| # Advanced to_xml | |

| # Provide to_xml support to things like strings, | |
| # so you can now actually do ['foo'].to_xml without | |
| # it throwing an exception. | |
| # | |
| # One gotcha to look out for is Rails calls | |
| # to_xml in the render method, so: | |
| # | |
| # render :xml => {:foo => 'bar'}.to_xml(:title => 'widget') | |
| # | |
| # produces: | |
| # | |
| # <?xml version="1.0" encoding="UTF-8"?> | |
| # <string><?xml version="1.0" encoding="UTF-8"?> | |
| # <hash> | |
| # <foo>bar</foo> | |
| # </hash> | |
| # </string> | |
| # | |
| # The solution is to bypass Rails' magic: | |
| # | |
| # render :text => {:foo => 'bar'}.to_xml(:title => 'widget'), | |
| # :content_type => Mime::XML | |
| # | |
