Parse HTML file, find file links, and add files to stream

[BlackxSnow]

Is there an existing solution to perform the titular process? I'm looking to recreate webpack's html-loader / HTMLWebpackPlugin functionality to only process and build files (media, in particular) that are used.

I'm currently attempting to filter the files before passing them to gulp-rev, but I haven't found any plugin to extract asset references from html / php files.
