[OT] Which is the fastest XML/XSL engine?
Hi, This is rather off topic, but since I will be running this under mod_perl: What is the fastest technology available for transforming XML using XSL under perl/mod_perl on apache? The only perl api I'm aware of is XML::XSLT which is not particularly fast. I'd like to do transforms in realtime for a high traffic site. thanks, Mark.
Re: [OT] Which is the fastest XML/XSL engine?
Thanks very much for your super fast replies. LibXSLT looks awesome. I found some benchmarks which you're probably aware of: http://iterx.org/essays/2002/02/22 Thanks again, Mark.

Try the XML::LibXML and XML::LibXSLT modules, which use the Gnome project's XML and XSLT C libraries: http://search.cpan.org/author/PHISH/XML-LibXML-1.52/LibXML.pm http://search.cpan.org/author/MSERGEANT/XML-LibXSLT-1.51/LibXSLT.pm http://xmlsoft.org/ http://xmlsoft.org/XSLT/ They're extremely fast, in my experience. regards, Ben
Re: modifying @INC at startup and version of perl used
Jamie, Use the perl internal variables to figure out what version you're running under: $] and $^V Use these whether you're running perl or mod_perl. You might want to direct questions relating to perl in general to the perl beginners list. Please see perldoc perlvar for more details. ~mark.

I need to know how to find out exactly which version of perl mod_perl is configured to use, and if this can be changed as a non-root user, and how to set the @INC. I have a simple startup script that prints @INC, which prints @INC: /sbcimp/run/pd/perl/5.005_03/lib/sun4-solaris /sbcimp/run/pd/perl/5.005_03/lib /sbcimp/run/pd/perl/5.005_03/lib/site_perl/sun4-solaris /sbcimp/run/pd/perl/5.005_03/lib/site_perl this makes me think I am running 5.005_03? In the conf file I have PerlSetEnv PERL5LIB /sbcimp/run/pd/perl/5.6.1/lib:/sbcimp/run/pd/cpan/5.6.1-2002.06/lib but this does not seem to update the @INC. (I've also tried combinations of PERLLIB and SetEnv etc). When this is set however I get the following errors Can't locate object method boot via package mod_perl at /sbcimp/run/pd/perl/5.005_03/lib/site_perl/sun4-solaris/Apache/Constants.pm line 8. and [Thu Aug 29 10:41:12 2002] [error] syntax error at /sbcimp/run/pd/perl/5.6.1/lib/warnings.pm line 306, near {^ syntax error at /sbcimp/run/pd/perl/5.6.1/lib/warnings.pm line 311, near {^ etc, which is making me think I am mixing incompatible perl binaries and modules. Does that seem reasonable, and if so what can I do to use perl 5.6.1?

$r-print() with slow clients and stop button
Hi, I've created a meta-search that prints out status messages to the browser as it receives responses from the servers it is searching by setting $|=1 and using $r-print. It runs as a mod_perl handler. I'm running apache 1.3.24 and mod_perl 1.26 on Linux. I'm finding that my web app has slowed down radically since I started doing this. I've tracked it down to the $r-print statements. I suspect that each statement is waiting for acknowledgement from the client before it will continue execution. Sometimes children are tied up for 2 minutes! I suspect these may be where the client has dropped its dialup connection and $r-print is waiting for acknowledgement of a packet. Has anyone else had this problem? I've set httpd.conf's Timeout setting to 5 seconds as a temporary fix. As I understand it, this will affect the amount of time perl waits before triggering soft_timeout or hard_timeout when doing $r-print operations? I'd like to somehow send data to the client and have execution continue until the end of a time critical section, after which it will wait for acknowledgement of all data that was sent and if that is not received within X seconds, kill the connection and return OK. The only way I can think of doing this is to get the client socket connection, temporarily change it to non blocking, do a send on it, finish the piece of code, and then change it back to non-blocking once I've confirmed the data was sent correctly. I'm afraid (very afraid) that this will break apache or mod_perl somehow. Does this sound like a workable solution? My C isn't too hot, so I'll be coding the entire thing in Perl and running it as part of the handler. Is there a better or easier way to do this? thanks, ~mark http://www.workzoo.com/ [EMAIL PROTECTED]
