BindHelpers.currentNode is a Box[NodeSeq] that gives you the node that
bind is currently replacing.

[Lift] Re: bind with outer element?
Hi,
I actually solved by wrapping the node i cared about in another node,
but tried the FuncBindParam and it does seem to only grab the child
nodes.

Doesn't the FuncBindParam only get the element's child NodeSeq?

try:
def myFunc(node: NodeSeq): NodeSeq = if ((node \ "@shorten").isEmpty)
longVersion else shortVersion
bind("t", x, FuncBindParam("name", myFunc _))
You get the complete passed to myFunc.

try:

longVersion else shortVersion
bind("t", x, FuncBindParam("name", myFunc _))

If I'm not mistaken, S.attr is an attribute on the snippet xml node; for the
node currently being processed by bind you use BindHelpers.attr

Jon,
To read attributes, you do the following:
S.attr("shorten") // => Box[String]
