如何解析 HTML/XML 并从中提取信息?
最佳答案
原生 XML 扩展
我更喜欢使用 native XML extensions 之一由于它们与 PHP 捆绑在一起,因此通常比所有 3rd 方库都快,并为我提供了对标记所需的所有控制。
DOM
The DOM extension allows you to operate on XML documents through the DOM API with PHP 5. It is an implementation of the W3C's Document Object Model Core Level 3, a platform- and language-neutral interface that allows programs and scripts to dynamically access and update the content, structure and style of documents.
The XMLReader extension is an XML pull parser. The reader acts as a cursor going forward on the document stream and stopping at each node on the way.
This extension lets you create XML parsers and then define handlers for different XML events. Each XML parser also has a few parameters you can adjust.
The SimpleXML extension provides a very simple and easily usable toolset to convert XML to an object that can be processed with normal property selectors and array iterators.
FluentDOM provides a jQuery-like fluent XML interface for the DOMDocument in PHP. Selectors are written in XPath or CSS (using a CSS to XPath converter). Current versions extend the DOM implementing standard interfaces and add features from the DOM Living Standard. FluentDOM can load formats like JSON, CSV, JsonML, RabbitFish and others. Can be installed via Composer.
Wa72\HtmlPageDom
is a PHP library for easy manipulation of HTMLdocuments using DOM. It requires DomCrawler from Symfony2components for traversingthe DOM tree and extends it by adding methods for manipulating theDOM tree of HTML documents.
phpQuery is a server-side, chainable, CSS3 selector driven Document Object Model (DOM) API based on jQuery JavaScript Library written in PHP5 and provides additional Command Line Interface (CLI).
Zend_Dom provides tools for working with DOM documents and structures. Currently, we offer Zend_Dom_Query, which provides a unified interface for querying DOM documents utilizing both XPath and CSS selectors.
QueryPath is a PHP library for manipulating XML and HTML. It is designed to work not only with local files, but also with web services and database resources. It implements much of the jQuery interface (including CSS-style selectors), but it is heavily tuned for server-side use. Can be installed via Composer.
fDOMDocument extends the standard DOM to use exceptions at all occasions of errors instead of PHP warnings or notices. They also add various custom methods and shortcuts for convenience and to simplify the usage of DOM.
sabre/xml is a library that wraps and extends the XMLReader and XMLWriter classes to create a simple "xml to object/array" mapping system and design pattern. Writing and reading XML is single-pass and can therefore be fast and require low memory on large xml files.
FluidXML is a PHP library for manipulating XML with a concise and fluent API.It leverages XPath and the fluent programming pattern to be fun and effective.
- An HTML DOM parser written in PHP5+ lets you manipulate HTML in a very easy way!
- Require PHP 5+.
- Supports invalid HTML.
- Find tags on an HTML page with selectors just like jQuery.
- Extract contents from HTML in a single line.
PHPHtmlParser is a simple, flexible, html parser which allows you to select tags using any css selector, like jQuery. The goal is to assiste in the development of tools which require a quick, easy way to scrape html, whether it's valid or not! This project was original supported by sunra/php-simple-html-dom-parser but the support seems to have stopped so this project is my adaptation of his previous work.
- A universal tokenizer and HTML/XML/RSS DOM Parser
Ability to manipulate elements and their attributes
Supports invalid HTML and UTF8
Can perform advanced CSS3-like queries on elements (like jQuery -- namespaces supported)
- A HTML beautifier (like HTML Tidy)
Minify CSS and Javascript
Sort attributes, change character case, correct indentation, etc.
- Extensible
Parsing documents using callbacks based on current character/token
Operations separated in smaller functions for easy overriding
- Fast and Easy
A Python and PHP implementations of a HTML parser based on the WHATWG HTML5 specification for maximum compatibility with major desktop web browsers.
ScraperWiki's external interface allows you to extract data in the form you want for use on the web or in your own applications. You can also extract information about the state of any scraper.
