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>

PowerBuilder

integer li_rc
integer li_Success
oleobject loo_Xml

li_Success = 0

loo_Xml = create oleobject
li_rc = loo_Xml.ConnectToNewObject("Chilkat.Xml")
if li_rc < 0 then
    destroy loo_Xml
    MessageBox("Error","Connecting to COM object failed")
    return
end if

li_Success = loo_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".
li_Success = loo_Xml.UpdateAttribute("b","pear")

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

// Examine the result:
Write-Debug loo_Xml.GetXml()


destroy loo_Xml
