCAPED_SLASHES) . "\n";
Will output something like...
http://dpb587.me/ (from /html/body/article/section on line 97)
givenName: Danny
familyName: Berger
jobTitle: Software Engineer
{"id":"http://dpb587.me/","type":["http://schema.org/Person"],"properties":{"givenName":["Danny"],...snip...}
You can install this library via composer...
$ composer install dpb587/microdata-dom
You can find runtime code in src and test code in tests/src. If you are making changes, you
should already have PHPUnit installed before running the tests...
$ phpunit
Alternatively, have your Concourse execute the tests with your local bits...
$ fly execute -c ci/tasks/test.yml -i repo=$PWD -x
Builds are publicly accessible on Travis CI and internally with Concourse.
