I'd thought I would post this to help those who may want to know how to get the libxml DOM extensions installed
PHP uses the Gnome XML library which is developed by www.xmlsoft.org
For Windows 32 platforms, the maintainer is Igor Zlatkovic. You can obtain the Windows 32 binaries here:
http://www.zlatkovic.com/projects/libxml/binaries.html
Download the libxml and iconv distributions
Copy iconv.dll and lib2xml.dll in the windows\system32 directory
Open up the php.ini file located in the windows directory
Remove the semicolon to enable:
extension=php_domxml.dll
Add the following:
extension_dir = c:\Php\php-4.2.2-Win32\extensions
Run phpinfo() and you will see the following:
domxml
DOM/XML enabled
libxml Version 2.4.21
HTML Support enabled
XPath Support enabled
XPointer Support enabled
To prove binding, run a simple call:
$dom = domxml_new_doc('1.0');
Hope this helps someone!
