Select XML node value by attribute value with multiple levels

Question

I'm looking to get to value further in the XML code than I've seen examples for and with more attributes to consider.

The XML code is:

<?xml version="1.0"?>
<mysqldump xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <database name="Members">
        <table_structure name="Logins">
            <field Field="ID" Type="int(100)" Null="NO" Key="PRI" Extra="auto_increment" Comment="" />
            <field Field="Username" Type="text" Null="YES" Key="" Extra="" Comment="" />
            <field Field="Password" Type="text" Null="YES" Key="" Extra="" Comment="" />
            <key Table="Logins" Non_unique="0" Key_name="PRIMARY" Seq_in_index="1" Column_name="ID" Collation="A" Cardinality="1" Null="" Index_type="BTREE" Comment="" />
            <options Name="Logins" Engine="MyISAM" Version="10" Row_format="Dynamic" Rows="1" Avg_row_length="20" Data_length="40" Max_data_length="281474976710655" Index_length="2048" Data_free="20" Auto_increment="3" Create_time="2011-10-14 19:30:57" Update_time="2011-10-14 19:32:21" Collation="latin1_swedish_ci" Create_options="" Comment="" />
        </table_structure>
        <table_data name="Logins">
            <row>
                <field name="ID">1</field>
                <field name="Username">MyName</field>
                <field name="Password">MyPassowrd</field>
            </row>
            <row>
                <field name="ID">2</field>
                <field name="Username">MyName2</field>
                <field name="Password">MyPassowrd2</field>
            </row>
        </table_data>
    </database>
</mysqldump>

I'm trying to get to 1, MyName and Password to then enter them into an SQL database.

The issue I'm having is getting through the multiple levels:

<database name="Members">
    <table_data name="Logins">
        <row>
            <field name="ID">

With all the examples I'm finding only ones showing 1 or 2 levels.

This seems to work,

XElement xe = XElement.Load("C:\\PATH.xml");

int count = xe.Descendants("row").Count();

var items = xe.Descendants("field").Where(n => (string)n.Attribute("name") == "ID").ToList();

var items2 = xe.Descendants("field").Where(n => (string)n.Attribute("name") == "Username").ToList();

var items3 = xe.Descendants("field").Where(n => (string)n.Attribute("name") == "Password").ToList();

             for (int i = 0; i < count; i++)
             {
                 string res = items[i].Value.ToString();
                 string res2 = items2[i].Value.ToString();
                 string res3 = items3[i].Value.ToString();
             }

I've got an ID, but I now need all its other elements in its row.

That is,

if (id = 2)
{
    string name = username.value;
    string password = password.value;
}

where name will result in myName2 and password will be MyPassword2.

I don't want to put usernames and passwords in a list.

Any advice again?

Try with LINQ to XML.

Here you have a tutorial.
