i already asked a similar question in the
cocoon-users mailing list, so please excuse this, but since i got no answers and
it wasn't really a cocoon specific question i'm gonna place it here once
more...changed a bit.
I'm writing a Transformer for Cocoon... as input i
have the DOM representation of a document. Let's say a part of this document
I went Home
Stored in a variable i have the id of a node, in
this case "sometext". Furthermore I have a variable called pointer, which looks
like "string-range(.,"Home") ..something
like this. It should be a proper XPointer expression, I can change that to
whatever I want though.
Now the goal of the Transformer is to write an
anchor around the string pointed to - "Home" in this case - which occurs in the
node defined. I can make the span the context node and Java allows me
to insert nodes before and after this one.. but how can i write an anchor around
the specified string within this node?
Of course I could get the string, iterate through
it and search for the word etc, but that would be a pain, esp. since there could
be 18 instances and I would want the 17th etc.
Actually I'd like to use XPointer, so that some
function returns the specified string-range in the node, and I can surround it
with an <a> tag... that's what I thought ;)
So, is there an XPointer implementation that allows
me that .. or how would you solve that problem?
