Hi all. I've enjoyed(?) reading over the February/March thread
entitled "Musings on operator overloading". I've brought a few
thoughts along; if they're old news, please tell me
here to do more reading on it :).
The Perl6 way to do this is grammars; using an XML grammar to pull
data out of an XML document is one of Larry's favorite examples.
Ok, great. While I see how this does a great job of converting the
string of data into a plex, it doesn't solve the problem of
selecting the data from the plex in a glob-like (or XPath-like)
fashion, which is what I'm talking about here. Have I missed
something that will do that?
I could have sworn there was a short and elegant example of using a
grammar to extract arbitrary information from an XML document, but I
don't see it in the documentation. I recall Trey Harris showing such
an example on IRC but not in a logged channel; maybe he'll see this
message and jump in, or if not I'll see if I can get him to write
another example.
