Convert an arbitrary string to xml in ruby

In Ruby 1.9.2 to escape XML special characters in Strings, use the 'encode' method.

Example, if you have:

my_string = 'this is "my" complicated <String>'

For XML attributes use:

"<node attr=#{my_string.encode(:xml => :attr)} />"

Generates:

<node attr="this is "my" complicated <String>" />

For XML text use:

"<node>#{my_string.encode(:xml => :text)}</node>"

Generates:

<node>this is "my" complicated <String></node>
