Hi Andres,

You can do it by using c# coding and umbraco api within the xslt block. Here is an example about using c# and umbraco api within 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:visitTrack="urn:visitTrack"
        xmlns:umbraco.library="urn:umbraco.library" xmlns:Exslt.ExsltCommon="urn:Exslt.ExsltCommon" xmlns:Exslt.ExsltDatesAndTimes="urn:Exslt.ExsltDatesAndTimes" xmlns:Exslt.ExsltMath="urn:Exslt.ExsltMath" xmlns:Exslt.ExsltRegularExpressions="urn:Exslt.ExsltRegularExpressions" xmlns:Exslt.ExsltStrings="urn:Exslt.ExsltStrings" xmlns:Exslt.ExsltSets="urn:Exslt.ExsltSets" 
        exclude-result-prefixes="msxml umbraco.library Exslt.ExsltCommon Exslt.ExsltDatesAndTimes Exslt.ExsltMath Exslt.ExsltRegularExpressions Exslt.ExsltStrings Exslt.ExsltSets ">
<xsl:output method="xml" omit-xml-declaration="yes"/>
<xsl:param name="currentPage"/>
<xsl:template match="/">
<!-- start writing XSLT -->
<xsl:variable name="pageId" select="$currentPage/@id"/>
<xsl:value-of select="visitTrack:updateVisit($pageId)"/>
</xsl:template>
<msxml:script language="C#" implements-prefix="visitTrack">
    <msxml:assembly href="../bin/cms.dll" />
    <msxml:assembly href="../bin/umbraco.dll" />
    <msxml:assembly href="../bin/businesslogic.dll" />
    <msxml:using namespace="umbraco.BusinessLogic" />
    <msxml:using namespace="umbraco.cms.businesslogic.web" />
    <msxml:using namespace="umbraco.cms.businesslogic.web" />
    public static string updateVisit(int pageId)
    {
        User author = User.GetUser(0); 
        Document doc = new Document(pageId);
        int getCount=int.Parse(doc.getProperty("visit").Value.ToString()) + 1;
        doc.getProperty("visit").Value = getCount.ToString();
        doc.Publish(author);
        umbraco.library.UpdateDocumentCache(doc.Id);
        return getCount.ToString();
    }
  </msxml:script>
</xsl:stylesheet>

Hope this helps you

Pnima

thanks ! I'm using it !

I'm tying to apply for a quiz example but I couldn't fix this errorr....

System.Xml.Xsl.XslLoadException: Prefix 'visitTrack' is not defined. An error occurred at

I change visitTrack but what king of value or function can use ?

Changed all the "visitTrack" word? If you change the prefix from 

<msxml:script language="C#" implements-prefix="visitTrack">

then you have to change in 

xmlns:visitTrack="urn:visitTrack"

<xsl:value-of select="visitTrack:updateVisit($pageId)"/>

Hope this helps

look at this error too :

System.NullReferenceException: Object reference not set to an instance of an object.  

Please look my code to fix... 

If you have another answer or option to dev this code please let me know...

  <xsl:param name="currentPage"/>

  <xsl:template match="/">

    <!-- start writing XSLT -->

    <script type="text/javascript">

      iSend = $("#content input[name=quiz]:checked").val();

    </script>

    <xsl:variable name="tmp">

      <xsl:value-of select="isend"/>

    </xsl:variable>

    <xsl:variable name="myvar" select="number($tmp)"/>

    <xsl:value-of select="visitTrack:updateVisit($myvar)"/>

  </xsl:template>

  <msxml:script language="C#" implements-prefix="visitTrack">

    public static string updateVisit(int myvar)

    {

    Document doc = new Document(myvar);

    int getCount=int.Parse(doc.getProperty("visit").Value.ToString()) + 1;

    doc.getProperty("visit").Value = getCount.ToString();

    doc.Publish(author);

    umbraco.library.UpdateDocumentCache(doc.Id);

    return getCount.ToString();

    }

  </msxml:script>

</xsl:stylesheet>

is working on a reply...
