Chilkat2-Python

import chilkat2

success = False

xml = chilkat2.Xml()

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:
print(xml.GetXml())
