Hi Alexadar,

I've just uploaded a new version which should make this easier for you as it now automatically registers the library as an XSLT extension.  Go download it and then try the following sample XSLT:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xsl:stylesheet [
  <!ENTITY nbsp "&#x00A0;">
]>
<xsl:stylesheet
  version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:msxml="urn:schemas-microsoft-com:xslt"
  xmlns:umbraco.library="urn:umbraco.library"
  xmlns:Exslt.ExsltCommon="urn:Exslt.ExsltCommon"
  xmlns:ViewCount="urn:ViewCount"
  exclude-result-prefixes="msxml umbraco.library Exslt.ExsltCommon ViewCount">

  <xsl:output method="xml" omit-xml-declaration="yes"/>

  <xsl:param name="currentPage"/>

  <xsl:template match="/">
    <ul>
      <xsl:for-each select="$currentPage//* [@isDoc ]">
        <xsl:sort select="ViewCount:GetViews(number(@id))//@count" order="descending"/>
        <xsl:variable name="counter" select="ViewCount:GetViews(number(@id))" />

        <li>
          Node: <xsl:value-of select="$counter//@nodeId" /><br />
          Count: <xsl:value-of select="$counter//@count" /><br />
          Last Viewed: <xsl:value-of select="$counter//@lastViewed" /><br />
          Category: <xsl:value-of select="$counter//@category" /><br />
          hide Counter: <xsl:value-of select="$counter//@hideCounter" /><br />
          enable History: <xsl:value-of select="$counter//@enableHistory" />
        </li>
      </xsl:for-each>
    </ul>
  </xsl:template>

</xsl:stylesheet>

Note that the ordering may not be quite what you expect if you try for the entire tree; if you filter for all products under a common parent for example, you may have better results.

I'll be posting a blog entry about the functions available in the library in the next day or so when I have more time.  But for now, try these:

• ViewCount:GetViews(int nodeId, string category)

  ViewCount:GetViews(int nodeId, string category, bool increment)

  ViewCount:Increment(int nodeId, string category)

  ViewCount:Reset(int nodeId, string category)

  (int) ViewCount:GetViewCount(int nodeId, string category, bool increment)

Increment increments the view count for a node only without returning any results; Reset resets the viewcount back to 0.

GetViewCount just returns the actual count by itself.
