Ok, I give up ... How do I install DOMXML on PHP4.3.0

[bissatch]

Hi,

I have installed Apache2. I have installed PHP4.3.0. All is working
fine.

I have now went and tried to install DOMXML into PHP by simply
uncommenting the extension = php_domxml.dll (or something like that) in
php.ini. Unfortuntely I get the following error at a part of my PHP
page where I try to load a xml file:
Warning: domxml_open_file(): I/O in C:\Program
Files\Apache\Apache2\htdocs\csp\home\index.php on line 28

Warning: domxml_open_file(): warning : in C:\Program
Files\Apache\Apache2\htdocs\csp\home\index.php on line 28

Warning: domxml_open_file(): failed to load external entity
"../xml/menu.xml" in C:\Program
Files\Apache\Apache2\htdocs\csp\home\index.php on line 28
I have check phpinfo() and domxml is enabled. I have also tried a whole
host of combinations with apache1/apache2 and php4.0.0/php4.3.0/php5
but was informed that php 4.3.0 had best compatibility with the version
of domxml i am familiar with (as ive heard that php5 has yet a new set
of DOM commands).

Is there anything else that I should be doing apart from commenting out
the extensions = ... line? Cheers
