(C# UWP/WinRT) Update an XML Attribute

Demonstrates how to update XML attributes.

The output XML is this:

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

Chilkat Universal Windows Platform (UWP) / WinRT Downloads Chilkat for the Universal Windows Platform (UWP)

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

bool success = 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".
success = xml.UpdateAttribute("b","pear");

// Because no attribute named "c" exists, UpdateAttribute
// will create it:
success = 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:
Debug.WriteLine(xml.GetXml());
