The format-date() XPath Function Does Not Respect the Specified Locale
Problem
Formatting a date using another language code, as in this example:
title:before {
content: oxy_xpath('format-date(current-date(), "[Mn] [Y]", "ru", (), ())');
}results in an output like: [Language: en]september 2019, with
the date being formatted in English.Cause
The XPath expressions are evaluated using the Saxon HE processor. This processor does not support languages other than English.
Solution
As a solution, you can either switch to a more language-neutral format that avoids the
months names:
title:before{
content: oxy_xpath('format-date( current-date(), "[M] [Y]", "en", (), ())');
}or you can use a more complex XPath expression like
this:
title:before{
content: oxy_xpath("let $cm:= format-date(current-date(), '[MNn]') \
return concat( \
if ($cm= 'January') then 'JAN' else \
if ($cm= 'February') then 'FEB' else \
if ($cm= 'March') then 'MAR' else \
if ($cm= 'April') then 'APR' else \
if ($cm= 'May') then 'MAY' else \
if ($cm= 'June') then 'JUNE' else \
if ($cm= 'July') then 'JUL' else \
if ($cm= 'August') then 'AUG' else \
if ($cm= 'September') then 'SEPT' else \
if ($cm= 'October') then 'OCT' else \
if ($cm= 'November') then 'NOV' else '' \
, \
' ', \
format-date(current-date(), '[Y0001]') \
) ");
}Make sure the entire expression is rendered blue in the CSS editor. Replace the capitalized month names with the translation in the desired language.
