I am working in Umbraco 4.0.3 and using the PDCalendar package.  We have event items as document types and those are getting displayed in a calendar using the PDCTableCalendar.xslt file. 

The part of the code in that file that displays the event items in the calendar is as follows:

<xsl:template name="createOneCell">
    <xsl:param name="cell"/>
    <td height="50"><div id="calendar-day"><xsl:value-of select="date:dayinmonth($cell/@date)"/></div><br/>
        <xsl:for-each select="$cell/event">
            <div id="smalltext">
      <a href="{umbraco.library:NiceUrl(@id)}">
               <xsl:value-of select="umbraco.library:GetXmlNodeById(@id)/@nodeName"/>
                   </a>
      </div>
        </xsl:for-each>
    </td>
</xsl:template>

What I am trying to do here is to add a conditional that will limit the type of events that get displayed.  Within the Event Item document type, I have an EventType field where you can choose from Statewide, Regional and County events.  I want this particular calendar I'm setting up to only display the Regional events.  Can anyone tell me how to code this?

I'm thinking I need to add the following:

[string(data [@alias='eventType']) = 'Regional Event']

on the for-each line, or to add another line with the following:

<xsl:if test="@eventType='County Event'">
</xsl:if>

just to the inside of the for-each section, but everything I've tried is resulting in errors because I don't know the proper XSLT syntax to do this.  I'm trying to learn on the fly.  If I can get this for Regional Events, I'll use the same technique for the Statewide and County events calendars I'm also trying to set up.
