Basically I want to strip the document of words between blockquotes. I'm a regular expression newb and even after using rubular, I'm no closer to the answer.
Any help is appreciated.

A:
Use an HTML parser and forget regular expressions. Regex is incapable of correctly handling HTML.
doc = Nokogiri::HTML(your_html)
doc.xpath("//blockquote").remove
From: Strip text from HTML document using Ruby
There are more examples of how to use Nokogiri and XPath, if you look around.

This fails for `<blockquote>Some <b>bold text</b></blockquote>`. As I said: Regex is *technically incapable* of correctly handling HTML.

A:
Sample string:
<blockquote>Hello world</blockquote>
type the following regex in rubular <blockquote>(.+?)<\/blockquote>
or for something more generic:
<.*?>(.+?)<\/.*?>
hope it helps!

This fails for `<blockquote>Some <blockquote>quoted text</blockquote> within a quote.</blockquote>`.

if we are just talking ruby:resultarray = htmlstring.split(/<.*?>/). The split() method will disregard the regex match and the text between the matches is kept. FYI: the scan() method will perform the opposite of this. if you're a newb, i suggest to spend some time learning regexs, it's pretty language agnostic and will serve you well.

If this comment was for me: No, I'm not a "newb" as far as regular expressions go. ;) And `htmlstring.split(/<.*?>/)` fails for `<b title="HTML is > than RegEx">Don't do HTML with RegEx</b>`.
