Here are a few snippets i use to exchange xml data from a client side js and cocoon2.
My scenario is: the client browser save an xml file on the server using the source
write transformer.
If you need to echo the file back to the browser, just serialize it again, eventually
after another transformation.
Hope this helps
--peppo
The client side js snippet:
{
...
reqxml=the-xml-you-want-to-transfer-to-cocoon
xmlhttp.open("POST", baseurl, false);
xmlhttp.send(reqxml);
var resxml=xmlhttp.responseXML;
//alert(resxml.xml);
if (!reqxml.documentElement) {
alert("could not
parse:\n\n"+xmlhttp.responseText);
return null;
}
// C2 error handling
try {
//check the response status
var buf=resxml.documentElement;
//alert(buf.childNodes.item(0).getAttribute("result"));
if
(buf.childNodes.item(0).getAttribute("result") != "success") {
var errmsg =
resxml.documentElement.text;
if (!ignoreErrors) alert("Non e stato
possibile salvare sul server il file.\n\n Il server ha risposto: "+errmsg);
return null;
}
else {
var
fname=resxml.documentElement.childNodes.item(0).getAttribute("src");
var pos=fname.indexOf('xdocs/');
fname=fname.slice(pos+6,fname.length-18);
alert("Una nuova versione del file
'"+fname+".xml' e stata salvata con successo sul server\n\nBuona continuazione!");
}
} catch (e) {
if (!ignoreErrors) alert("Server returned an
error, but was not understood by the editor.\n\n");
return null;
}
},
in the sitemap:
<map:match pattern="save">
<map:generate type="stream"/>
<map:transform type="write-source"/>
<map:serialize type="xml"/>
</map:match>
NB: the error handling is done on the basis of the xml generated by the source write
transformer used in the sitemap. See the docs for details.
