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/](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’

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?
