Regex is the wrong tool for handling HTML (or XML) 99.9% of the time. Instead, use a parser, like Nokogiri<\/a>:<\/p>\n

require 'nokogiri'\n\nhtml=\"<img src=\"https:\/\/filin.mail.ru\/pic?width=90&amp;height=90&amp;email=multicc%40multicc.mail.ru&amp;version=4&amp;build=7\" style=\"\">\"\ndoc = Nokogiri::HTML(html)\n\nurl = doc.at('img')['src'] # => \"https:\/\/filin.mail.ru\/pic?width=90&height=90&email=multicc%40multicc.mail.ru&version=4&build=7\"\ndoc.at('img')['style'] # => \"\"\n<\/code><\/pre>\n
Once you’ve retrieved the data you want, such as the src<\/code>, use another “right” tool, such as URI<\/a>:<\/p>\n
require 'uri'\n\nscheme, userinfo, host, port, registry, path, opaque, query, fragment = URI.split(url)\nscheme    # => \"https\"\nuserinfo  # => nil\nhost      # => \"filin.mail.ru\"\nport      # => nil\nregistry  # => nil\npath      # => \"\/pic\"\nopaque    # => nil\nquery     # => \"width=90&height=90&email=multicc%40multicc.mail.ru&version=4&build=7\"\nfragment  # => nil\n\nquery_parts = Hash[URI.decode_www_form(query)]\nquery_parts # => {\"width\"=>\"90\", \"height\"=>\"90\", \"email\"=>\"multicc@multicc.mail.ru\", \"version\"=>\"4\", \"build\"=>\"7\"}\n<\/code><\/pre>\n<\/p><\/div>\n
