In the example you gave it might look a bit odd if the content suggests it was originally a list. * Access the extracted content through the DOM, and grab the textual content you need using node values. That way, you can limit it to a specific character count of content, and with a bit of work, you can preserve the original markup tags too Thanks, Ash http://www.ashleysheridan.co.uk
