Wriggler

Wriggler was created to serve and the crawler for a search engine, moving its way through HTML and/or XML files and grabbing data based on pre determined tags then exporting it in a manipulatable format. Wriggler acts similarly to a spider, but was designed to be used with any number of local files, not as an actual web scraper.

Add this line to your application's Gemfile:

gem 'wriggler'

And then execute:

$ bundle

Or install it yourself as:

$ gem install wriggler

You only need to run one command to use Wriggler, run:

Wriggler.crawl(["array", "of", "HTML/XML", "tags"], directory)

Note: The directory in this should be the top level directory that your HTML/XML files are in. Wriggler will account for any nested directories within this directory that also contain HTML/XML files. At the end you will have a data structure that resembles this:

===============
Files Found: 2
===============
content = {
	tag1: ["Content", "Found", "in", "the", "First", "Opened", "File"], ["Content", "Found", "in", "the", "Second", "Opened", "File"]
	tag2: [], []
	tag3: ["Content", "Found", "in", "the", "First", "Opened", "File"], []
	tag4: [], ["Content", "Found", "in", "the", "Second", "Opened", "File"]
}

Where tag2 has no content found between both files, tag3 only found content in the first of the two files, tag4 only found content in the second of two files, and tag1 found content in both.
