I have been developing Java programs that parse html source code of webpages by using various html parsers like Jericho, NekoHtml etc...
Now I want to develop parsers in PHP language. So before starting, I want to know that are there any html parsers available that I can use with PHP to parse html code
The builtin class DOM parser does a very good job. There are many other xml parsers, too.
Check out DOMDocument.
Example #1 Creating a Document
<?php
$doc = new DOMDocument();
$doc->loadHTML("<html><body>Test<br></body></html>");
echo $doc->saveHTML();
DOM is pretty good for this. It can also deal with invalid markup, however, it will throw undocumented errors and exceptions in cases of imperfect markup so I suggest you filter HTML with HTMLPurifier or some other library before loading it with the DOM.
