apologies, I withdraw my bug report.
The problem was 2 things
a) script time outs
b) invalid XML
------------------------------------------------------------------------
[2002-05-09 07:24:46] [EMAIL PROTECTED]
Running PHP4.2.0 on IIS on NT4 server.
I am trying to parse large XML files with PHP. When I run the code on
a smaller 66kb file, it runs with the desired affects. But when I try
to run it on a large file (around 2mb), it takes its time doing
xml_parse_into_struct. Also, sometimes the PHP script can make the
memory usage of IIS spiral uncontrollably, and the CPU usage is maxed
out.
Please help, or tell me whats wrong
Thanks in advance
