[xwiki-devs] How to use ajax to get xml data returned from xwiki component
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 to true, the result is the same. Question: how can I get the xml data? where am I wrong? Thanks very much in advance. Dave

That's because with this URL you get UI around your content (whatever is the syntax of your content), for this kind of use case you should use /get/ action instead of /view/.

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?

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>")
$out is an OutputStream, which doesn't have a write(String) method. You must give it a byte[] argument, so this works: #set ($s = "<?xml version='1.0' encoding='ISO-8859-1'?><test>test done</test>") $out.write($s.getBytes('ISO-8859-1'))
$out.flush() ##$out.close() {{/velocity}}
Still the same parsing error, any clue?
Thanks
Dave

Hi, Sergiu Dumitriu I tried your way like this: {{velocity output='false'}} $response.setContentType('application/xml') #set ($out = $response.getOutputStream()) #set ($s = "<?xml version='1.0' encoding='ISO-8859-1'?><test>test done</test>") $out.write($s.getBytes('ISO-8859-1')) {{/velocity}} But this still has the same parsing error: XML Parsing Error: no element found Location: http://localhost:8080/xwikim/bin/get/Geo/hellotest?outputSyntax=plain Line Number 1, Column 1: ^ I tried both from the ajax call and the link: http://localhost:8080/xwikim/bin/get/Main/hellotest?outputSyntax=plain and I got the same error. Any more clue? Thanks for your help. Dave On Sat, Mar 24, 2012 at 10:41 AM, Sergiu Dumitriu <[email protected]> wrote:

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:

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