Hi Nate, IIUC, in Sling, you need to use "html-generator". "htmlparser" refers to an AEM component.
See https://github.com/apache/sling/blob/trunk/contrib/extensions/rewriter/src/main/java/org/apache/sling/rewriter/impl/components/HtmlGeneratorFactory.java Regards, Justin On Tue, Jul 28, 2015 at 11:46 AM Nate Yolles <yol...@adobe.com> wrote: > Hello, > > I’m trying to add a link rewriter into the pipeline but I’m running into > some trouble.
