DCP Schema Guide

This guide provides a short description of each element and attribute defined in the XML schema for the Document Comparator Pipeline (DCP). A fuller description of DCP, along with an example and an explanation of the main concepts can be found in the DCP User Guide.

Element Index

Element Detail

Elements are listed in document-tree order, top-level elements first, then alphabetically:

Element: documentComparator 1

The root element for defining the overrides to a DocumentComparator whose defaults are as described in the API documentation.

A Document Comparator instance with default settings is created if no child elements are present.

Element: calsColumnKeyingMode 36

Sets the column keying mode used to align table columns when the table processing is enabled.

In AUTO mode, the comparator will automatically handle the entire keying process. Only AUTO mode allows for user-defined keys in the input files. This is not possible in other modes.

Indexing starts from 1 and the maximum position is defined by the number of columns described by @cols attribute.

Element: advancedEntityReferenceUsage 86

For controlling some specialist use cases, where both the entity references and their replacement text are compared.

One use case where you might want to set this variable explicitly is: when you configure the comparator for standard 'round trip' lexical preservation, but the final output format cannot represent entity references. In this case, the REPLACE value can be used. This is an alternative to specifying a custom processing mode that performs round trip processing, except for entity references which are substituted for their values (i.e. their replacement text) prior to the comparison.
