Increment the date

Question

I am not sure if it is something with xslt or xpath..but how do I increment a date by 1 day? For example, if the date is 2/16/2009 I want the date to become 2/17/2009.

Answer 1

if date is 02/16/2009 i want it to be incremented to 02/17/2009

Answer 2

http://www.dpawson.co.uk/xsl/rev2/dates.html contains the snippet

<xsl:function name="dp:date-add">
    <xsl:param name="date" as="xs:dateTime"/>
    <xsl:param name="days" as="xs:integer"/>
    <xsl:variable name="day" select="$date + ($one-day * $days)"/>
    <xsl:value-of select="format-dateTime($day,'[Y,*-2]-[M,2]-[D,2]')"/>
</xsl:function>

I have not tested this, but it claims to add the values of "days" to "date". I recall doing something similar, but my XSLT code was replaced long ago with template pages.
