Hi Folks,
I dug out my old compiler "Dragon book" and started rereading it.
Chapter 1 lists some of the tools that employ compiler techniques. This one
caught my attention:
Query interpreters: A query interpreter translates a predicate containing
relational and boolean operators into commands to search a database of records
satisfying that predicate.
An XPath expression is a query. Not against a database, but against an XML
document. Are XPath expressions parsed using compiler parsing algorithms? Is a
syntax tree constructed for an XPath expression? Is the syntax tree traversed?
