YQL2DOM jQuery Plugin


 / Published in: jQuery
 

Convert YQL Jason results to a complete HTML Dom Note: unfortunatly the YQL JSON format is lossy Info: http://developer.yahoo.com/yql/guide/output-xml-json-conversion.html

Warning: this plugin doesn't work in the right manner! The problem is that there's no way to extract the attributes in the right order So for example:

just a test

may arbitrary become

testjust a
