DeltaNova Control Attributes Reference

Control attributes are placed on elements in the input XML to override DeltaNova's default comparison behaviour for specific nodes.

DeltaNova control attributes use the deltaxml namespace prefix (http://www.deltaxml.com/ns/well-formed-delta-v1). See the Namespace Index for more details.

The following table lists the current set of control attributes with a brief description and links to relevant documentation for each of them.

Not all compare and merhe allow the use of all of these attributes and may ignore or remove them when they are present in input documents.

Attribute Reference

Attribute	Description
@deltaxml:key	Used as an identifier on an element to inform the matching process.
@deltaxml:ordered="false"	Indicates that an element's children should be treated as an orderless set rather than an ordered list.
@deltaxml:ignore-changes	Indicates to post-comparison stages that identified changes should be ignored or resolved in some way.
@deltaxml:format="true"	Indicates that an element should be treated as inline formatting.
@deltaxml:mixed-content="true"	Informs the `NormalizeSpace` filter that an element's content model is mixed and that whitespace-only text nodes should be normalised, not removed.
@deltaxml:threshold="true"	Indicate whether to split an element based on the dissimilarity of the text.
@deltaxml:word-by-word="false"	Indicates that text nodes underneath the containing element should not be segmented into words prior to comparison.

Interaction with Pipeline Configuration

Control attributes on individual elements take precedence over pipeline-level default configuration for the same feature. For example, deltaxml:ignore="true" on an element bypasses any XPath-based ignore rules set in the DXP/DCP pipeline descriptor.
