The Text Filter Actions pack installs the following Automator actions in the Library > Automator folder:

· Get URLs from Text — This action extracts URLs from the text passed to it by the previous action. Detected URLs include email addresses, which are returned as links using the mailto:// schema. To extract just specific types of URLs, follow this action with the Filer URLs action which is part of the default library of Automator actions.
· Get Dates from Text — This action extracts dates from the text passed to it by the previous action. The extracted dates are returned in UNIX format (YYYY-MM-DD HH:MM GMT), but will be automatically converted to AppleScript date records if the action is followed by the Run AppleScript action.

NOTE: If you create a service workflow that uses the presence of dates in selected text as its context, and want to retrieve the detected dates, place these actions at the beginning of the workflow.
