Hi,

In an .rxml template, I need to have nodes named .  
However, if I use:

xml.cross-domain-policy

I get the following error:

undefined method `domain’

It works fine if I use xml.cross\_domain\_policy (undercores) to generate  
a tag \<cross\_domain\_policy\>. Unfortunately I need the dashes in the node  
names - how is it done?

For tags which have characters that are illegal in Ruby method names you  
can use the xml.tag! method in .rxml:

xml.tag! ‘cross-domain-policy’, ‘value’

or

xml.tag! ‘cross-domain-policy’ {  
xml…  
}

I cannot get this to work. I get an error in my Aptana IDE.

For example if I want to take:

```auto
xml.instruct!
xml.game_logs {
  xml.game{
    xml.name(@game.name)
    xml.id({:type => :integer}, @game.id)
  }
  @game_logs.each { |game_log|
    xml.game_log{
      xml.player {
        xml.name(game_log.player.login)
        xml.score(game_log.correct_answer_count)
      }
    }
  }
}
```

And make game\_log use dashes. What is the syntax? Thanks.

Actually I got it working in that example.

```auto
xml.game_logs {
```

becomes

```auto
xml.tag!('game-logs') {
```

but what about here:

```auto
xml.is_correct({:type => :boolean}, answer.is_correct)
```

this does not work:

```auto
xml.tag!('is-correct', {:type => :boolean}, answer.is_correct)
```

Nothing to see here - user error. That code works!

Thanks.
