How to edit xml link?

Question

First a few words about my context:
I received a layout made on a CS3 version of InDesign. Now I am trying to create a procedure to automate the production of several pdf based on this layout. Manually the process would be to open the layout; edit the xml link with each xml source and create a corresponding pdf...
First issue:
In CS4 when I want to manually edit the xml link, the opened dialog prevent me (xml files are in gray) to select xml files, is it a well-known issue? How can I avoid it?
Second question:
How to edit the xml link from script?
Last question - applescript question - :
How to skip application dialogs? Like "This document miss some links, would you continue?"
If you'd be able to help me, thanks in advance!

Dear Loic_aigon
   Many thanks!
But I used what you said!.
But Still I'm facing the same problem [ not find : "image"]
Here the below tag I used..
<Figure id="f0020"><label>Figure 2 </label><caption>Dummy Figure </caption>
<image href="C:/Program %20Files/VUG/clouds.jpg"></image></Figure>
Program :
//============== Start =====================//
#include "E:/HariharaSudhan/XMDOM_TEST/xml_for_script-3.1/jsXMLParser/xmldom.js";
var myFile = File("E:/HariharaSudhan/XMDOM_TEST/xml/test.xml");
myFile.open("r");
var myXMLString = String(myFile.read());
var objDom = new XMLDoc(myXMLString, undefined);
var domTree = objDom.docNode;
$.writeln(domTree);
var myImage = domTree.getElements("image");
var myDoc = app.open(File("E:/HariharaSudhan/XMDOM_TEST/Indd/test.indd"), true);
$.writeln(myImage);
for(var i=0; i<myImage.length; i++)
$.writeln( myImage[i].name);
myImage[i].getAttribute("href").replace('file:///','');
  var myPage = doc.pages[0].duplicate(LocationOptions.AT_END);
  var myFrame = myPage.pageItems.item("image");
  myFrame.place(File(myImage[i].getAttribute("href").replace('file:///','')));
  app.pdfExportPreferences.pageRange = myPage.name;
  app.pdfExportPreferences.viewPDF  = false;
  myDoc.exportFile(ExportFormat.pdfType, File("E:/HariharaSudhan/XMDOM_TEST/PDF/" +(i+ 1)+".pdf"), undefined, undefined, undefined, undefined);
myDoc.close(SaveOptions.NO);
//===================== End ============================//
So please kindly see the attached xml file, and please send me the solutions.
Please this is my humble request.
Thanks & Regards
