yes, it is possible!!

here the code:

                var ns = "{http://schemas.infragistics.com/xaml/reports}";

                var document = XDocument.Load(path_igr);

                var reportDataSources = document.Descendants(ns + "SqlDataSource").Select(ds => new
                {
                    Name = ds.Attributes("Name").First().Value,
                    ConnectionStringKey = ds.Attributes("ConnectionName").First().Value,
                    QueryText = ds.Descendants(ns + "Query").Attributes("CommandText").First().Value,
                    Fields = ds.Descendants(ns + "SqlDataSource.Fields").Elements().Select(field =>
                        new
                        {
                            DataField = field.Attribute("DataField").Value,
                            Name = field.Attribute("Name").Value,
                            FieldTypeString = field.Attribute("FieldTypeString").Value
                        }),
                    Parameters = ds.Descendants(ns + "SqlDataSource.Parameters").Elements().Select(field => field.Attribute("Name").Value)
                });

                foreach (var dataSource in reportDataSources)
                {
                    MessageBox.Show(dataSource.QueryText, "SQL", MessageBoxButtons.OK, MessageBoxIcon.Information);
                }

Thanks!!
