LIBEXSLT(3)

LIBEXSLT 💖

okay so bestie, welcome to the libexslt page from the Library Functions Manual — she's the extension library for XSLT and she's lowkey iconic. let's get into it 🎀

---

✨ NAME ✨

libexslt — extension library for XSLT. that's it, that's the girl. 💅

---

🦋 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);

like, nine little register functions, all void, all taking no args, all serving cunt. ⭐

---

🌸 DESCRIPTION 🌸

so the libexslt library is literally there to provide extensions to XSLT functions. and where do these extensions come from? the EXSLT project, over at <http://www.exslt.org/> — she's the blueprint, the moment, the source. 👑

---

💜 USAGE 💜

bestie listen. to actually use these functions in your XSLT, you have to define the appropriate namespace on the xsl:stylesheet element. non-negotiable, it's giving paperwork. 🫶

and to enable support for them in libxslt(3), you gotta call the appropriate functions — the ones listed up in the SYNOPSIS section, you know the ones — to register the extensions. 📋

the xslt-config shell script is right there to get you the necessary flags for the pre-processor and linker, because we do not hand-roll flags in this house. ✨

so here's the roster of supported extensions, organized by vibe:

---

🧚 COMMON

Namespace: http://exslt.org/common

see http://www.exslt.org/exsl/index.html for a description. 💖

• node-set() — converts the given RTF into a node-set. glow-up complete.
• object-type() — returns the type of the given argument. she's nosy and we love her.
• document — creates multiple output documents. see http://www.exslt.org/exsl/elements/document/index.html for the whole saga.

---

🍓 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. (yes, SQRRT2 — that's how it's spelled, do not come for me, I don't make the rules 😭)
• 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.

---

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. (that's literally what it says, I'm just the messenger 🙈)
• 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.
