# KeyViewFilterDocument

A processor that uses KeyView to filter metadata and text from files.

The processor reads any files embedded in the FlowFile or referenced by the FlowFile, and passes these to KeyView. The metadata that is extracted by KeyView is added to the FlowFile as XML metadata. The text that is extracted by KeyView is appended to the content parts of the FlowFile.
