Comments on: Macports updates their Erlang version, update your load-path’s http://blog.lnx.cx/2010/02/03/macports-updates-their-erlang-version/ not at all like a diatribe Mon, 31 Oct 2011 14:55:36 +0000 hourly 1 http://wordpress.org/?v=3.3.1 By: tbielawa http://blog.lnx.cx/2010/02/03/macports-updates-their-erlang-version/comment-page-1/#comment-72 tbielawa Wed, 03 Feb 2010 12:21:49 +0000 http://blog.peopleareducks.com/?p=115#comment-72 Kenneth, At the time "good" just meant the first thing that <em>looked</em> good. When reading over documentation for each module I noticed where I could find an example of how to use a continuation function in Erlsom before I found the Xmerl example. Honestly I haven't tried either module yet, though. Right now I'd much rather go with something that ships with my distribution than require an external dependency in each installation. Just before you made your comment I read Jack Moffitt's post in which he <a href="http://metajack.im/2008/10/28/chunked-xml-parsing-in-erlang-with-xmerl/" rel="nofollow">parses a TCP stream with xmerl</a>. After which I realized that that he was doing it the same way I would have in Erlsom, just with xmerl. While I would like to pass binaries straight out of gen_tcp:recv() to the scanner, I recognize that I do not have ultra high performance needs at this time, so the conversion to strings will only be an additional operation, and in no way a game killer. I'm going to give Xmerl a try. Can you comment on the prospects of binary scanning coming to xmerl, and if there would be noticeable performance gains at this point? Kenneth,

And I also wonder if you are aware of the brand new XML parser in the xmerl application (included in the Erlang/OTP distro). The new XML parser is a sax parser with about the same speed as Erlsom. There is currently no validation but that is on its way. /Kenneth , Erlang/OTP Ericsson I am just curious regarding what you mean with good XML parser?
