Hi, all, I followed this link: http://platform.xwiki.org/xwiki/bin/DevGuide/WritingComponents created a component which return xml data. Also I created a hellotest page inside the main space, and wrote the following velocity code: {{velocity output='false'}} $response.setContentType('application/xml') #set ($xmldata= $services.hello.getHelloXML()) $xmldata ##$context.setFinished(true) #set ($out = $response.getOutputStream()) $out.write($xmldata) $out.flush() {{/velocity}} I tested this code, I can get the xml data, now I use this ajax code to retrieve the xml data: var xmlhttp = GetXmlHttp(); if (xmlhttp) { xmlhttp.open("GET", url, true); xmlhttp.onreadystatechange = function () { if (xmlhttp.readyState == 4) { xmlResult = xmlhttp.responseText; ...... xmlhttp.send(null); } The url I used is: url = ' http://localhost:8080/xwikim/bin/view/Main/hellotest?outputSyntax=plain' when I debug with firefox to see the data inside xmlhttp either responseText or response, they were all a html document for the hellotest with the tags like body, div, etc, it is basically helltest.html file if you view the source code of this html page. I tried to change the output

true, the result is the same.

Question: how can I get the xml data? where am I wrong? Thanks very much in advance. Dave _______________________________________________ users mailing list users(a)xwiki.org http://lists.xwiki.org/mailman/listinfo/users

Hi, Thomas, Thanks for your response, I changed to this url: http://localhost:8080/xwikim/**bin/get/Main/hellotest?** outputSyntax=plain<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<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.close() {{/velocity}} Still the same parsing error, any clue?
