I have written a small XSLT script to list out banner images. (see code below).

I have 2 root nodes, one called home, and one called banner.  Our designers want a rolling banner on every page, so figured I would stick the macro in the main template, but also to make it easier, I have put the banner folder, with all the images as a second root node, see image.

My question is, how to I target just that node in my xslt code?

<ul>
 <xsl:for-each select="Banner/BannerImage [@isDoc]">
        <xsl:choose>
           <xsl:when test="url != ''">
                <!-- check to see if the new browser check box was ticked -->
               <xsl:variable name="window">
                   <xsl:choose>
                       <xsl:when test="linkTarget = 1">
                           _blank
                     </xsl:when>
                        <xsl:otherwise>
                            _self
                      </xsl:otherwise>
                   </xsl:choose>
              </xsl:variable>
                <!-- did they provide an alt text, if not, use the value in the image name -->
              <xsl:variable name="alt">
                  <xsl:choose>
                        <xsl:when test="altText != ''">
                            <xsl:value-of select="altText"/>
                        </xsl:when>
                        <xsl:otherwise>
                            <xsl:value-of select="Name"/>
                        </xsl:otherwise>
                 </xsl:choose>
              </xsl:variable>
                <xsl:variable name="mediaImage" select="umbraco.library:GetMedia(bannerImage, false())" />
                <li>
                    <a href="{url}" target="$window">
                      <img src="{$mediaImage/umbracoFile}" alt="{$alt}" />
                    </a>
                </li>
            </xsl:when>
            <xsl:otherwise>
               <xsl:variable name="alt">
                  <xsl:choose>
                        <xsl:when test="altText != ''">
                            <xsl:value-of select="altText"/>
                        </xsl:when>
                        <xsl:otherwise>
                            <xsl:value-of select="Name"/>
                        </xsl:otherwise>
                 </xsl:choose>
              </xsl:variable>
                <xsl:variable name="mediaImage" select="umbraco.library:GetMedia(bannerImage, false())" />
                <li>
                 <img src="{$mediaImage/umbracoFile}" alt="{$alt}" />
                </li>
            </xsl:otherwise>
        </xsl:choose>
</xsl:for-each>
</ul>

FYI, the Banner folder has and alias Banner, and each Image node has an alias BannerImage.

Thank you for any advice.
