Re: [xwiki-devs] [xwiki-users] How to use ajax to get xml data returned from xwiki component

Hi, Thomas, Thanks for your response, I changed to this url: http://localhost:8080/xwikim/bin/get/Main/hellotest?outputSyntax=plain But I got responseXML containing this error: XML Parsing Error: no element found Location: http://localhost:8080/xwikim/bin/get/Main/hellotest?outputSyntax=plain Line Number 1, Column 1: then I changed to this velocity code: {{velocity output='false'}} $response.setContentType('application/xml') #set ($out = $response.getOutputStream()) $out.write("<?xml version='1.0' encoding='ISO-8859-1'?><test>test done</test>")

$out.flush() ##$out.close() {{/velocity}} Still the same parsing error, any clue?
