For people who want to produce *a specific JSON* and are willing to craft an XML document as appropriate to accomplish that, there's a library in commons that I wrote for our use in MarkMail:
http://developer.marklogic.com/svn/commons/trunk/json/ Or actually here's its new and proper home on github: http://github.com/marklogic/commons/tree/master/json/ http://github.com/marklogic/commons/raw/master/json/json.xqy The documentation is in xqdoc format within the file. The idea is you decide what JSON you want to produce, then you create an XML document following the simple rules of the library, and the library does the serialization from XML to JSON for you. MarkMail uses this for Ajax-based updating of page contents. Click on a facet, see the results update. The client can get the updated data in XML or JSON format. http://markmail.org/results.xqy?q=json&mode=xml http://markmail.org/results.xqy?q=json&mode=json -jh- On Apr 20, 2010, at 9:40 AM, Lee, David wrote: > Great Question.
