Answer 1

first you'd have to know a little about XML. namely:

• Reading XML, what is a tag, node, attribute, etc. A cursory search on the web for "Learn XML" produced: https://www.w3schools.com/xml/
• The next step is understanding a little XPath. XPath is a query language used on XML. again, web search: https://www.w3schools.com/xml/xml_xpath.asp
• The third piece to this puzzle is how to incorporate this into C#. a short web search of "read xml c# xpath" revealed this tidbit. Using XPath to parse an XML document

this is a basic web search research project. this is the way I learned most of my programming, by searching the web, reading, learning.

Learning to research is probably the most important skill of a modern day programmer.
