Hi,

I have a very large XML file in CruiseControl.NET 1.4 which I want to display its data to the browser.

In my XSL I have created the following:

<xsl:param name="pageNumber" select="0" />

When the user clicks on a "Next" link the page is refreshed with the addition of http://server/page.aspx?pageNumber=2

I have tried using msxml:script but it did not work because it complained about a javascript object: window.location.href. The error was it could not locate 'window' object or something like that.

ALL I want is when the page refreshes I get:

the value of pageNumber
http://server/page.aspx?pageNumber=2

populate this:
<xsl:param name="pageNumber" select="2" />

Very pretty straight forward but could not figure out how... I searched everywhere on the web and could not find anything.

Is there a solution you know of?

Thanks,
Yama

<xsl:stylesheet

xmlns:msxml="urn:schemas-microsoft-com:xslt"
xmlns:csharp="http://csharp"

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

<msxml:using namespace="System.Web"/>
<![CDATA[
public int GetPageNumber() {
int page = 0;
if(HttpContext.Current.Request.QueryString["pageNumber"] != null)
{
if(HttpContext.Current.Request.QueryString["pageNumber"].Length > 0)
{
page = Convert.ToInt32(HttpContext.Current.Request.QueryString["pageNumber"]);
}
}
return page;
}
]]>
</msxml:script>

<xsl:output method="html"/>
<xsl:template match="/">
<script type="text/javascript">
function foo()
{ return "your javascript here"; }
</script>
<style type="text/css">
body {
font:normal 88% verdana,arial,helvetica;
color:#000000;
}
table tr td, tr th {
font-size: 88%;
}
</stlye>
</xsl:template>
<xsl:template match="files">
<xsl:param name="recordsPerPage" select="10" />
<xsl:param name="pageNumber" select="number(csharp:GetPageNumber())" />
<xsl:param name="recordCount" select="count(//file)" />

<xsl:for-each select="//file">

<xsl:if test="position() &gt; $recordsPerPage * number($pageNumber) and
position() &lt;= number($recordsPerPage * number($pageNumber) +
$recordsPerPage)">

<!-- Display 50Mb XML -->
</xsl:if>
</xsl:for-each>


<span style="Z-INDEX: 101; LEFT: 261px; WIDTH: 501px;">
<xsl:if test="$pageNumber &gt; 0">
<xsl:element name="a">
<xsl:attribute name="href">?pagenumber=<xsl:value-of select="number($pageNumber)-1" />
</xsl:attribute>
&lt;&lt; Previous Page
</xsl:element>
&#160; &#160; &#160; &#160;
</xsl:if>
<xsl:if test="($recordCount - ((1+number($pageNumber)) * $recordsPerPage))&gt; 0">
<xsl:element name="a">
<xsl:attribute name="href">?pagenumber=<xsl:value-of select="number($pageNumber)+1" />
</xsl:attribute>
Next page &gt;&gt;
</xsl:element>
</xsl:if>
</span>

</xsl:template>


Hope this helps many others. Please let me know if anyone has questions.
