You can do this by changing the file generator which reads the template
file into a "jx" generator. Then you can use ${...} or #{...}
everywhere. More information about the JXTemplate generator can be found

In different ways. For one, to stay in the same sphere as above, pass on
your XML document to the view layer by passing it in the bizdata
argument of the showForm method (assuming you're using flowscript --
though it's not different for apples).

in the flowscript you would do something like this:

bizdata = {"myxml": myxmldoc};
form.showForm("the-pipeline", bizdata);

and in the template XML file somewhere:

<a href="http://blabla/#{myxml/some/elements/deep/sku}"/>

(warning: the above is only pseudo-code)

Alternatively, you could also load the value into an output widget, and
then either use a specific stylesheet template to render it into the
correct link, or again use the jxtemplate generator to extract the value
using a jexl or jxpath expression (the woody form is available as a
variable called "woody-form").
