导出XML-> Excel

Question

I'm already generating an excel XML file (.xml) containing 2 worksheets.

issue #1:

the people downloading the XML file wouldn't know to open the file in Excel. (they'd complain.)

solution #1:

I rename the file to .XLS instead of .XML.

issue #2:

when opening the file in Excel i get the this error:

The file you are trying to open, ‘XXX.xls’ is in a different format than specified   by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file.

Solution #2:

Convert the XML file to XLS file somehow.

so here's where i turn to you...

Goal:

they need to be able to open the file by double-clicking it. i don't want to have to rebuild the excel file using some 3rd party library.

Ideas:

perhaps convert XML to xls using tools like the following:

http://npoi.codeplex.com/
http://excelpackage.codeplex.com/

I'd need some sample code of the simplest and LITEst way of achieving this.

any other ideas?

Answer 1

只是一个随机的想法：如果要生成供人们使用Excel打开的XML，为什么不首先生成XSL（或maby XSLX）呢？
