LIBEXSLT(3)
NAME
libexslt - extension library for XSLT
SYNOPSIS
#include <libexslt/exslt.h> void exsltCommonRegister(void); void exsltDateRegister(void); void exsltDynRegister(void); void exsltFuncRegister(void); void exsltMathRegister(void); void exsltSetsRegister(void); void exsltStrRegister(void); void exsltRegisterAll(void); void exsltSaxonRegister(void);
DESCRIPTION
The libexslt library is used to provide extensions to XSLT functions.
These extensions come from the EXSLT project <http://www.exslt.org/>
USAGE
- To make use of these functions in XSLT the appropriate namespace must
be defined on the xsl:stylesheet element. To enable support for them
in libxslt(3) you must call the appropriate functions (listed in the
SYNOPSIS section) to register the extensions. The xslt-config shell
script can be used to obtain the necessary flags for the pre-processor
and linker. The supported extensions are:
- COMMON
- Namespace: http://exslt.org/common
- See http://www.exslt.org/exsl/index.html for a description.
- node-set() convert the given RTF into a node-set.
- object-type() returns the type of the given argument.
- document Create multiple output documents. See
http://www.exslt.org/exsl/elements/document/index.html
- MATH
- Namespace: http://exslt.org/math
- See http://www.exslt.org/math/index.html for a description.
- min() returns the minimum value of the given node-set
- max() returns the maximum value of the given node-set
- highest() returns the nodes in the node-set whose value is
the maximum value for the node-set.
- lowest() returns the nodes in the node-set whose value is
- the minimum value for the node-set.
- constant() returns a number value of the given constant with
- the given precision. The constants are PI, E, SQRRT2, LN2, LN10, LOG2E, and SQRT1_2.
- random() returns a random number between 0 and 1 inclu
- sive.
- abs() returns the absolute value of the argument.
- sqrt() returns the square root of the argument.
- power() returns the power base and power arguments.
- log() returns the natural log of the argument.
- sin() returns the sine of the argument.
- cos() returns the cosine of the argument.
- tan() returns the tangent of the argument.
- asin() returns the arc sine of the argument.
- acos() returns the arc cosine of the argument.
- atan() returns the arc tangent of the argument.
- atan2() returns the arc tangent function of the y/x argu
- ments.
- exp() returns the exponential function of the argument.
- SETS
- Namespace: http://exslt.org/sets
- See http://www.exslt.org/set/index.html for a description.
- difference() returns the difference between the two given
node-sets.
- intersection() returns a node-set of the nodes within both given
- node-sets.
- distinct() returns a node-set of all nodes in the first
- argument that are not in the seconds argument.
- has-same-node() returns TRUE if there is an intersection between
- the two given node-sets.
- leading() returns a node-set of all nodes in the first
- argument that precede the first node in the second argument.
- trailing() returns a node-set of all nodes in the first
- argument that follow the first node in the second argument.
- DATES and TIMES
- Namespace: http://exslt.org/dates-and-times
- See http://www.exslt.org/date/date.html for a description.
- date-time() returns the current date and time as a date/time
string.
- date() returns the date specified in the given date/time
- string.
- time() returns the time specified in the date/time
- string given as the argument.
- year() returns the year of a date as a number.
- leap-year() returns true if the year given in a date is a
- leap year.
- month-in-year() returns the month of a date as a number.
- month-name() returns the full name of the month of a date.
- month-abbreviation() returns the abbreviation of the month of a date.
- week-in-year() returns the week of the year as a number.
- week-in-month() returns the week in a month of a date as a num
- ber.
- day-in-year() returns the month of a date as a number.
- day-in-month() returns the day of a date as a number.
- day-of-week-in-month()
- returns the day-of-the-week in a month of a date as a number.
- day-in-week() returns the day of the week given in a date as a
- number.
- day-name() returns the full name of the day of the week of a
- date.
- day-abbreviation() returns the abbreviation of the day of the week
- of a date.
- hour-in-day() returns the hour of the day as a number.
- minute-in-hour() returns the minute of the hour as a number.
- second-in-minute() returns the second of the minute as a number.
- seconds() returns the number of seconds specified by the
- argument string.
- add() returns the date/time resulting from adding a
- duration to a date/time.
- add-duration() returns the duration resulting from adding two
- given durations together.
- difference() returns the duration between the first date and
- the second date.
- duration() returns a duration string that represents the
- given number of seconds since 1970-01-01T00:00:00.
- STRINGS
- Namespace: http://exslt.org/strings
- See http://www.exslt.org/str/index.html for a description.
- tokenize() returns a node set of token elements, each con
taining one token from the string.
- padding() returns a string padded to a certain length.
