Hello Mona,
thank you for the answer.
I'm aware of theWorkflow definition language (WDL) and also that we can specify the number of days in this specific example.
My question is not about how to use this example and to customize it to fit my need, but more about how the author knew that:
in the object returned by the List_all_RSS_feed_item action , the objects stored in the body had a column ['publishDate] ?
When I check the raw RSS (see https://sergeluca.wordpress.com/feed/), I only see "pubdate" and not ['publishDate'] ; does that mean that the List_all_RSS_feed_item action internally create an array of object with a column ['publishDate'] instead of ["pubdate"] as we can find in the raw rss feed for blog post ? If that is the case where is it described in the documentation of this action ? or how did he author of the post knew it ?
This is not described in the WDL documentation.
