Is there a more elegant way to substring?

Here is my code

file_name = Dir['path/xml/test/*.txt']
file_name.to_s # => ["path/xml/test/test.txt"]

I want to return:

"test"

I can do it with the code below:

file_name = Dir['path/xml/test/*.txt']
file_name.to_s[15,60].gsub(/.txt["]/,"").gsub(/]/,"")

But it is not very elegant. Is there a more elegant way to just return the filename without .txt and []?

Yes.

File.basename(Dir['path/xml/test/*.txt'].first, ".txt")
# => "test"

To do it for all files,

Dir['path/xml/test/*.txt'].map{|e| File.basename(e, ".txt")}

Also possible in case there are more files ...

Dir[ 'path/name/*.txt' ].map { | e | 
  File.basename( e ).split(".").first 
}
