(Perl) Generate XHTML on the command line with XML::API::XHTML

Sun, 10 Feb 2008 02:21:23 GMT

Build a simple XHTML document, format it with Tidy and print the result to "temp.html." You may first need to `cpan XML::API::XHTML`, and install Tidy using your favorite package manager, or just [download Tidy by itself](http://tidy.sourceforge.net/#binaries) ### If you can't install XML::API::XHTML On my system, CPAN complained that "make test had returned bad status" during installation of XML::API::XHTML. To solve this I started the CPAN shell (just type `cpan`) and then forced the install, like this: cpan> force XML::API::XHTML

Sun, 09 Dec 2007 21:16:58 GMT

Hypothetically, the following command should return a list of the top 500 or so hits in Google for onemorebug.com. The results will be prepended with digits, followed by a dot and some whitespace (Lynx adds these). _You must have Lynx and Wget installed on your system for this to work._ Keep in mind that *nix shells don't like it when you double-quote strings, see the comments.

Besides DOCTYPE, other strings to search for include "discarding", "lacks value" and "Error:" Remember to replace MY_DOMAIN with the actual domain you want to validate against.
