An API for functionally updates to data represented in trees, such as XML trees, is provided. Functional updates can be implemented using an update combinator to search for matching nodes and apply an indicated function to those matching nodes. This API can be used in non-functional languages, such as procedural languages or scripting languages. Updates are performed without side effects since a shallow clone is created for at least a portion of a tree. Nodes of the tree can be streamed into memory so that only a portion of a large tree is present in memory at any time. Artificial intelligence can be used by the API to optimize performance under the circumstances, such as optimizing based on node type that is to be updated.
