Please advice.

The declare.txt and the header of feed.txt must be identical (including the field contents),
then feed.txt won't be changed.
So I have understood the original requirement.

Also, in feed.txt the number of fields must be consistent.
In your previous example, the header has not got the "updated_at" and "created_at", so the script does not work correctly (it then strips off the last two columns):
Code:
awk -F\; '{print NF}' feed.txt
72
74

74

   module_loaded
       Return true if the module is loaded.

NAME
MojoMojo::Formatter::RSS - Include RSS feeds on your page. DESCRIPTION
This formatter takes a feed in the format {{feed <url>}}, and passes it through XML::Feed to get a formatted feed suitable for inclusion in your page. It also caches them in the chosen Catalyst cache. By default it will render the first element in the feed, but it can take a numeric parameter to choose number of elements. METHODS
format_content_order Format order can be 1-99. The RSS formatter runs on 6, after the Include), so that transcluding a page from the wiki that brings in a feed, will display the feed in the transcluded section as well. format_content Calls the formatter. Takes a ref to the content as well as the context object. include_rss <c> <url> [<entries>] Returns HTML-formatted feed content for inclusion, up to a specified number of entries. Will store a cached version in "$c->cache". SEE ALSO
