embedvslxml
PHP library to get information from any web page (using oembed, opengraph, twitter-cards, scrapping the html, etc). It's compatible with any web service (youtube, vimeo, flickr, instagram, etc) and has adapters to some sites like (archive.org, github, facebook, etc).
lxml is a low-level XML and HTML tree processor. It's used by many other libraries such as parsel or beautifulsoup for higher level HTML parsing.
One of the main features of lxml is its speed and efficiency.
It is built on top of the libxml2 and libxslt C libraries, which are known for their high performance and low memory footprint.
This makes lxml well-suited for processing large and complex XML and HTML documents.
One of the key components of lxml is the ElementTree API, which is modeled after the ElementTree API from the Python standard library's xml module. This API provides a simple and intuitive way to access and manipulate the elements and attributes of an XML or HTML document. It also provides a powerful and flexible Xpath engine that allows you to select elements based on their names, attributes, and contents.
Another feature of lxml is its support for parsing and creating XML documents using the XSLT standard. The lxml library provides a powerful and easy-to-use interface for applying XSLT stylesheets to XML documents, which can be used to transform and convert XML documents into other formats, such as HTML, PDF, or even other XML formats.
For web scraping it's best to use other higher level libraries that use lxml like parsel or beautifulsoup
Highlights
Example Use
use Embed\Embed;
$embed = new Embed();
//Load any url:
$info = $embed->get('https://www.youtube.com/watch?v=PP1xn5wHtxE');
//Get content info
$info->title; //The page title
$info->description; //The page description
$info->url; //The canonical url
$info->keywords; //The page keywords
$info->image; //The thumbnail or main image
$info->code->html; //The code to embed the image, video, etc
$info->code->width; //The exact width of the embed code (if exists)
$info->code->height; //The exact height of the embed code (if exists)
$info->code->ratio; //The aspect ratio (width/height)
$info->authorName; //The resource author
$info->authorUrl; //The author url
$info->cms; //The cms used
$info->language; //The language of the page
$info->languages; //The alternative languages
$info->providerName; //The provider name of the page (Youtube, Twitter, Instagram, etc)
$info->providerUrl; //The provider url
$info->icon; //The big icon of the site
$info->favicon; //The favicon of the site (an .ico file or a png with up to 32x32px)
$info->publishedTime; //The published time of the resource
$info->license; //The license url of the resource
$info->feeds; //The RSS/Atom feeds
from lxml import etree
# this is our HTML page:
html = """
<head>
<title>Hello World!</title>
</head>
<body>
<div id="product">
<h1>Product Title</h1>
<p>paragraph 1</p>
<p>paragraph2</p>
<span class="price">$10</span>
</div>
</body>
"""
tree = tree.fromstring(html)
# for parsing, LXML only supports XPath selectors:
tree.xpath('//span[@class="price"]')[0].text
"$10"
