htmlpurifier/library/HTMLPurifier/Printer.php
Edward Z. Yang 73a1e31fad [1.3.0] Added spiffy new smoketest printDefinition.php, which lets you twiddle with the configuration settings and see how the internal rules are affected. (currently only complete for HTMLDefinition).
- HTMLPurifier -> HTML Purifier
. HTMLPurifier_Config->getBatch($namespace) added
. More lenient casting to bool from string in HTMLPurifier_ConfigSchema
. <?xml ... tags added to all smoketests
