Defines an IF...THEN...ELSE... conditional step looking for node(s) on a source.

The IfExistThenElse step is one of Convertigo Sequencer conditional steps. This step contains two child steps (Then and Else) which are executed depending on whether the source defined through the Source property exists or not:

• Then step and child steps are executed when the specified source exists.
• Else step and child steps are executed when the specified source does not exist.

Note: In Convertigo Studio, when an IfExistThenElse step is created in a sequence, it can be easily replaced by an IfExist, using the right-click menu on the step and choosing the option Change to > IfExist. The Source property remains the same and the steps present in the sub-steps are:

• steps present in the Then step are moved to the IfExist,
• steps present in the Else step are deleted.

Property Type Category Description
Comment String standard Describes the object comment to include in the documentation report.
This property generally contains an explanation about the object.
Is active boolean standard Defines whether the step is active.
Output boolean expert Defines whether the XML generated by this step should be appended to the resulting XML.
Set this property to true to add the step’s resulting XML to the sequence’s output XML (default value for steps generating XML). Set this property to false to prevent the steps’s XML result to appear in the sequence’s output XML.
Setting this property to false does not prevent the step’s generated XML from being used as a source by other steps.
Source XMLVector expert Defines the source to work on.
This property allows defining a list of nodes from a previous step on which current step performs tests.
A source is defined as a reference on a step previously existing in the parent sequence, associated with an XPath applied on the step’s result DOM. At runtime, the XPath is applied on the step’s current execution result XML and extracts a list of XML nodes resulting from this execution.
If the XPath doesn’t match or if the source is left blank, the step has no data to work on: the test fails.
