Modifying XML file with Business Rule

[lblancher]

Hello,
  I am looking to update a file in the alfresco system, when another file is uploaded into a drop area, kind of like a historical list of files that pass through a space.  I am currently able to open and update the list file(in plain text format), but I would like to make the list file a xml file that I can apply a template(or style sheet) to.  After reading around the internet i found that Alfresco uses the Rhino Javascript engine from Mozilla.  I have there for looked at XML parsing JavaScript features for Firefox/Mozilla Browers. I have found two methods, but both result in exceptions generated in the alfresco.log file. 

First Method:
xmlDoc=document.implementation.createDocument("","",null);

Result:
TypeError: Cannot call method "createDocument" of undefined

Second Method:
var parser=new DOMParser();
var doc=parser.parseFromString(text,"text/xml");

Result:
ReferenceError: "DOMParser" is not defined.

I am using http://www.w3schools.com/dom/dom_parser.asp as my JavaScript reference for dealing with XML in JavaScript.

How can I resolve these errors? or how can I update a XML file from within  a Business Rule?

Thanks,
Lucas

Rhino uses JavaScript E4X to parse XML, you should therefore be able to do the following:

var book = new XML("<book><chapter>Title</chapter></book>");
var title = book.chapter;

You can learn more about the syntax and possibilities in the links below:

I Copy and Pasted the code that you put in your reply.  I now get the error 'ReferenceError: "XML" is not defined.'   Do i have to declare the XML type for use anywhere?

What version of Alfresco are you using? I'm not sure when we integrated/configured Rhino to use it's E4X support it maybe that you are using a version that doesn't support E4X!

Alternateivly, try using the latest nightly build or the code from SVN.

We don't have any confirmed dates for the 2.9 release as yet I'm afraid.
