XPath Node Vs Attribute as DataSource

Is it possible to bring in a single XPath attribute rather than a node as a data source? I have an issue with the XML file/data I receive for a production that I think could be solved if my data source is only showing one attribute rather than an entire spreadsheet of various attributes under that node.
For example: XPath = //bsgame/team[1]/player/hitting (this brings in all baseball batting data attributes and works but not for my application since some needed attributes only display when there is a value - EX: there is no attribute for "strikeout" [@so] until someone actually strikes out so AUTO COLUMN will always find the wrong data field until it exists)
I need a working XPath with attribute: //bsgame/team[1]/player/hitting@so - returns ERROR: Object reference not set to an instance of an object.
My new idea is to have one attribute to display at a time in the data source so that I can lock it to the source rather than a column.
I have no control over the XML file and was told there can be no changes made to what I receive.
Is there a way to get just one attribute? Other ideas for a solution?

Other ideas for a solution? if an attiribute is missing you will always get an erro in vMix ( datasources) One can however check an xpath in a script (see vb.net) and trap the "error" so one can decide what to do when the att is available or not https://www.w3schools.com/xml/xpath_syntax.asp
