Question

I just started using VS2010 and C#.

I’m trying to create an app which takes values from two textboxes and adds it to an existing xml file.

eg.

Text Box 1       Text Box 2
----------       ----------
A                B
C                D
E                F

I want the resultant xml file to be like this.

<root>
 <element>
 <Entry1>A</Entry1>
 <Entry2>B</Entry2>
 </element>
</root>

and so on…

Can this be done using C# ??

I’m unable to add the entries alternatively i.e. Entry1 should contain Text Box 1 line #1 and Entry2 Text Box 2 line #1.

Any help would be appreciated.

Thanks

You need to split the string retrieved from the text box based on the new line like this:

string[] lines = theText.Split(new string[] { Environment.NewLine }, StringSplitOptions.None);

Once you have values split for each text box, you can use System.xml.linq.xdocument class and loop through the values that you retrieve above.

Something like this:

XDocument srcTree = new XDocument(new XElement("Root",
    new XElement("entry1", "textbox value1")))

You can retrieve a xml document using a linq query or save it in an xml file using the Save method of XDocument

The below code will give you a string of XML data from the textboxes:

private string createXmlTags(TextBox textBox1, TextBox textBox2)
    {
        string strXml = string.Empty;
        string[] text1Val = textBox1.Text.Split(new string[] { Environment.NewLine }, StringSplitOptions.None);
        string[] text2Val = textBox2.Text.Split(new string[] { Environment.NewLine }, StringSplitOptions.None);
        int count = 1;
        IList<XElement> testt = new List<XElement>();
        
        for (int i = 0; i < text1Val.Count(); i++)
        {
            testt.Add(new XElement("Entry" + count, text1Val[i]));
            while (!String.IsNullOrEmpty(text2Val[i]))
            {
                count = count + 1;
                testt.Add(new XElement("Entry"+count,text2Val[i]));
                break;
            }
            count = count + 1;
        }
        foreach (var xElement in testt)
        {
            strXml += xElement.ToString();
        }
        return strXml;
    }

You can then insert the code to an existing xml document. Follow: How can I build XML in C#? and How to change XML Attribute
