On the one hand - I wanted to move old entries in from a very old, static, page as plain old (did I mention it was old) HTML. In other words, the old HTML from the static junk-drawer page (back when Netscape 4.x was king of the world) needed to be cut and pasted into the entry area and simply display as if it were html placed directly in the blog-page.
On the other hand - I didn't want to give up the modern convenience of being able to use s9y's Line-feed-to-break-tag plug-in for new entries going forward.
Solution! - Add suppresslf (suppressLF) to the list of exceptions in the NL2BR tool. Now, if I want to cut and paste-in html of any kind I start with <suppresslf> </suppresslf> and then Ctrl-V the html text in between them. Will it work you ask? YES, IT DOES!
But (there's always a but) - S9y's display functionality fixes old <p> tags, AND stand-alone <p/> tags, by producing a "real" block of text. That is, the display function subsumes the text that follows the tag. The practical effect is that something like: "<p /> hello world", is turned into "<p>hello world</p>".
So you still have to do a little fixup - Replacing the original <p> or <p /> tags with "<p></p>" pairings.. Still much better than manually retyping the whole thing in. No?
Also, you now have a custom tag <suppresslf> in your output html. This is well within the standard unless you want your pages to be well-formed and valid (good luck with that obsession ). Even in the event you are even more OCD than me, you could still achieve this, simply by pointing to your own DTD that includes a definition of your new tag.
P.S. This message is the first attempt to employ BBCodes (there's a plug-in for that). There will likely be some learning to do for that as well.
