Hello! I'd like to ask, whether xsltproc/libxslt will (or already does?) support for xpath function as defined here: http://www.w3.org/TR/xpath-functions/ (with the namespace http://www.w3.org/2005/xpath-functions). Thank you! Petr P.S. My version apparently doesn't: $ xsltproc --version Using libxml 20702, libxslt 10124 and libexslt 813 xsltproc was compiled against libxml 20702, libxslt 10124 and libexslt 813 libxslt 10124 was compiled against libxml 20702 libexslt 813 was compiled against libxml 20702 $ xsltproc --dumpextensions Registered XSLT Extensions -------------------------- Registered Extension Functions: {http://exslt.org/math}lowest {http://exslt.org/math}constant {http://exslt.org/math}power {http://exslt.org/math}log {http://exslt.org/math}asin {http://exslt.org/math}atan {http://exslt.org/math}exp {http://exslt.org/strings}concat {http://exslt.org/dates-and-times}leap-year {http://exslt.org/dates-and-times}month-name {http://icl.com/saxon}evaluate {http://icl.com/saxon}line-number {http://exslt.org/crypto}sha1 {http://exslt.org/sets}has-same-node {http://exslt.org/dates-and-times}add {http://exslt.org/dates-and-times}duration {http://exslt.org/dates-and-times}second-in-minute {http://exslt.org/dynamic}map {http://exslt.org/sets}difference {http://exslt.org/sets}distinct {http://exslt.org/sets}trailing {http://exslt.org/strings}tokenize {http://exslt.org/strings}encode-uri {http://exslt.org/strings}padding {http://exslt.org/dates-and-times}hour-in-day {http://icl.com/saxon}expression {http://exslt.org/math}max {http://exslt.org/math}atan2 {http://exslt.org/dates-and-times}month-abbreviation {http://exslt.org/crypto}md5 {http://exslt.org/crypto}rc4_encrypt {http://exslt.org/math}acos {http://exslt.org/sets}leading {http://exslt.org/strings}split {http://exslt.org/dates-and-times}day-abbreviation {http://exslt.org/dates-and-times}day-in-week {http://exslt.org/dynamic}evaluate {http://exslt.org/crypto}rc4_decrypt {http://exslt.org/math}min {http://exslt.org/math}highest {http://exslt.org/math}random {http://exslt.org/math}abs {http://exslt.org/strings}decode-uri {http://exslt.org/strings}align {http://exslt.org/dates-and-times}date {http://exslt.org/dates-and-times}date-time {http://exslt.org/dates-and-times}day-in-month {http://exslt.org/dates-and-times}day-of-week-in-month {http://exslt.org/dates-and-times}difference {http://exslt.org/math}cos {http://exslt.org/strings}replace {http://exslt.org/dates-and-times}day-name {http://exslt.org/dates-and-times}sum {http://exslt.org/dates-and-times}time {http://exslt.org/math}sin {http://exslt.org/dates-and-times}add-duration {http://exslt.org/dates-and-times}day-in-year {http://exslt.org/dates-and-times}week-in-year {http://xmlsoft.org/XSLT/}test {http://exslt.org/common}node-set {http://exslt.org/crypto}md4 {http://exslt.org/math}sqrt {http://exslt.org/dates-and-times}minute-in-hour {http://exslt.org/dates-and-times}month-in-year {http://exslt.org/dates-and-times}week-in-month {http://exslt.org/common}object-type {http://exslt.org/math}tan {http://exslt.org/sets}intersection {http://exslt.org/dates-and-times}seconds {http://exslt.org/dates-and-times}year {http://icl.com/saxon}eval Registered Extension Elements: {http://exslt.org/common}document {http://exslt.org/functions}result {http://xmlsoft.org/XSLT/}test Registered Extension Modules: http://exslt.org/functions http://icl.com/saxon http://xmlsoft.org/XSLT/
