How to access attributes of an article using REST API

Content

Hi,

We have some attributes defined inside answer in Agent Desktop. Some of the attributes are <Title>, <Regulations>, <Change_Type> etc.. So, when we create an article in Authoring, we can set the values for these attributes and save the article.

For some business requirement, we need to fetch all the articles having a specific value, say "N/A" inside <Regulations> attribute using REST API
We tried the following Content REST API call with <title> attribute in the query parameter. It worked.
