And I am currently parsing it with following code:

XDocument xdoc = XDocument.Parse(XML);
    foreach (var descendant in xdoc.Descendants("records").Descendants("tablerow").Descendants("fieldlist"))
    {
        Lawyer tempLawyer = new Lawyer();
        foreach (var item in descendant.Elements())
        {
            switch (item.Attributes().First().Value)
            {
                case "name":
                    tempLawyer.name = item.Value;
                    break;
                case "street":
                    tempLawyer.street = item.Value;
                    break;
                case "zip_internal":
                    tempLawyer.zip = item.Value;
                    break;
                case "city_internal":
                    tempLawyer.city = item.Value;
                    break;
                case "phone":
                    tempLawyer.phone = item.Value;
                    break;
                case "fax":
                    tempLawyer.fax = item.Value;
                    break;
                case "web":
                    tempLawyer.web = item.Value;
                    break;
                case "latitude":
                    tempLawyer.lat = item.Value;
                    break;
                case "longitude":
                    tempLawyer.lng = item.Value;
                    break;
            }
        }
        list_Lawyer.Add(tempLawyer);
    }

It's working, but maybe there is a more simpler and faster way to achieve what I want. Maybe something like this:

var tempList = from element in 
xdoc.Descendants("records").Descendants("tablerow").Descendants("fieldlist").Elements()
       select new
       {
           name = (string)element.Attribute("name").Value,
           street = (string)element.Attribute("street").Value,
           zip = (string)element.Attribute("zip_internal").Value,
           city = (string)element.Attribute("city_internal").Value,
           phone = (string)element.Attribute("phone").Value,
           fax = (string)element.Attribute("fax").Value,
           web = (string)element.Attribute("web").Value,
           lat = (string)element.Attribute("latitude").Value,
           lng = (string)element.Attribute("longitude").Value,
       };

This code isn't working because the element's attribute is index="XXXXXX" and not XXXXXX, maybe someone can lead me into the right direction.

Join tables (1:n) with considering two records from the second table

I have two tables named letter and letter_person like this :

letter :

id | subject | body | time
==========================
 1 |  Hello  | null | ...
 .
 .
 .

and letter_person :

id | ref_person | ref_letter |   role
========================================
 1 |     1      |     1      |   sender
 2 |     2      |     1      |  receiver
 .
 .
 .

role is an enum field and can be sender or receiver

i want to select letters which are sent and received between two persons, i want something like this :

SELECT * FROM letter
JOIN letter_person ON letter_person.ref_letter = letter
WHERE
(letter_person.ref_person = 1 AND letter_person.role = 'sender') 
OR
(letter_person.ref_person = 2 AND letter_person.role = 'receiver')

But it's not exactly what i need.

This query selects all the letters which are sent by person1 + all the letters which are received by person2.

I need to get the conversation.

from element in xdoc.Descendants("fieldlist")
