Question

I am using YQL to parse multiple rss feeds. I have success getting YQL to return the XML for title,link,date but it also pulls in dc:title which makes for duplicate results. I have tried using dc:title but get a syntax error. Here’s the YQL statement.

    select title,link,description,date from rss where url in (
    'http://somerssfeed.com',
    'http://somerssfeed.com'
) | sort(field="date", descending="true")

What would be the correct syntax to use dc:title?
Also, is it possible for YQL to rename dc:title in the xml output to just title?

Answer 1

As you have seen, YQL ignores namespaces when you specify the projection (the fields to retrieve). So, the correct syntax is what you already have; you cannot differentiate the title and dc:title fields in the manner that you want.

You could however manipulate the data in any way that you like (including removing, renaming, reordering of fields/results) in a bespoke data table.

If that sounds like too much hard work, you could append a unique() filter to the end of your existing query to return only one result per unique title/dc:title, to merge the duplicates that you are getting, like … | unique(field="title").
