<diff> Element

The <diff> element is an optional child of the <component> element. This element contains a list of directives that are used by the comparison engine to run comparisons on this component. If used, this element can only appear one time.

The <diff> element has one child element, <ignore>, which is required. This element specifies a directory path to ignore during comparison. You can use the <ignore> element one or more times.

A derived component automatically inherits all of the ignore directives declared by its base component. The component can also declare additional ignore directives in its own <diff> element. Inherited directives cannot be removed.

<ignore> Element

The <ignore> element is a child of the <diff> element and specifies a file name path pattern to ignore when using this component in a comparison. This element is typically for files and directories that are created by the installed application, such as log files. The configurable attributes of this element can reference component substitution variables.

The <ignore> element has one required attribute, path, which is a glob-style pattern that matches the file name paths to ignore, for example, /logs/*.log. This attribute can reference component-scoped substitution variables.
