Question

I need to Convert a CSV into an XML document. The examples I have seen so far, all show how to do this with a fixed number of columns in the CSV.

I have this so far, using LINQ:

String[] File = File.ReadAllLines(@"C:\text.csv");

        String xml = "";

        XElement top = new XElement("TopElement",

        from items in File

        let fields = items.Split(';')

        select new XElement("Item",

        new XElement("Column1", fields[0]),

        new XElement("Column2", fields[1]),

        new XElement("Column3", fields[2]),

        new XElement("Column4", fields[3]),

        new XElement("Column5", fields[4])

        )

        );

        File.WriteAllText(@"C:\xmlout.xml", xml + top.ToString());

This is for a fixed amount of columns, but my .CSV has a different number of columns on each line.

How would you fit some sort of loop into this, depending on how many words (columns) there are in each line of the .CSV?

Thnx

Answer 1

var lines = File.ReadAllLines(@"C:\text.csv");

var xml = new XElement("TopElement",
   lines.Select(line => new XElement("Item",
      line.Split(';')
          .Select((column, index) => new XElement("Column" + index, column)))));

xml.Save(@"C:\xmlout.xml");

Input:

A;B;C
D;E;F
G;H

Output:

<TopElement>
  <Item>
    <Column0>A</Column0>
    <Column1>B</Column1>
    <Column2>C</Column2>
  </Item>
  <Item>
    <Column0>D</Column0>
    <Column1>E</Column1>
    <Column2>F</Column2>
  </Item>
  <Item>
    <Column0>G</Column0>
    <Column1>H</Column1>
  </Item>
</TopElement>
