(C#) Update an XML Attribute

Demonstrates how to update XML attributes.

The output XML is this:

<abc b="pear" c="orange" a="130">Test</abc>

Download: Chilkat .NET Assemblies

Chilkat.Xml xml = new Chilkat.Xml();

xml.LoadXml("<abc a=\"123\" b=\"apple\">Test</abc>");

//  The UpdateAttribute and AddOrUpdateAttribute methods
//  are identical.  Both will replace the attribute's value if it
//  already exists, or insert a new attribute if it does not yet exist.

//  Change the value of attribute "b" to "pear".
xml.UpdateAttribute("b","pear");

//  Because no attribute named "c" exists, UpdateAttribute
//  will create it:
xml.UpdateAttribute("c","orange");

//  If an attribute's value is an integer, the AddToAttribute
//  method may be called to update it by adding an integer value.
//  For example, update the value of "a" to "130" by adding 7.
xml.AddToAttribute("a",7);

//  Examine the result:
textBox1.Text += xml.GetXml() + "\r\n";
