To get the values for the "name" AND "industry" tag you can use:


You can easily get to the expression inside Cases[improvements,expr->
{name, value}, Infinity] by

(1) evaluating your variable improvements
(2) selecting the expression XElement[improvement, ...]; the "
characters for the strings are inserted automatically
(3) replacing the actual names (e.g. "Basic Factory") by name_
(4) replacing the actual industry (e.g. "10") by industry_

Note that there is an error in the example you give (it should read
"industry" instead of "Industry").
