FeedForAll has an advanced search and replace feature that is useful for making global updates to a feed. For example, if your Web site layout changes use search and replace to update your feed to the new link addresses. To access the 'Search' window, choose 'Search' from the 'Edit' menu.
Use the 'Search In' section to only perform the search in a particular tab, or in all sections of your feed.
Use the 'Freeze Dates' option to make replacements, without the Pub Dates being automatically updated.
