What i want to do is to get every item where key is admin, owner or billing and parse it as separate XML but so far i am able to parse only the hole XML. 我想做的是获取键为admin，所有者或账单的每个项目，并将其解析为单独的XML，但到目前为止，我仅能够解析漏洞XML。 I am trying to do 我正在尝试做
var admin = keys.Where(item => item.Attribute("key").Value == "admin").ToList();
to be able to get as string only this part of the XML: 才能仅将XML的以下部分作为字符串获取：
<item key="admin">
<dt_assoc>
<item key="country">US</item>
<item key="address3">Admin</item>
<item key="org_name">Example Inc.</item>
<item key="phone">+1.4165550123x1812</item>
<item key="last_name">Adams</item>
<item key="address2">Suite 100</item>
<item key="status">active</item>
<item key="state">CA</item>
<item key="email">adams@example.com</item>
<item key="city">Santa Clara</item>
<item key="postal_code">90210</item>
<item key="fax">+1.4165550125</item>
<item key="address1">32 Oak Street</item>
<item key="first_name">Adler</item>
</dt_assoc>
</item>

Have a look at following sample: 看看以下示例：
public class Program
{
public static void Main(string[] args)
{
var result = ExtractItem("admin");
Console.WriteLine(result);
Console.ReadKey();
}
public static string ExtractItem(string key)
{
var xmlString = Properties.Resource.xml; // your sample-xml-string here
var xmlDoc = XDocument.Parse(xmlString);
var element = xmlDoc.Descendants().FirstOrDefault(i => i.Attribute("key")?.Value == key);
return element?.ToString();
}
}
Prints following output: 打印以下输出：
<item key="admin">
<dt_assoc>
<item key="country">US</item>
<item key="address3">Admin</item>
<item key="org_name">Example Inc.</item>
<item key="phone">+1.4165550123x1812</item>
<item key="last_name">Adams</item>
<item key="address2">Suite 100</item>
<item key="status">active</item>
<item key="state">CA</item>
<item key="email">adams@example.com</item>
<item key="city">Santa Clara</item>
<item key="postal_code">90210</item>
<item key="fax">+1.4165550125</item>
<item key="address1">32 Oak Street</item>
<item key="first_name">Adler</item>
</dt_assoc>
</item>
