Method Detail

date

public static String date(String datetimeIn)
The date:date function returns the date specified in the date/time string given as the argument. If no argument is given, then the current local date/time, as returned by date:date-time is used as a default argument. The date/time string that's returned must be a string in the format defined as the lexical representation of xs:dateTime in [3.2.7 dateTime] of [XML Schema Part 2: Datatypes]. If the argument is not in either of these formats, date:date returns an empty string (''). The date/time format is basically CCYY-MM-DDThh:mm:ss, although implementers should consult [XML Schema Part 2: Datatypes] and [ISO 8601] for details. The date is returned as a string with a lexical representation as defined for xs:date in [3.2.9 date] of [XML Schema Part 2: Datatypes]. The date format is basically CCYY-MM-DD, although implementers should consult [XML Schema Part 2: Datatypes] and [ISO 8601] for details. If no argument is given or the argument date/time specifies a time zone, then the date string format must include a time zone, either a Z to indicate Coordinated Universal Time or a + or - followed by the difference between the difference from UTC represented as hh:mm. If an argument is specified and it does not specify a time zone, then the date string format must not include a time zone.

dateTime

public static String dateTime()
The date:date-time function returns the current date and time as a date/time string. The date/time string that's returned must be a string in the format defined as the lexical representation of xs:dateTime in [3.2.7 dateTime] of [XML Schema Part 2: Datatypes]. The date/time format is basically CCYY-MM-DDThh:mm:ss, although implementers should consult [XML Schema Part 2: Datatypes] and [ISO 8601] for details. The date/time string format must include a time zone, either a Z to indicate Coordinated Universal Time or a + or - followed by the difference between the difference from UTC represented as hh:mm.

dayAbbreviation

public static String dayAbbreviation(String datetimeIn)
The date:day-abbreviation function returns the abbreviation of the day of the week of a date. If no argument is given, then the current local date/time, as returned by date:date-time is used the default argument. The date/time string specified as the argument is a left or 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: xs:dateTime (CCYY-MM-DDThh:mm:ss) xs:date (CCYY-MM-DD) If the date/time string is not in one of these formats, then the empty string ('') is returned. The result is a three-letter English day abbreviation: one of 'Sun', 'Mon', 'Tue', 'Wed', 'Thu' or 'Fri'. An implementation of this extension function in the EXSLT date namespace must conform to the behaviour described in this document.

dayInMonth

public static double dayInMonth(String datetimeIn)
The date:day-in-month function returns the day 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. The date/time string specified as the argument is a left or 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: xs:dateTime (CCYY-MM-DDThh:mm:ss) xs:date (CCYY-MM-DD) xs:gMonthDay (--MM-DD) xs:gDay (---DD) If the date/time string is not in one of these formats, then NaN is returned.

formatDate

public static String formatDate(String dateTime, String pattern)
The date:format-date function formats a date/time according to a pattern.

The first argument to date:format-date specifies the date/time to be formatted. It must be right or left-truncated date/time strings in one of the formats defined in [XML Schema Part 2: Datatypes]. The permitted formats are as follows:

The second argument is a string that gives the format pattern used to format the date. The format pattern must be in the syntax specified by the JDK 1.1 SimpleDateFormat class. The format pattern string is interpreted as described for the JDK 1.1 SimpleDateFormat class.

If the date/time format is right-truncated (i.e. in a format other than xs:time, or xs:dateTime) then any missing components are assumed to be as follows: if no month is specified, it is given a month of 01; if no day is specified, it is given a day of 01; if no time is specified, it is given a time of 00:00:00.

If the date/time format is left-truncated (i.e. xs:time, xs:gMonthDay, xs:gMonth or xs:gDay) and the format pattern has a token that uses a component that is missing from the date/time format used, then that token is replaced with an empty string ('') within the result.
