Adding, Modifying, or Deleting Data

You can add, modify, or delete data in the XML document using any of the following C$XML op-codes:

• CXML-SET-DATA
• CXML-MODIFY-ATTRIBUTE
• CXML-ADD-CHILD
• CXML-ADD-SIBLING
• CXML-ADD-ATTRIBUTE
• CXML-ADD-COMMENT
• CXML-APPEND-COMMENT (useful for documenting why you modified an XML document)
• CXML-DELETE-ATTRIBUTE
• CXML-DELETE-ELEMENT
• CXML-DELETE-COMMENT

For the majority of these op-codes, you must pass the element handle as a parameter as well as the new value of that element or attribute. Other parameters may apply as well. See Library Routines for more details.
