To do this correctly, you're going to basically need to do one of two things:
1 - strip all HTML out of the shortened version and only show plain text (convert <BR> and <P> tags to new lines, then use regex to remove all HTML, then truncate to length). 2 - parse the HTML, count the non-html characters, keeping track of which tags are open, and when you get to the number of characters where you want to cut it off, close all of your open HTML tags. If you don't do one of those two things, you will end up with open tags really messing up your page. -- Jeremy Thomerson http://www.wickettraining.com On Thu, Jan 1, 2009 at 1:09 PM, jchappelle <[email protected]> wrote: > > I have strings in a databse that are raw html text and it is being > displayed > on a blog page.
