<para>The first XPath expression does not use namespaces. It would match
against payload such as this one:</para>
<programlisting>&lt;employees&gt;
&lt;employee&gt;
&lt;name&gt;Fred Jones&lt;/name&gt;
&lt;address location="home"&gt;
&lt;street&gt;900 Aurora Ave.&lt;/street&gt;
&lt;city&gt;Seattle&lt;/city&gt;
&lt;state&gt;WA&lt;/state&gt;
&lt;zip&gt;98115&lt;/zip&gt;
&lt;/address&gt;
&lt;address location="work"&gt;
&lt;street&gt;2011 152nd Avenue NE&lt;/street&gt;
&lt;city&gt;Redmond&lt;/city&gt;
&lt;state&gt;WA&lt;/state&gt;
&lt;zip&gt;98052&lt;/zip&gt;
&lt;/address&gt;
&lt;phone location="work"&gt;(425)555-5665&lt;/phone&gt;
&lt;phone location="home"&gt;(206)555-5555&lt;/phone&gt;
&lt;phone location="mobile"&gt;(206)555-4321&lt;/phone&gt;
&lt;/employee&gt;
&lt;/employees&gt;</programlisting>
<para>The second XPath expression does use namespaces. It would match
the following payload:</para>
<programlisting>&lt;xq:employees xmlns:xq="http://www.example.com/employees"&gt;
&lt;employee&gt;
&lt;name&gt;Fred Jones&lt;/name&gt;
&lt;address location="home"&gt;
&lt;street&gt;900 Aurora Ave.&lt;/street&gt;
&lt;city&gt;Seattle&lt;/city&gt;
&lt;state&gt;WA&lt;/state&gt;
&lt;zip&gt;98115&lt;/zip&gt;
&lt;/address&gt;
&lt;address location="work"&gt;
&lt;street&gt;2011 152nd Avenue NE&lt;/street&gt;
&lt;city&gt;Redmond&lt;/city&gt;
&lt;state&gt;WA&lt;/state&gt;
&lt;zip&gt;98052&lt;/zip&gt;
&lt;/address&gt;
&lt;phone location="work"&gt;(425)555-5665&lt;/phone&gt;
&lt;phone location="home"&gt;(206)555-5555&lt;/phone&gt;
&lt;phone location="mobile"&gt;(206)555-4321&lt;/phone&gt;
&lt;/employee&gt;
&lt;/xq:employees&gt;</programlisting>
<para>Note the different namespace used in the second example.</para>
