/ /// Editor that does Xml formatting and syntax highlighting. / /// Author: Ali Badereddin, Joseph Tignor / Description: Editor that does Xml formatting and syntax highlighting. Here is the code in the XmlEditor control that does the syntax highlighting: The Tokenize() public static method of the XmlTokenizer class does the job of splitting a string into XML tokens.Īn XmlToken object is a representation of an XML token with details about the exact text of that token, its location in the string and its type.

A “SpecialChar” is any character that is not a letter or a digit.An “Escape” is anything that starts with & and ends with (For example "e ).An “Attribute” is any letter or digit that falls after a.An “Element” is any letter or digit that falls between.A “Comment” is anything that starts with (or starts with ).A “Value” is anything between double quotes.I have identified the following token types (based on syntax highlighting behavior in Visual Studio 2008): To color the XML string, we have to split it into multiple tokens, then color each token based on its type. Here is how the control looks like when AllowXmlFormatting = true and ReadOnly = false (default values): The Text property sets or gets the text of the XMLeditor.

The ReadOnly property tells whether or not to allow the user to change the text. Use AllowXmlFormatting to enable or disable formatting on the XML content in the editor. The XmlEditor control currently has three public properties. Simply add the files ( XmlToken.cs, XmlTokenizer.cs, XmlEditor.cs, ) to your project, then drag and drop the XmlEditor control from the Toolbox into your Windows Form. I expect to add more features in the future like spacing, grouping, intellisense, etc… Usage For now, only syntax highlighting is implemented. If you have a Windows Forms application that involves XML editing or viewing, you can use this control to save yourself the effort of formatting the XML content.
