I'm trying to setup a top navigation bar on my Umbraco site using version 4.5.2. My site structure looks something like this

Content
     Home
     Resume
     Portfolio
           School
           Job 1
           Job 2
     Activities
     Projects
          Project 1
          Project 2
     Contact

Now I want a Top navigation bar that lists the following regardless of what page or page level the user is at.

Home| Resume | Portfolio | Activities | Projects | Contact

Most of the examples I've seen for navigation bars use a for-each statement like the one shown below.

<xsl:template match="/">

<ul>
<xsl:for-each select="$currentPage/ancestor-or-self::* [@level=$level]/* [@isDoc and string(umbracoNaviHide) != '1']">
  <li>
    <a href="{umbraco.library:NiceUrl(@id)}">
      <xsl:value-of select="@nodeName"/>
    </a>
  </li>
</xsl:for-each>
</ul>

</xsl:template>

I want to show *all* the level 1 documents (Home, Resume, Portfolio etc..). Yet if I set @level = 1 the XLST above shows the children of the level 1 ancestor of the current page. Which makes sense because that's what this XLST above should do:

<!-- Front the current page find the ancestor (or self) that has a level = 1
$currentPage/ancestor-or-self::* [@level=$level]

<!--Find all children of the level 1 ancestor that are a doc and not hidden-->
/* [@isDoc and string(umbracoNaviHide) != '1']

So what I found is that I can then find the parent of the level 1 ancestor of the current page, and then find all the children of that parent and then get all the level 1 documents.

<xsl:for-each select="$currentPage/ancestor-or-self::* [@level=$level]/parent::*/* [@isDoc and string(umbracoNaviHide) != '1']">

This, however, seems like an incredibly round about way of accessing all the level 1 documents. Can I instead write a XPath query based of the root of the entire site rather then the $currentPage?

Also, is there someway to download the XML for an entire site or at least a the current page so I can have a better understanding of what the XLST I'm writing is working on?
