How to export excel data using XMLMap and EPPlus

I was wondering if someone can assist me in achieving the C# code below in either EPPlus or OpenOffice XML:
Microsoft.Office.Interop.Excel.Application app = new Microsoft.Office.Interop.Excel.Application();
string excelFileName = "Sample.xlsx";
string currentDirectory = Directory.GetCurrentDirectory();
string excelFilePath = System.IO.Path.Combine(currentDirectory, excelFileName);
app.Workbooks.Open(excelFilePath,
Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing);
string xmlContent = string.Empty;
// Use the map (XSD inside the Excel file)
app.ActiveWorkbook.XmlMaps[1].ExportXml(out xmlContent);
app.Workbooks.Close();
Using Microsoft.Office.Interop.Excel.Application requires installation of Microsoft Office on the server. Is there any way around this other than installing Microsoft Engine?. Basically how to read XMLMap without office.Interop?
Thank you

ERROR with åäö using Word.Interop: Find Replace c#.Net

I have a word document which I pass to a function that super script everything between two "£"'s. The problem is that if I don't have enabled English setting on my computer there will display a error (in swedish) complaining about the matching. I guess it has something to do with this particular line doc.Find.Text = "£([A-Z]{1,5})£"; since the document also contains letter å,ä and ö. However I can't get it to work no matter what I try, I'm really stuck. I'm not an Interop expert so if anyone could help me out I would appreciate it a lot!
public void SuperScript(Word.Range doc)
{
doc.Find.Replacement.Font.Superscript = 1;
doc.Find.MatchWildcards = true;
doc.Find.Text = "£([0-9]{1,5})£";
doc.Find.Replacement.Text = #"\1";
doc.Find.Execute(Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Word.WdReplace.wdReplaceAll, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
doc.Find.Text = "£([A-Z]{1,5})£";
doc.Find.Replacement.Text = #"\1";
doc.Find.Execute(Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Word.WdReplace.wdReplaceAll, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
doc.Find.Text = "£([a-z]{1,5})£";
doc.Find.Replacement.Text = #"\1";
doc.Find.Execute(Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Word.WdReplace.wdReplaceAll, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
}

I'm just guessing... Hope this is an answer for you...
You could do Something like that "£(\w[^0-9]{1,5})£" or "£(\D{1,5})£ excluding numbers. If you don't care about the type of characters returned, you could just do "£(.{1,5})£"

Excel not Visible

I am opening an existing Excel file with following process:
Microsoft.Office.Interop.Excel.Application excel = new Microsoft.Office.Interop.Excel.Application();
excel.Visible = true;
Workbook w = excel.Workbooks.Open(#"E:\ishu\Test.xlsx"
, Type.Missing,
true, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing,
Type.Missing);
Worksheet ws = (Worksheet)w.Worksheets[1];
Microsoft.Office.Interop.Excel.Range xlRange = ws.UsedRange;
excel.Visible = true;
Excel process gets started in task manager but no Excel window get visible.

This probably isn't the answer you are looking for, but my application uses
System.Diagnostics.Process.Start(ExcelFileToOpen);
The above is run only when the Excel file exists.

Why am I getting Show method of Dialog class failed in c# when using the xlDialogPrint.show method?

I am trying to print a Microsoft Excel document in C# using visual studio and I get a Show method of Dialog class failed exception every time I attempt to execute this piece of code:
bool userDidntCancel =
ExcelApp.Dialogs[Excel.XlBuiltInDialog.xlDialogPrint].Show(
Type.Missing, Type.Missing, Type.Missing, Type.Missing,Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
Here is the full code I'm using:
Excel.Application ExcelApp = new Excel.Application();
Excel.Workbook wb = ExcelApp.Workbooks.Open(
PATH,
Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing);
Excel.Worksheet ws = (Excel.Worksheet)wb.Worksheets[1];
try
{
bool userDidntCancel =
ExcelApp.Dialogs[Excel.XlBuiltInDialog.xlDialogPrint].Show(
Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
}
catch
{
ExcelApp.Quit();
File.Delete("Container Status.xls");
}
Is there something I'm missing?

Exporting excel sheet to xml spread sheet 2003

I'm trying to export an excel sheet into xml spread sheet 2003 in order to apply some xsl on the result xml file ,
so , i have tried to save the sheet i'm working on using XlFormat enum as follows :
Excel.Application app = new Excel.Application();
Excel.Workbook workbook;
Excel.Worksheet NwSheet;
workbook = app.Workbooks.Open(#"C:\file.xlsx",
Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing);
NwSheet = (Excel.Worksheet)workbook.Sheets.get_Item(1);
string outfile = #"c:\temp.xml";
NwSheet.SaveAs(outfile, Excel.XlFileFormat.xlXMLSpreadsheet, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
This code generated an xml file with the following problems :
1-cells of type date are generated as :
2011-10-10T00:00:00.000 , i want it to be 10/10/2011 exactly as it was in the excel sheet so how can i access to these cell's types in order to change them ??
2-numbers as 8.2 were generated as 8.1999999999999993 why did that happen and how can i get it just as is it in the excel sheet
i guess both are faces of the same problem , i just need the data as it appears in the excel sheet.
