Retrieve MDX from pps dashboard deployed on Sharepoint Site Collection

Is there a way to retrieve the names and corresponding mdx queries of charts and reports deployed on a sharepoint site ?
i am using Shrepoint 2010

SharePoint Server 2010 uses the PPSAuthoringService web service instead of PmService. If you havent seen it yet, check out this post on the PerformancePoint Services team blog: http://blogs.msdn.com/b/performancepoint/archive/2010/09/13/using-the-ppsauthoringservice-web-service.aspx

The OLAP report's query is stored in the ReportView.CustomData property. Something like this should work (even though this example calls the web service from the API). Warning--I'm an amateur programmer.

2/4/11 -- Instead of querying the report's CustomData prop as shown below, you can just pass the report location to the GetMdx method.

static void Main(string[] args)
{
    string pathToAuthoringService = "http://<serverName>/_vti_bin/PPS/PPSAuthoringService.asmx";
    IBIMonitoringAuthoring service = BIMonitoringAuthoringServiceProxy.CreateInstance(pathToAuthoringService);

    string listUrl = "/BICenter/Lists/PerformancePoint Content/";
    FirstClassElementCollection fcos = service.GetListItems(listUrl);
    Dashboard dashboard = new Dashboard();

    foreach (FirstClassElement fco in fcos)
    {
        if (fco.ContentType == FCOContentType.PpsDashboard && fco.Name.Text == "Contoso Sales Management")
        {
            dashboard = fco as Dashboard;
        }
    }

    // Or if you know the ItemUrl, you can retrieve the dashboard directly.
    //RepositoryLocation dashboardLocation = new RepositoryLocation("/BICenter/Lists/PerformancePoint Content/32._000");
    //Dashboard dashboard = service.GetDashboard(dashboardLocation);

    List<RepositoryLocation> childLocations = dashboard.GetChildFCOLocations();
    foreach (RepositoryLocation location in childLocations)
    {
        if (location.ItemType == FirstClassObjectType.ReportView)
        {
            ReportView report = service.GetReportView(location);

            if (report.IsAnalyticReport())
            {
                Console.WriteLine(report.CustomData);
        }
    }
}

}
