Single quotes with json::parse
Regarding the JSON module json::parse function, how do you cope with single quotes within the JSON data? I have tried escaping them with a backslash, but to no avail. In this example I think it's the single quote in "St. John's College" that is causing the problem: XQUERY let $database := 'lk' let $options := map { 'format': 'direct', 'escape': 'yes' } let $j := json:parse('{"roles":["poet","cleric"],"institutions":["St John's College","Cambridge University"],"characterId":"595051204300","homes":["Cheapside","London","Dea n Prior","Devon"],"image":"robert_herrick.jpg","DOB":"1591-08-24","attributes" :["People educated at Merchant Taylors' School","Northwood","Alumni of St John's College","Cambridge","Alumni of Trinity Hall","Cambridge","English poets","People from the City of London","People educated at Westminster School","London","English male poets"],"DOD":"1674-10-08","nationality":"British","givenName":"Robert","fam ilyName":"Herrick"}', $options) return db:add($database, $j, 'characters/c_595051204300_Robert_Herrick.xml') Stopped at ., 3/78: [XPST0003] Expecting closing bracket: json:parse. at /usr/local/lib/basex-api/src/main/perl/BaseXClient.pm line 58.

Hi Thomas, This problem is a general one when working with quotes; see: 'It is called "St. John's College"!' One solution is to go with the XQuery 3.1 string constructor [1] ``[It is called "St. John's College"!]`` Cheers, Christian [1] http://docs.basex.org/wiki/XQuery_3.1#String_Constructor On Thu, Aug 10, 2017 at 2:41 PM, Thomas Daly <letterbox@daladi.com> wrote:

I have tried escaping them with a backslash, but to no avail. In this example I think it’s the single quote in “St. John’s College” that is causing the problem:
XQUERY let $database := 'lk'
let $options := map { 'format': 'direct', 'escape': 'yes' }
let $j := json:parse('{"roles":["poet","cleric"],"institutions":["St John's College","Cambridge University"],"characterId":"595051204300","homes":["Cheapside","London","Dean Prior","Devon"],"image":"robert_herrick.jpg","DOB":"1591-08-24","attributes":["People educated at Merchant Taylors' School","Northwood","Alumni of St John's College","Cambridge","Alumni of Trinity Hall","Cambridge","English poets","People from the City of London","People educated at Westminster School","London","English male poets"],"DOD":"1674-10-08","nationality":"British","givenName":"Robert","familyName":"Herrick"}', $options)
return db:add($database, $j, 'characters/c_595051204300_Robert_Herrick.xml')

Just to make sure: Have you also escaped Merchant Taylors' School at the same time? I've successfully tried ' to escape the apostrophe. On 10.08.2017 14:41, Thomas Daly wrote:

Hello, Yes, I did escape all of them but got the same error. I have tried Christian's solution which solves the problem, and good to know about ' too.
