REXML : add text to element without temp variable?

ruby-talk
1

Say I'm trying to make this XML:
<music>
  <artist>Pink Floyd</artist>
  <album>Dark Side of the Moon</album>
</music>

Right now I'm doing this:
doc = Document.new
music = doc.add_element 'music'
artist = music.add_element 'artist'
artist.text = 'Pink Floyd'
album = music.add_element 'album'
album.text = 'Dark Side of the Moon'

QUESTION:
Why create variables for artist and album?
Shouldn't there be a way to add the text directly, without creating an
in-between (and never used again) variable?

Like this:
music.add_element('album').text = 'Dark Side of the Moon'

or this:
music.add_element('album').text << Text.new('Dark Side of the Moon')

Has anyone found a shortcut like this?

doc = Document.new
music = doc.add_element("music")
music << Element.new("artist").add_text("Pink Floyd")
music << Element.new("album").add_text("Dark side of the moon")

Thanks everyone for your help.
You're right, this works great:

doc2 = REXML::Document.new
music = doc2.add_element 'music'
music.add_element('artist').text = 'Pink Floyd'
music.add_element('album').text = 'Dark Side of the Moon'

Not sure why it wasn't working last night, except maybe I needed some
sleep. :slight_smile:

Or some more energetic music!? :slight_smile:
