domparser

Wrappers for the PHP DOMDocument class to provide extra functionality for html/xml parsing, _(*1)

, _(*2)

Constructor Arguments

There are 2 constructors available, one for the HtmlParser class and one for the XmlParser class, they both work in the same way. * Only 1 parameter is available, which should be passed as a string, and contain the content to parse (xml/html) * Warnings are captured during the loading of the content using libxml_use_internal_errors() and libxml_get_errors(), these are available from the errors property after the class has been initiated, _(*3)

Public Properties

html/xml (string) - Depending on which class was used one of these properties will be present and contain the content used for parsing
errors (array) - If any errors were encountered during parsing they will be in this array (see [Constructor Arguments])
dom (DOMDocument) - This is the internal instance of the DOMDocument class used
mode (string) - Indicates whether the parser is operating in html or xml mode

Public Methods

getTags(string $tagName): array - Similar to DOMDocument::getElementsByTagName() except a standard array is returned.
Alias: getElementsByTagName()
getTag(string $tagName): Element - Similar to getTags() but will return the first element matched, instead of an array of elements.
Alias: getElementByTagName()
getElementsByClassName(mixed $className): array - Matches elements that have a class attribute that matches the string parameter.
If you want to find elements with multiple classes, pass the $className as an array of classes, and only elements that have all classes will be returned
getElementByClassName(mixed $className): Element - Similar to getElementsByClassName() except this will return the first element matched
output(): string - Returns the xml/html repesented by the receiver, formatted using DOMDocument::formatOutput
xpath(string $path): array - Returns an array of elements matching the $path

Dom Elements

All of the methods that return elements return them as instances of the Element class, this acts similarly to the standard DOMElement class, except it has all of the above methods available, and the nodeValue property has leading and trailing whitespace removed using trim(), _(*4)

Examples

The parser classes use a namespace of duncan3dc\Dom, _(*5)

use duncan3dc\Dom\Html\Parser;
use duncan3dc\Dom\Xml\Parser;

$parser = new Parser(file_get_contents("http://example.com"));

echo "Page Title: " . $parser->getTag("title")->nodeValue . "\n";

$contentType = false;
$meta = $parser->getTags("meta");
foreach($meta as $element) {
    if($element->getAttribute("http-equiv") == "Content-type") {
        $contentType = $element->getAttribute("content");
    }
}
echo "Content Type: " . (($contentType) ?: "NOT FOUND") . "\n";
