I tried using ActiveResource to parse a web service that was more like a HTML document and I kept getting a 404 error. Do I need to use an XML parser for this task instead of ActiveResource? My guess is that ActiveResource is only useful if you are consuming data from another Rails app and the XML data is easily translatable to a Rail...

I've found a few posts alluding to the fact that you can validate XHTML against its DTD using the nokogiri gem. Whilst I've managed to use it to parse XHTML successfully (looking for 'a' tags etc.), I'm struggling to validate documents. For me, this: doc = Nokogiri::XML(Net::HTTP.get(URI.parse("http://www.w3.org"))) puts doc.validate ...

Hello stackies. The following PiP search was built for a project that lets users find their NYC governmental districts by address or lat/lng (http://staging.placeanddisplaced.org). It works, but its kinda slow, especially when searching through districts that have complex polygons. Can anyone give me some pointers on optimizing this code...
