I have a series of dates

<date>2008-12-03T04:00:00-06:00</date>
<date>2008-12-04T04:00:00-06:00</date>
<date>2008-12-05T04:00:00-06:00</date>

I am trying to build an input check box for the current week +1 (8 days starting with the current day) where if one of the <date>s falls within the current week, then the input check box is selected.

I have built the series of checkboxes, but I am having a difficult time determining when an input box should be 'checked'. What I have done so far:

<xsl:template name="operating_days">


  <xsl:param name="schedule"/>


  <xsl:variable name="date" select="current-dateTime()"/>

  <xsl:for-each select="0 to 7">
    <input type="checkbox" name="checkbox" value="checkbox">

       <xsl:if test="
                 day-from-dateTime(eb:date-add($date,.))
                   eq
                 day-from-dateTime($schedule//date)">
          <xsl:attribute name="checked">checked</xsl:attribute>
       </xsl:if>
    </input>
      <xsl:value-of select="value"/>
  </xsl:for-each>

</xsl:template>

This is not working because I cannot test over a sequence of items. Any ideas on how to determine if the current date equals one of the define <date>s?

I think you want

<xsl:variable name="date" select="current-date()" as="xs:date"/>
<xsl:variable name="oneDay" select="xs:dayTimeDuration('P1D')" as="xs:dayTimeDuration"/>
<xsl:variable name="scheduleDates" as="xs:date*" select="$schedule//date/xs:date(xs:dateTime(.))"/>
 then
test="($date + .*$oneDay) = $scheduleDates"
