22 The libexslt library is used to provide extensions to XSLT functions.
23 These extensions come from the EXSLT project <http://www.exslt.org/>
24
26 To make use of these functions in XSLT the appropriate namespace must
27 be defined on the xsl:stylesheet element. To enable support for them
28 in libxslt(3) you must call the appropriate functions (listed in the
29 SYNOPSIS section) to register the extensions. The xslt-config shell
30 script can be used to obtain the necessary flags for the pre-processor
31 and linker. The supported extensions are:
32 COMMON
34 Namespace: http://exslt.org/common
35 See http://www.exslt.org/exsl/index.html for a description.
37 node-set() convert the given RTF into a node-set.
39 object-type() returns the type of the given argument.
41 document Create multiple output documents. See
43 http://www.exslt.org/exsl/elements/docu‐
44 ment/index.html
45 MATH
48 Namespace: http://exslt.org/math
49 See http://www.exslt.org/math/index.html for a description.
51 min() returns the minimum value of the given node-set
53 max() returns the maximum value of the given node-set
55 highest() returns the nodes in the node-set whose value is
57 the maximum value for the node-set.
58 lowest() returns the nodes in the node-set whose value is
60 the minimum value for the node-set.
61 constant() returns a number value of the given constant with
63 the given precision. The constants are PI, E,
64 SQRRT2, LN2, LN10, LOG2E, and SQRT1_2.
65 random() returns a random number between 0 and 1 inclu‐
67 sive.
68 abs() returns the absolute value of the argument.
70 sqrt() returns the square root of the argument.
72 power() returns the power base and power arguments.
74 log() returns the natural log of the argument.
76 sin() returns the sine of the argument.
78 cos() returns the cosine of the argument.
80 tan() returns the tangent of the argument.
82 asin() returns the arc sine of the argument.
84 acos() returns the arc cosine of the argument.
86 atan() returns the arc tangent of the argument.
88 atan2() returns the arc tangent function of the y/x argu‐
90 ments.
91 exp() returns the exponential function of the argument.
93 SETS
96 Namespace: http://exslt.org/sets
97 See http://www.exslt.org/set/index.html for a description.
99 difference() returns the difference between the two given
101 node-sets.
102 intersection() returns a node-set of the nodes within both given
104 node-sets.
105 distinct() returns a node-set of all nodes in the first
107 argument that are not in the seconds argument.
108 has-same-node() returns TRUE if there is an intersection between
110 the two given node-sets.
111 leading() returns a node-set of all nodes in the first
113 argument that precede the first node in the sec‐
114 ond argument.
115 trailing() returns a node-set of all nodes in the first
117 argument that follow the first node in the second
118 argument.
119 DATES and TIMES
122 Namespace: http://exslt.org/dates-and-times
123 See http://www.exslt.org/date/date.html for a description.
125 date-time() returns the current date and time as a date/time
127 string.
128 date() returns the date specified in the given date/time
130 string.
131 time() returns the time specified in the date/time
133 string given as the argument.
134 year() returns the year of a date as a number.
136 leap-year() returns true if the year given in a date is a
138 leap year.
139 month-in-year() returns the month of a date as a number.
141 month-name() returns the full name of the month of a date.
143 month-abbreviation() returns the abbreviation of the month of a date.
145 week-in-year() returns the week of the year as a number.
147 week-in-month() returns the week in a month of a date as a num‐
149 ber.
150 day-in-year() returns the month of a date as a number.
152 day-in-month() returns the day of a date as a number.
154 day-of-week-in-month()
156 returns the day-of-the-week in a month of a date
157 as a number.
158 day-in-week() returns the day of the week given in a date as a
160 number.
161 day-name() returns the full name of the day of the week of a
163 date.
164 day-abbreviation() returns the abbreviation of the day of the week
166 of a date.
167 hour-in-day() returns the hour of the day as a number.
169 minute-in-hour() returns the minute of the hour as a number.
171 second-in-minute() returns the second of the minute as a number.
173 seconds() returns the number of seconds specified by the
175 argument string.
176 add() returns the date/time resulting from adding a
178 duration to a date/time.
179 add-duration() returns the duration resulting from adding two
181 given durations together.
182 difference() returns the duration between the first date and
184 the second date.
