Advanced Excerpt

In addition to keeping HTML markup in the excerpt, the plugin also corrects HTML that might have been broken due to the trimming process.

Installation

Unpack and upload it to the /wp-content/plugins/ directory.
Activate the plugin through the 'Plugins' menu in WordPress.

Features:

• It can keep HTML markup in the excerpt (and you get to choose which tags are included)
• It trims the excerpt to a given length using either character count or word count
• You can customise the excerpt length and the ellipsis character that will be used when trimming
• The excerpt length is real (ie. "words" and characters belonging to HTML tags are not counted)
