With some of the recent XHTML cleanup I've been doing of the OPAC, I had become aware that mod_xmlent was treating every element as though it would contain content, and therefore changed empty elements like <link blah />, <img blah />, and <br /> to <link blah></link>, <img blah></img>, and <br></br>.
Not heinous, but I figured we should be able to do better than that. So I pulled the list of empty elements from xhtml1-transitional.dtd and modified mod_xmlent.c to treat empty elements properly. I'm posting this to the list rather than applying it directly in case my semi-rusty C has any obvious "oops!" moments in it. If there's no objection or stated need for reworking the patch, I'll apply it in a day or two. -- Dan Scott Laurentian University
