> -----------------
>
> Key: NUTCH-2248
> URL: https://issues.apache.org/jira/browse/NUTCH-2248
> Project: Nutch
> Issue Type: New Feature
> Components: parser, plugin
> Affects Versions: 1.12
> Reporter: Joseph Naegele
>
> This plugin allows for collecting {{uri}} links from CSS (stylesheets). This
> is useful for collecting parent stylesheets, fonts, and images needed to
> display web pages as intended.
> Parsed Outlinks do not have associated anchors, and no additional
> text/content is parsed from the stylesheet.
