I'm wondering if there is a robust and graceful way using linq2xml to query an item deep within an xml hierarchy. For example:

<?xml version="1.0" encoding="utf-8" ?>
<data>
    <core id="01234">
        <field1>some data</field1>
        <field2>more data</field2>
        <metadata>
            <response>
              <status code="0">Success</status>
              <content>
                 <job>f1b5c3f8-e6b1-4ae4-905a-a7c5de3f13c6</job>
                 <id>id of the content</id>
              </content>
            </response>
        </metadata>
    </core>
</data>

With this xml how do I query the value of without using something like this:

var doc = XElement.Load("file.xml");
string id = (string)doc.Element("core")
    .Element("metadata")
    .Element("response")
    .Element("content")
    .Element("id");

I don't like the above approach because it is error prone (throws exception if any tag is missing in the hierarchy) and honestly ugly. Is there a more robust and graceful approach, perhaps using the sql-like syntax of linq?
