Change line 34 to:

objs = srcs.collect do |srcfile|

(ie. change src → srcs)

Tnx, but now i have this error:  
C:\libxml\libxml-ruby-0.5.4\ext\libxml\>ruby extconf.rb  
extconf.rb:51: (eval):11: compile error (SyntaxError)  
(eval):2: unknown regexp option - h  
(eval):9: syntax error, unexpected ‘.’  
(eval):11: syntax error, unexpected $undefined  
hdrdir = $(topdir)

There is a gem to intall it without any error, or could u help me to  
install without gem install command?

Ah, you are installing on Windows. I’m afriad the extconf.rb code is  
“under development” with regard to Windows. Let me get back to you.

Yes im using windows. sorry for not telling that; i really need libxml  
because i was using rexml am my xml file is a little big (~1000 lines  
for the moment) and methods like find\_first\_recursive are slow(~10  
seconds) so i need something faster.

Tnx for the help.
