There is this HTML code:

<span class="title">Название:</span> Rising Water - James Vincent McMorrow<!-- После слитно еще несколько span -->

I'm trying to parse it:

puts /<span class="title">Название:<\/span>(.*)-(.*)/.match(line)

But it doesn't come out. I get the name and the spans following it.
Help me please.

It is not worth parsing with a regular expression, the above mentioned is quite suitable, rubyists often use the nokogiri library for parsing sites.
It is quite convenient, for example, because you can get to elements by ccs selectors.

Example:

doc = Nokogiri::HTML('<body><span class="title">Название:</span> Rising Water - James Vincent McMorrow<span></span><body>')

name = doc.xpath('//span/following-sibling::text()[1]').text

p name # => " Rising Water - James Vincent McMorrow"

HTML DOES NOT PARSE WITH REGULATORS. REGEXP IS A TOOL NOT COMPLEX ENOUGH FOR HTML PARSING.
