This scenario is a three-component Java Job created in Talend Studio .

This scenario:

  • uses the tFindRegexlibExpression component to connect to a web server and collects all regular expressions that have the word "email" in their description field,

  • uses the tMap component to reorganize the incoming data in the output flow and also to concatenate the two fields from the incoming data flow in one output column,

  • and finally writes all collected expressions in an csv file.

In this scenario we want tFindRegexlibExpressions to collect all regular expressions on the web server that have the word "email" in their Description field and those which rate is at least 1.

This Job can also be generated automatically from the Patterns > Regex node in the DQ Repository tree view. For further information about how to generate a Job to recuperate regular expressions, see the Talend Studio User Guide.
