I am using the SharePoint REST API to construct the endpoint URI as mentioned here

Working with folders and files with REST

I have a Microsoft SharePoint location which has a folder and the folder contains multiple files. I used the following:

https://xyz.sharepoint.com/teams/Data/_api/web/GetFolderByServerRelativeUrl('/teams/Data/Shared Documents/TestFolder/2020-12-14')/files

The above returns the following XML response

          ----------
         ----------
      </entry>
      </feed> 

There is a lot of unnecessary information here for my end goal. I only want the service call to return the information for <ContentTag> </ContentTag> for all <entry> </entry>.

How can I construct the URI to return the following desired output. Is there any way to use XQuery like path expression to get to what I want?

Thank you in advance.

Use below endpoint:

https://xyz.sharepoint.com/teams/Data/_api/web/GetFolderByServerRelativeUrl('/teams/Data/Shared Documents/TestFolder/2020-12-14')/files?$select=ContentTag

    thanks for the solution. It worked. I initially thought that SQL like select statement only works on sharepoint lists. I am surprised to see that it works on XML structure as well. – smpa01 Dec 16 '20 at 13:55
