object attr extends AttrHelper[Box]

Used to get an attribute by its name. There are several means to getting attributes:

  // Get a Box for the attribute:
  val myAttr = S.attr("test") openOr "Not found"

  // Get an attribute or return a default value:
  val myAttr = S.attr("name", "Fred")

  // Apply a transform function on the attribute value, or return an Empty:
  val pageSize = S.attr("count", _.toInt) openOr 20

  // There are also prefixed versions:
  val prefixedAttr = S.attr("prefix", "name") openOr "Not found"

Note that this uses the data held in S.attrs, which means that it will find attributes through the entire snippet nesting stack. For example, given the snippets:

<lift:MyStuff.snippetA foo="bar">
  <lift.MyStuff.snippetB>...</lift.MyStuff.snippetB>
</lift:MyStuff.snippetA>

Calling S.attr("foo") from snippetB will return Full("bar").
