Thanks, that was helpful.  I'm not quite where I want to be yet though.  I'm 
trying to create a sort of navigating scheme for an online course template, I 
was hoping to get an XPATH statement that could be used to get to any node 
regardless of it's type or position in the document.

All the nodes (except the document element) will have a "link" attribute 
with a webpage url (the example below is just dummy data, so all the link 
attributes are not unique)

Given the example XML data below, could I construct an XPATH that would give 
me (for example):

xmlCourse.selectSingleNode(".//node()[1]") =  the <courseInfo> node
xmlCourse.selectSingleNode(".//node()[2]") = the first <module> node
xmlCourse.selectSingleNode(".//node()[3]") = the first<lesson> under the 
first <module>
xmlCourse.selectSingleNode(".//node()[4]") = the first <topic> under the 
first <lesson>
xmlCourse.selectSingleNode(".//node()[5]") = the first <page> under the 
first <topic>
xmlCourse.selectSingleNode(".//node()[6]") = the SECOND <page>
xmlCourse.selectSingleNode(".//node()[7]") = the THIRD <page>

etc, etc...

Here is a simple example of the XML I'm trying to navigate:

<courseInfo courseName="Test Course" courseCode="009999">
  <module name="Module One" link="module1.html">
    <lesson name="M1 Lesson One" link="lesson1.html">
       <topic link="topic1.html" name="Module One Lesson One Topic One">
         <page link="link.html" name="M1L1T1Page1"/>
         <page link="link.html" name="M1L1T1Page2"/>
        <page link="link.html" name="M1L1T1 Page Three"/>
        <page link="link.html" name="M1L1T1Page Four"/>
    </topic>
   <topic name="Module One Lesson One Topic Two" link="topic2.html">
        <page name="Page One" link="link.html"/>
    </topic>
 </lesson>
  <lesson name="Module One Lesson Two" link="link.html">
    <topic name="TOPIC ONE IN THAT MODULE" link="link.html">
         <page name="one" link="link.html"/>
         <page name="two" link="link.html"/>
   </topic>
 </lesson>
</module>
</courseInfo>
