Find a good tutorial on XPath. Yes, it evaluates left to right. From the context node, find its parent; find the parent of that; find its <statements> children; find their <assignment> descendants (at any depth), find their <var> children whose string value is the same as ... hmmm. actually I'm not sure what $dvar/string() was intended to mean, and I don't have time right now to check that.
