XmlTextWriter.Formatting Property

Indicates how the output is formatted.

[Visual Basic]
Public Property Formatting As Formatting
[C#]
public Formatting Formatting {get; set;}
[C++]
public: __property Formatting get_Formatting();
public: __property void set_Formatting(Formatting);
[JScript]
public function get Formatting() : Formatting;
public function set Formatting(Formatting);

Property Value

One of the Formatting values. The default is Formatting.None (no special formatting).

Remarks

If the Indented option is set, child elements are indented using the Indentation and IndentChar properties. Only element content will be indented. The following C# code writes out HTML elements including mixed content:

XmlTextWriter w = new XmlTextWriter(Console.Out); 
 w.Formatting = Formatting.Indented; 
 w.WriteStartElement("ol"); 
 w.WriteStartElement("li"); 
 w.WriteString("The big "); // This means "li" now has a mixed content model. 
 w.WriteElementString("b", "E"); 
 w.WriteElementString("i", "lephant"); 
 w.WriteString(" walks slowly."); 
 w.WriteEndElement(); 
 w.WriteEndElement();
   

The above code produces the following output:

<ol> 
  <li>The big <b>E</b><i>lephant</i> walks slowly.</li> 
</ol>
   

When this is viewed in HTML no white space appears between the bold and italic elements. In fact, in this example, if indenting was added between these elements the word "Elephant" would be incorrectly broken.

Note   Writing any text content, including String.Empty puts that element into mixed content mode. Child elements do not inherit this "mixed" mode status. A child element of a "mixed" element will do indenting, unless it is also contains "mixed" content. Element content (http://www.w3.org/TR/1998/REC-xml-19980210#sec-element-content) and mixed content (http://www.w3.org/TR/1998/REC-xml-19980210#sec-mixed-content) are defined according to the XML 1.0 definitions of these terms.
