We are working on a web site, which will facilitate the management of new external modules for BaseX. Users are expected to be able to upload new modules, search for existing modules and install them in local BaseX instances with a few clicks. This module will definitely be a good candidate for this web site.

Hi Andy,
Thanks for the quick solution! I imported the new module and was able to use the new function as follows:
xs:date(dates:parseDate($trial/completion_date)//value/text()) <= fn:current-date()
I verified the correctness for ~300 dates and the logic appears solid (for the kind of dates discussed below).
Any chance this could find its way into a BaseX release?
Best, Ron

Hi Ron,
I took a quick look at Joe's module and made the following changes:
Change datetime:format-date(..,"yyyy-MM-dd") to format-date(..,"[YYYY]-[MM]-[DD]") Change xdt:dayTimeDuration("P1D") -> xs:dayTimeDuration Change function in namespace local: to dates:
And saved as a gist [1]. Then in BaseX
import module namespace dates = "http://xqdev.com/dateparser" at "https://gist.githubusercontent.com/apb2006/ee0effdd53ca80daf4f1b3e99794ed89/...";
dates:parseDate("March 2017")
Returns
<date resolution="month"> <range> <start>2017-03-01</start> <end>2017-03-31</end> </range> <value>2017-03-01</value> </date>
Joe, I think all these changes are compatible with eXist too? [2]
Hope this helps. /Andy

Hi Joe,
Thanks for sharing that. I tried adapting your eXist port to BaseX and ran into issues with namespaces. At this point I don’t have the time or expertise to complete this but hopefully someone else will take up the challenge.
Best, Ron

Hi Ron,
You might find Ryan Grimm's date-parser library module useful if you have a larger range of date formats to handle:
https://github.com/marklogic-community/commons/blob/master/dates/date-parser...
While it was written with some MarkLogic-specific code, I adapted it for use with eXist (but haven't tested it with BaseX):

Hi Christian,
Much appreciated! I hardened the code (see below) since the dates (from CT.gov) occasionally also have the day of the month (e.g., “March 21, 2014”). Currently the function is dropping the day in such cases but I will look into capturing it in a future iteration.
Best, Ron
declare function local:to-date($string) { if (fn:matches($string, '[A-Za-z]+ [0-9]+') or fn:matches($string, '[A-Za-z]+ [0-9]+, [0-9]+')) then let $m := index-of($MONTHS, substring-before($string, ' ')) let $y := xs:integer(functx:substring-after-last($string, ' ')) return xs:date(string-join( ( format-number($y, '0000'), format-number($m, '00'), '01' ), '-') ) else () };

Hi Ron,
If your timestamp is available in IETF format, you can use fn:parse-ietf-date [1]. Otherwise, you’ll need to write a simple function by yourself:
declare variable $MONTHS := ( 'January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December' );
declare function local:to-date($string) { let $m := index-of($MONTHS, substring-before($string, ' ')) let $y := xs:integer(substring-after($string, ' ')) return xs:date(string-join(( format-number($y, '0000'), format-number($m, '00'), '01' ), '-')) }; local:to-date('March 2017')

Hi,
Is there a BaseX function for converting a string date in the form of “March 2017” to xs:date or xs:dateTime?
Thanks, Ron
