Using web.content xml to stage data then reference it for multiple queries

1. Original query to get the unique code (D20171031T115921-CBTFFOOKL) for users as seen in step two:

= Xml.Tables(Web.Contents("http://gsa-scan01:8080/api/users/", [Headers=[Authorization="ApiKey ad2a1ed1-dec1-4c2b-ba60-5f7397932bee", Accept="application/xml"]]))

2. New web.content url query with unique code and /metadata/

http://********:8080/api/users/22/queued/D20171031T115921-CBTFFOOKL/metadata/

Step two is where I run into an issue about building a query. I am so close to getting this dashboard data imported but this has had me stumped for over a week! Thank you ahead of time!
