How to get builder 2.0 to escape attributes in rxml

Rails
1

I am using rxml to produce opml files and need to escape ampersands in
the attributes.

builder 2.0 docs found at http://builder.rubyforge.org/ show the
following

xml = Builder::XmlMarkup.new
xml.sample(:escaped=>“This&That”, :unescaped=>:“Here&There”)
xml.target! =>

I tried to install and repeat this result, but attributes are not
escaping

Here is the gem install and the attempt to test escaping attributes:

C:\rails>“c:\ruby\bin\ruby.exe” “c:\ruby\bin\gem” install builder
–version 2.0

Attempting local installation of ‘builder’
Local gem file not found: builder*.gem
Attempting remote installation of ‘builder’
Successfully installed builder-2.0.0
Installing RDoc documentation for builder-2.0.0…

C:\rails>cd buildertest

C:\rails\buildertest>ruby script/console
Loading development environment.

xml = Builder::XmlMarkup.new
=>
xml.sample(:escaped=>“this & that”)
=> “<sample escaped="this & that"/>”
exit

Does anybody know what could be wrong?

Alex,
Alex,

Use builder’s << operator to append text without escaping markup.

Example
xml.<< ‘This&That’

See also my blog post on using this in rxml templates:

Hope this helps,

Thanks for the reponse Zack, but my problem is the opposite. I need
Builder to escape the markup and it’s not doing it for some reason.

When I use buidler

this is what I get

C:\rails\buildertest>ruby script/console
Loading development environment.

xml = Builder::XmlMarkup.new
=>
xml.sample(:escaped=>“this & that”)
=> “<sample escaped="this & that"/>”
exit

If you look at the markup you can see that what is supposed to be
escaped is not.

I am running builder 2.0 and the specs say that it should escape
attributes, but for some reason it doesn’t seem to be working.

Any idea what might be wrong?
