BindParam that computes an optional new attribute value based on the current attribute value. Returning None in the transform function will result in the Attribute being omitted. For example, given the following markup:
The following snippet:
import scala.xml._ class AttrBinds { def render(xhtml : NodeSeq) : NodeSeq = BindHelpers.bind("test", xhtml, FuncAttrOptionBindParam("x", { ns : NodeSeq => Some(Text(ns.text.toUpperCase + "X")) }, ("lift","calcId")), FuncAttrOptionBindParam("y", { ns : NodeSeq => if (ns.text.length > 10) { Some(Text(ns.text.length + "Y")) } else { None }, ("lift","calcId")))produces this markup:
