Regex file schemas are used for files made of regular expressions, such as log files. If you often need to connect to a regex file, you may want to centralize its connection and schema information in the Repository for easy reuse.
The New RegEx File wizard gathers both file connection and schema definitions in a four-step procedure.
This procedure requires some advanced knowledge on regular expression syntax.
To create a File Regex connection from scratch, expand the Metadata node in the Repository tree view, right-click File Regex and select Create file regex from the contextual menu to open the file metadata setup wizard.
To centralize a file connection and its schema you have defined in a Job, click the icon in the Basic settings view of the relevant component with its Property Type set to Built-in to open the file metadata setup wizard.
Then define the general properties and file schema in the wizard.
The new schema is displayed under the relevant File regex node in the Repository tree view. You can drop the defined metadata from the Repository onto the design workspace as a new component or onto an existing component to reuse the metadata. For further information about how to use the centralized metadata in a Job, see Using centralized metadata in a Job and Setting a repository schema in a Job.
To modify an existing file connection, right-click it from the Repository tree view, and select Edit file regex to open the file metadata setup wizard.
To add a new schema to an existing file connection, right-click the connection from the Repository tree view and select Retrieve Schema from the contextual menu.
To edit an existing file schema, right-click the schema from the Repository tree view and select Edit Schema from the contextual menu.
