使用C＃将XML数据导出到Excel

Question

XML:

<?xml version="1.0" encoding="ISO-8859-1"?> 
<IMPORT ExportDate="2016-03-02" Exercise="1" User="asa" Version="8.73" BusinessUnit="abc(1236)">

   <BusinessUnitAdmin>
    ...
    ...
    </BusinessUnitAdmin>
   <BusinessUnit>
    ..
    ..
    </BusinessUnit>
    <Exercise>
    ..
    ..
     </Exercise>
     <Exercise>
     ..
     ..
     </Exercise>
     <Contact>
     ..
     </Contact>
 </IMPORT>

I am trying to export this XML to Excel, while also maintaining the schema of XML. For this, I have tried converting the XML to Dataset and then exporting it to Excel. It works correctly if I remove the root element - IMPORT from the XML. However since it has ' BusinessUnit as attribute, its preventing to read "BusinessUnit" as element. For this, I am trying to read XML from second element - <BusinessUnitAdmin> ; but unable to do.

C# Code:

DataSet ds = new DataSet();
string path = "C:\\abc\\xyz.xml";
ds.ReadXml(path);                         //throws error
ExportDataSetToExcel(ds);

Error: "A column named 'BusinessUnit' already belongs to this DataTable: cannot set a nested table name to the same name."

I have tried using LINQ:

XDocument xdoc = XDocument.Load(path);
XElement import = xdoc.Element("IMPORT");
XElement contact = import.Element("Contact");
StringReader theReader = new StringReader(contact.ToString());
ds.ReadXml(theReader);

It works correctly, but this way, I have to manually read all elements.

I also tried reading elements using - var allElements = xdoc.Descendants() ; but unable to store specific elements in dataset.

Answer 1

For me, the problem isn't that you can't export your XML data into Excel.

The problem is actually that you can't convert your XML - which is in a tree-based hierarchical format - into a 2D array of values, ready to be exported to Excel.

I mean, if your XML contained three levels of hierarchy, how would you expect Excel to display this ?!

Anyway, let me answer the second part of your question.

If you can get your data in a regular 2-dimensional format, either as a DataSet or DataTable , then you can use my free C# class to write it to an .xlsx file using one line of code.

Export to Excel

Now, you just need to get your data into a usable format.

Over to you...!
