JChecker for Mac

From Artman21 Inc.:

JChecker3.0 is not only a HTML checker but has been reborn as a powerful HTML source code editor supporting both the Mac OS Classic and OS X environment. As an HTML checker, JChecker3.0 supports 16 HTML/XHTML validation dictionaries, auto-generation for DTD dictionaries, auto HTML error correction, powerful link checking including sub linked pages, and much more. As a text editor, it inherits powerful editing functions from its brother Jedit, including regular expression search, AppleScriptability, and enhanced macro functions. It also supports many original functions such as a tag editing macro, a tag help macro, and a services menu under OS X web server.
