| # A small DSL for helping parsing documents using Nokogiri::XML::Reader. The | |
| # XML Reader is a good way to move a cursor through a (large) XML document fast, | |
| # but is not as cumbersome as writing a full SAX document handler. Read about | |
| # it here: http://nokogiri.org/Nokogiri/XML/Reader.html | |
| # | |
| # Just pass the reader in this parser and specificy the nodes that you are interested | |
| # in in a block. You can just parse every node or only look inside certain nodes. | |

Ideas are cheap. Make a prototype, sketch a CLI session, draw a wireframe. Discussions around concrete examples, not handy-waving abstractions. Don't say you did something, provide a URL that proves it.
Nothing is real until it's being used by a real user. This doesn't mean you make a prototype in the morning and blog about it in the evening. It means you find one person you believe your product will help and try to get them to use it.
