I need to write to an xml file using java

[eSlain]

\[code\]<script type="text/javascript" charset="utf-8">function init() { scheduler.config.multi_day = true; scheduler.config.details_on_dblclick=true; scheduler.config.details_on_create=true; scheduler.attachEvent("onEventSave",function(id,data){ var p=data.text; return false; }) } </script>\[/code\]I am developing a calendar-like application. By using this application, a user can add events to the calendar. At the time of saving event, the data should also be write to an XML file with event ID and content. I need to write the value in variable \[code\]p\[/code\] to an XML file using Javascript. How can I do that? Please help, I am completely new to this.
