Adds an XML attribute to the selected blocks.

The blocks are selected based on usual screen selection properties. The Attribute extraction rule is useful for adding attributes to blocks and have it processed by a specific template.
This rule can add another XML attribute than the one specified in the rule parameters, when the mashup event property is filled (see mashup event property description).
Notes:

• This rule does not involve any specific template.
• If the attribute exists in a matching block, its value is replaced by the new one.
• This rule applies on any block.

Property Type Category Description
Attribute name String configuration Defines the name of the added attribute.
Attribute value String configuration Defines the value of the added attribute.
Comment String configuration Describes the object comment to include in the documentation report.
This property generally contains an explanation about the object.
Is active boolean configuration Defines whether the extraction rule is active.
Is final boolean configuration Defines if the extraction is final, i.e. whether pending extraction rules should try to match on the current extraction rule matching blocks.

If set to true, once the rule applies on a matching block, Convertigo doesn’t apply the following rules on this block. This can be used to prevent a block from being modified by other rules.
Mashup event String configuration Defines mashup events dispatched on click.
Mashup events can be of two types:

• Calling directly a transaction or a sequence in Convertigo,
• Launching an event in Mashup Composer.

Mashup event property allows to define a combination of one direct call to a Convertigo transaction or sequence and/or one launch of Mashup Composer event. Filling this property adds a mashup_event attribute to the block, containing the previous combination in a JSON syntax of one of the following formats:

• {"requestable":{"__transaction":"<transaction name>","__connector":"<connector name>"}} for a transaction call only,
• {"requestable":{"__sequence":"<sequence name>"}} for a sequence call only,
• {"event":"<event name>"} for a mashup event only,
• {"requestable":{"__transaction":"<transaction name>","__connector":"<connector name>"},"event":"<event name>"} for a transaction call and a mashup event,
• {"requestable":{"__sequence":"<sequence name>"},"event":"<event name>"} for a sequence call and a mashup event.

This mashup_event attribute and its content have to be handled by the XSL file applying at the end of the transaction to generate a real Convertigo call and/or Mashup Composer event on click on the displayed object.
Attributes int selection Defines the presentation attributes on which the rule applies, i.e. the rule applies on blocks matching these presentation attributes.
This property allows to configure the rule so that it applies only to parts of screens having specific attributes, for example green text on black background.
Presentation attributes to configure are :

• Color: Foreground color, Background color, to choose in a list of predefined colors or “not to take into account”.
• Decoration: bold, reverse, underlined, blink, for each decoration choose between “with the decoration”, “normal” (i.e. without the decoration), or “not to take into account”.
Screen zone XMLRectangle selection Defines the screen zone on which the rule applies, i.e. the rule applies on blocks completely contained in this screen area.
This property allows to configure the rule so that it applies only to areas of screens. All blocks found within the specified perimeter are matching this screen zone and can be processed by the rule.
The screen area is defined through four coordinates:

• x (area left corner),
• y (area upper corner),
• w (area width),
• h (area height).

All values are given in characters, with the upper left corner being (x=0, y=0).
-1 represents an undefined value: (x=-1, y=-1, w=-1, h=-1) is an undefined area representing the whole screen, i.e. all blocks, whatever their coordinates, are matching this screen zone and can be processed by the rule.
Type String selection Defines, using a regular expression, to which block types the rule applies.
For example, if set to:

• static, the rule applies to blocks of static type only.
• static | field, the rule applies to blocks of static or field type only.
• [^field], the rule applies to all but field type blocks.
