EXSLT - date:week-in-month - Implementer Page

Version: 3
Status: implemented
User Page: index.html
XML Definition: date.week-in-month.xml
Function Package: date.week-in-month.zip

Function Syntax

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

Template Syntax

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

The date:week-in-month function returns the week in a month of a date as a number. If no argument is given, then the current local date/time, as returned by date:date-time is used the default argument. For the purposes of numbering, the first day of the month is in week 1 and new weeks begin on a Monday (so the first and last weeks in a month will often have less than 7 days in them).

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.
