XML Pipeline - Non-linear

Non-linear

Non-linear operations on pipelines may include:

• Conditionals — where a given transformation is executed if a condition is met while another transformation is executed otherwise
• Loops — where a transformation is executed on each node of a node set selected from a document or a transformation is executed until a condition evaluates to false
• Tees — where a document is fed to multiple transformations potentially happening in parallel
• Aggregations — where multiple documents are aggregated into a single document
• Exception Handling — where failures in processing can result an alternate pipeline being processed

Some standards also categorize transformation as macro (changes impacting an entire file) or micro (impacting only an element or attribute)
