Detailed Description

This filter extracts <style> blocks from input HTML, cleans them up using CSSTidy, and then places them in $purifier->context->get('StyleBlocks') so they can be used elsewhere in the document.

Note

See tests/HTMLPurifier/Filter/ExtractStyleBlocksTest.php for sample usage.

This filter can also be used on stylesheets not included in the document–something purists would probably prefer. Just directly call HTMLPurifier_Filter_ExtractStyleBlocks->cleanCSS()
