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, 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.
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/.
Question: how can I get the xml data? where am I wrong?
Thanks very much in advance.
