Ruby parsing xml file with nokogiri sax parser

I have done some reading and I have been trying to get certain data from a large XML file. The data looks like this:

<Provider ID="0042100323">
    <Last_Name>LastName</Last_Name>
    <First_Name>FirstName</First_Name>
    <Mdl_Name>Middle</Mdl_Name>
    <Gndr>M</Gndr>
</Provider>

I would like to write the start_element to add all of these to a record array like so

0042100323, LastName, FirstName, Middle, M

def start_element name, attributes = []
    @@records << attributes[0][1] if name == "Provider"
end

How can I update my code to add the other tags to the array?
