    LDML for Node.js

    (UNICODE LOCALE DATA MARKUP LANGUAGE)

    Unicode's Common Locale Data Repository (CLDR) data is stored in XML files and uses a very custom inheritance scheme. With this module you can query the data and it will do the crazy inheritance for you.

    var ldml = require("ldml");
    ldml.data = __dirname + "/core/common";
     
    var en_US = ldml.cache.main.en_US;
    var path = "/ldml/dates/calendars/calendar[@type='buddhist']/dateTimeFormats/dateTimeFormatLength[@type='full']/dateTimeFormat/pattern";
    var found = en_US.query(path);
     
    if(found.length){
        console.log("found:", found[0]+"");
        console.log("at", ldml.cldrChain(found[0])+"");
        console.log("in", found[0].ownerDocument.locale);
    }
     
    /*
    found: <pattern>{1} 'at' {0}</pattern>
    at /ldml/dates/calendars/calendar[@type="generic"]/dateTimeFormats/dateTimeFormatLength[@type="full"]/dateTimeFormat/pattern
    in en
    */

    Notice how the end result came from calendar[@type="generic"] in the en.xml file.

    The full search route for this query was actually:

    en_US.xml → en.xml → root.xml (found an alias) → en_US.xml → en.xml
    

    Data files

    This repo does not include the CLDR data files. You will need to download and extract core.zip.

    ldml.data

    After downloading the data, you need to make sure the module knows where to find it. Set the data property to the location of the /common/ directory.

    ldml.cache

    For better performance, the XML document are cached on first load (lazy loaded).

    The cache object has a accessor for every ldml directory:

    ldml.cache.main
    ldml.cache.casing
    ldml.cache.collation
    ldml.cache.rbnf
    ldml.cache.segments

    Each will return an object with accessors for every locale found in that directory.

    ldml.open(directory, filename)

    Opens and parses an ldml file from the specified directory. Returns the XML doc.

    ldml.cldrChain(xmlElement)

    Returns an Array of information about the distinguished segments.

    You'll probably just want to call toString() on it.

    doc.query(xpath)

    Give it an xpath, it'll look up the data.
