Solution 1

Try this:

C#

var result = xdoc.Descendants("hoststatus")
    .Select(x=>new
        {
            id = (int)x.Element("host_id"),
            host = (string)x.Element("display_name"),
            uptime = (DateTime)x.Element("status_update_time"),
            status = (string)x.Element("alias")
        });

Returns IEnumerable<int, string, DateTime, string> resultset:

id   host            uptime              status
2061 ZACN-PSPR-HVR13 2015-09-19 08:00:31 management_servers
2062 ZACN-PSPR-HVR14 2015-09-19 06:00:31 linux_servers2063 ZACN-PSPR-HVR15 2015-09-19 09:00:31 localhost

Note: your question is unclear... If you want to join data from both documents, you have to use members of document 1

C#

host_id = (int)x.Attribute("id")
// or/and
host_name = (string)x.Element("host_name")

To ba able to filter data, use Where condition.

If I understood your question correctly, you want to join the documents. If this is the case, consider the following:

C#

         string xml1 = @"<hostgroup id=""2080"">
    <instance_id>1</instance_id>
    <hostgroup_name>Avanade-Hypervisors</hostgroup_name>

        <host_name>ZACN-PSPR-HVR13</host_name>
      </host>
      <host id=""2062"">
        <host_name>ZACN-PSPR-HVR14</host_name>
      </host>
      <host id=""2063"">
        <host_name>ZACN-PSPR-HVR15</host_name>
      </host>
    </members>
</hostgroup>";

         string xml2 = @"<hoststatuslist>
 <hoststatus id=""49294"">
    <host_id>2061</host_id>
    <name>ZACN-VSPR-WAP02</name>

         System.Xml.Linq.XElement element1 = System.Xml.Linq.XElement.Parse(xml1);

         System.Xml.Linq.XElement element2 = System.Xml.Linq.XElement.Parse(xml2);

         var querya = from item1 in element1.Descendants("host")
                      join item2 in element2.Descendants("hoststatus")
                      on item1.Attribute("id").Value equals item2.Elements("host_id").First().Value
                      select new {
                         Host = item2.Elements("display_name").First().Value,
                         UpTime = item2.Elements("last_time_up").First().Value,
                         Alias = item2.Elements("alias").First().Value
                      };
