Update an XML Attribute

See more XML Examples

Demonstrates how to update XML attributes.

The output XML is this:

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

Swift

func chilkatTest() {
    var success: Bool = false

    let xml = CkoXml()!

    success = xml.load(xmlData: "<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(attrName: "b", attrValue: "pear")

    // Because no attribute named "c" exists, UpdateAttribute
    // will create it:
    success = xml.updateAttribute(attrName: "c", attrValue: "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.add(toAttribute: "a", amount: 7)

    // Examine the result:
    print("\(xml.getXml()!)")
