EXSLT - date:week-in-year - Version 2

Version: 2
Status: implemented
User Page: index.html
XML Definition: date.week-in-year.xml
Function Package: date.week-in-year.zip

Function Syntax

number date:week-in-year(string?)

Template Syntax

<xsl:call-template name="date:week-in-year">
   <xsl:with-param name="date-time" select="string" />?
</xsl:call-template>

The date:week-in-year function returns the week of the year as a number. If no argument is given, then the current local date/time, as returned by date:date-time is used as the default argument. For the purposes of numbering, counting starts at 1 and weeks are considered to begin on a Sunday.

The date/time string specified as the argument is a right-truncated string in the format defined as the lexical representation of xs:dateTime in one of the formats defined in [XML Schema Part 2: Datatypes]. The permitted formats are as follows:

If the date/time string is not in one of these formats, then NaN is returned.

An implementation of this extension function in the EXSLT date namespace must conform to the behaviour described in this document.
