I’m getting a list from RSS and another list from Mongo. I need to filter all items that don’t exist in Mongo and then process them. What would be the solution to this?
- Read RSS feed
- Filter by keywords
- Check if article link already exist in the database
- If (not found)
- Insert to db
- Send to a webhook
What I’ve Tried:
I attempted to pass input data from Node 2 to Node 4 at the same time as Node 3 to Node 4 to check against but I can’t seem to extract key/values and merge them into a single array variable. This causes items from List A to be checked against one criteria only from List B resulting in false positives
Is it possible to use a Function node to compare 2 items lists?
Or have Mongo/Postgres continue if nothing is found? With number of rows/items found for Context would be helpful too
