I have an almost working XPath grammar. Yay!

Hello
        'text' parses OK
        'comment' parses OK
        'text()' parses OK
        'processing-instruction('poo')' parses OK
        'processing-instruction("poo")' parses OK
        'processing-instruction()' parses OK
        'self::name' parses OK
        '@fruit' parses OK
        'one/two' parses OK
        'one/@fruit' parses OK
        'one/@fruit[1]' parses OK
        'one/descendant-or-self::woot[1]' parses OK
        'one/two/three' parses OK
        'one/two/three[1]' parses OK
        'one/two[1]/three' parses OK
        '/one/two' parses OK
        '/one[1]/two[2]/comment()' parses OK
        '/one[1]/two[2][1]' parses OK
        '//one' parses OK
        '//one/two' parses OK
        '//one/two//@id' parses OK
        'one/two/three[@attr]' parses OK
        'one/two/three[@attr][1]' parses OK
        'one/two/three[four/@attr]' parses OK
        'one/two/three[@attr='nob']' fails Parsing
        'one/two/three[position() = first()]' fails Parsing
        'one/two/three[(@attr) or (@id)]' fails Parsing

If you're interested, the code is in the CVS as xpath-dev-sandbox. You'll need a current version on Boost, or Spirit 1.6. So far, it is just the grammar, but everything else is just a simple matter of programming ...
