DESCRIPTION
The libexslt library is used to provide extensions to XSLT
functions. These extensions come from the EXSLT project
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-proces-
sor and linker. The supported extensions are:
COMMON
Namespace: http://exslt.org/common
See http://www.exslt.org/exsl/index.html for a descrip-
tion.
node-set() convert the given RTF into a node-
set.
object-type() returns the type of the given argu-
ment.
document Create multiple output documents.
See http://www.exslt.org/exsl/ele-
ments/document/index.html
MATH
Namespace: http://exslt.org/math
See http://www.exslt.org/math/index.html for a descrip-
tion.
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 argu-
ment.
power() returns the power base and power
arguments.
log() returns the natural log of the argu-
ment.
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 argu-
ment.
acos() returns the arc cosine of the argu-
ment.
atan() returns the arc tangent of the argu-
ment.
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 inter-
section 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 argu-
ment.
year() returns the year of a date as a num-
ber.
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 num-
ber.
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 speci-
fied 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 rep-
resents 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 ele-
ments, 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.
