Hi, I was trying parse a xml feed from the St. Louis Fed Reserve Bank database (FRED) (see api @ http://api.stlouisfed.org/docs/fred/series_observations.html.) using Oleg's x2j sax parser.
I tried the various examples on the wiki as well as the one in the email below, and I kept getting the following error. process_px2j4_ TESTX2J4 |domain error: ParserCreate | PARSER=: ParserCreate<<0 When I finally hunted down the problem there was a reference to a 64bit dll that doesn't exist. fexist 'C:\j64-602\addons\xml\sax\lib\libexpat64.dll' 0 I was able to download a copy of the expat64 dll from http://www.gtk.org/download-windows-64bit.html (see Third party dependencies). It required renaming the dll to libexpat64.dll and putting it in ~addons\xml\sax\lib. Once I did this, everything worked perfectly. Thanks for great tool Oleg! I just wanted to point out this problem, so the addon can be fixed in JAL.

Seriously. Give it a try and let us know how it goes. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
