void exsltCommonRegister(void);
void exsltDateRegister(void);
void exsltDynRegister(void);
void exsltFuncRegister(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
inclusive.
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
arguments.
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
number.
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
containing one token from the string.
padding() returns a string padded to a certain length.
align() returns a string aligned within another string.
concat() returns the concatenation of the string values of
the nodes in that node set.
FUNCTIONS
Namespace: http://exslt.org/functions
See http://www.exslt.org/func/index.html for a description.
function declares an extension function.
result returns the result of an extension function
declared in function().
