Hi!
I''m trying to parse a XML document (MusicXML), I found that here
something about it:
http://railstips.org/blog/archives/2008/08/11/parsing-xml-with-ruby/
- I chose Hpricot, but I have a problem: in XML document, which I''m
trying to parse, there are names of blocks with minus sign, for
example <score-partwise>. In Hpricot it should looks something like
this:
xml = File.read(path)
puts Benchmark.measure {
doc = Hpricot::XML(xml)
(doc/:score-partwise).each do |s|
# here we have s as each score-partwise block
end
}
But it throws undefined local variable or method `partwise'' for
#<MusicxmlController:0xb6badff4>, becouse in symbols names minus sign
is prohibited. How can I make a symbol name with minus sign?
cheers,
simon

How can I make a symbol name with minus sign?Just use a string instead: (doc/''score-partwise'') Best regards Peter De Berdt -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

How can I make a symbol name with minus sign?Well, you can actually have any characters you like in a symbol name. The :name syntax only works if the symbol name doesn''t contain "weird" characters, but the following syntaxes will work regardless: :''name-with-weird-characters'' :"name-with-weird-characters-and-#{variable_interpolation}" ...or just use String#to_sym . We are now well out of Rails territory and into basic Ruby, so further discussion probably should go to the main Ruby list.> > cheers, > simonBest, -- Marnen Laibow-Koser http://www.marnen.org marnen-sbuyVjPbboAdnm+yROfE0A@public.gmane.org -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
