XPath functions in templates

[BillVelasquez]

This is a question, not an issue:

In Nustache you can use an XML document as the data for rendering, and then you can use XPath expressions that return nodes in the templates, like {{parent/child/node}}

Is it possible to use XPath functions in the templates?

It'll be really powerful to use something like {{sum(i­tems/price)}}

That currently isn't something that is offered. You could implement something similar by creating a ValueGetterFactory and ValueGetter looking at XmlNodes and then compiling the expression and trying to run it. Hopefully this gives you the right direction.
