The syndicated_item_excerpt hook allows you to write filters which alter or act on the excerpt for posts that are syndicated by FeedWordPress. The hook passes two parameters to any registered filter functions: a string containing the excerpt for the item (as taken from the syndication feed) and an object of class SyndicatedPost representing the syndicated item as a whole.

Filter functions should return a string containing the filtered excerpt to be imported into the WordPress database. If the filter returns an empty value, WordPress will generate an excerpt automatically from the post content.

Sample

This example filter will ensure that any HTML tags will be stripped out of the excerpts taken from the syndicated feed.
