Figure 3-11. XML document without any formatting What s the problem Well, there is no problem as far as the document being well formed. It does follow all the rules of XML grammar. However, the document lacks proper formatting. Such documents are difficult for the human eye to read. Fortunately, the XmlTextWriter class provides several formatting options that help you create well-formatted documents. To see how these formatting options work, you need to modify the previous application so it looks like the one shown in Figure 3-12.

The application has a check box that toggles whether the document will be formatted. You can specify the indention as well as the indent character (space or tab). The code in the Click event handler of the Export Data button needs to be modified as shown in Listing 3-7. Listing 3-7. Formatting XML Document While Writing private void button1_Click(object sender, EventArgs e) { SqlConnection cnn = new SqlConnection(textBox1.Text); SqlCommand cmd = new SqlCommand(); cmd.Connection = cnn; cmd.CommandText = "SELECT * FROM " + textBox2.Text; cnn.Open(); SqlDataReader reader = cmd.ExecuteReader(); XmlTextWriter writer = new XmlTextWriter(textBox3.Text, null); if(checkBox1.Checked) { writer.Formatting = Formatting.Indented; writer.Indentation = int.Parse(textBox4.Text); writer.IndentChar = (radioButton3.Checked ' ' : '\t'); } writer.WriteStartDocument(); writer.WriteComment("File exported on " + DateTime.Now); writer.WriteStartElement("table"); while (reader.Read()) { if (radioButton1.Checked) { writer.WriteStartElement("row"); for (int i = 0; i < reader.FieldCount; i++) { writer.WriteStartElement(reader.GetName(i)); writer.WriteString(reader.GetValue(i).ToString()); writer.WriteEndElement(); } writer.WriteEndElement(); } else { writer.WriteStartElement("row"); for (int i = 0; i < reader.FieldCount; i++)

{ writer.WriteAttributeString(reader.GetName(i), reader.GetValue(i).ToString()); } writer.WriteEndElement(); } } writer.WriteEndElement(); writer.Close(); reader.Close(); cnn.Close(); } Note the code marked in bold. The Formatting property of XmlTextWriter governs whether the document will be formatted. The Formatting property is an enumeration of type Formatting and contains two possible values: None and Indented. The Indentation property of XmlTextWriter specifies the number of indent characters to be written in the document. This property is useful only if Formatting is set to Indented. The IndentChar property holds the character to be used for indentation. Though you can specify any valid character for IndentChar, space and tab are commonly used. If you export the Customers table after making the preceding modifications, the resultant document should resemble Figure 3-13.
Figure 3-13. Well-formatted XML document Much better than the previous one, isn t it Though not covered by our application, you can also set the QuoteChar property to decide which character to use for enclosing attribute values. The default value for QuoteChar is the double-quote character.

Including Namespace Support
Recall from 2 and earlier discussion in this chapter that XML namespaces provide a method for uniquely qualifying element and attribute names used in an XML document by associating them with a namespace. When you create XML documents by using XmlTextWriter, you may need to include namespace support for the resultant document. That is what you are going to see in this section. Various methods of XmlTextWriter, such as WriteStartElement(), provide overloads that can be used to specify namespace and prefix information. To see how these overloads can be used, you need to modify the previous application so it looks like the one shown in Figure 3-14.
Figure 3-14. Namespace support in XmlTextWriter As you can see in Figure 3-14, there are text boxes for accepting the namespace URI and prefix from the user. The modified code that adds namespace support is shown in Listing 3-8. Listing 3-8. Namespace Support in XmlTextWriter private void button1_Click(object sender, EventArgs e) { SqlConnection cnn = new SqlConnection(textBox1.Text); SqlCommand cmd = new SqlCommand(); cmd.Connection = cnn; cmd.CommandText = "SELECT * FROM " + textBox2.Text; cnn.Open(); SqlDataReader reader = cmd.ExecuteReader();
