Not sure what you mean by "will not work". If you state your
expectation and the result you actually got it will help identify what
went wrong.

If all of the code in your message is one long script, then the
ErrorCount variable you declared inside the first block (it... do..
end) has gone out of scope when the while statement is executed. Your
"while ErrorCount > 0" is really saying "while nil > 0" -- in other
words, the condition is always false.

If you have an array (like ErrFieldID) and you want to handle each
element in it, you probably want to iterate over the array like so:

err_field_id = get_xml_attrib_value(ie, "Error", "FieldID")
puts "Total claim errors #{err_field_id.size}"
err_field_id.each do |efid|
  puts "Correcting error: #{efid}"
  code_to_correct_error(efid)
end
