This component is used for executing Python Script. The Python Script to be executed is specified using the Custom Property Sheet (CPS). This component executes the script on documents it receives as input and returns the result.

Icon

The component uses the document object to get the content and properties of the message. The result after executing of the script should be set back onto the document object.

Points to note

Input message content and properties can be accessed using document object.For example, 'document.getText()' returns input message content.To access a message property named 'TestProperty, 'document.getRecord().getProperty('TestProperty')' returns the value of the property.
Message properties can be set using 'setProperty' method.
Message properties which are set on input message also appear on output message unless they are changed in the script.For example, if a property named 'TestProperty' is present on input message then output message also contains the property unless it is changed in script provided.
Output message content can be set either by using 'setText(String value)' of document object or by specifying a return value(using 'print') in the script provided.If both present, return value is set as message content.

Attributes

Read Script from file?

If enabled, Script file path property appears where you can provide the location where the script file is saved.

Script File Path

Provide the complete path of the Python Script file (file should have .py extension) which you want to execute.
