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>

Xbase++

LOCAL nSuccess
LOCAL oXml

nSuccess := 0

oXml := CreateObject("Chilkat.Xml")

nSuccess := oXml: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".
nSuccess := oXml:UpdateAttribute("b", "pear")

//  Because no attribute named "c" exists, UpdateAttribute
//  will create it:
nSuccess := oXml: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.
oXml:AddToAttribute("a", 7)

//  Examine the result:
? oXml:GetXml()

oXml:destroy()
