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>

B4X

Dim success As Boolean = False

Dim xml As ChilkatXml
xml.Initialize

success = xml.LoadXml("<abc a=" & Chr(34) & "123" & Chr(34) & " b=" & Chr(34) & "apple" & Chr(34) & ">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:
Log(xml.GetXml)
