symfony propel-build-model wamp error due to XSL extension

Description:   I was trying to run the symfony PHP framework. I tried to build the model using command
php symfony propel:build-model.

And it gave error Could not perform XSLT transformation. Make sure PHP has been compiled/configured to support XSLT.

Environment: Wamp server 2.0, PHP 5.2.5, Apache 2.2.6.

Reason: PHP-XSL extension is not enabled. By default, Wamp server doesnt enable php-xsl php extension. and php-xsl is required.

Solution: Enable php-xsl extension.

left click on WAMP’s tray icon and than in PHP>PHP extensions select php-xsl and enable it.But there is one more php.ini file, which WAMP won’t change, we need to do it by hand, open: C:\wamp\bin\php\php5.2.5\php.ini and remove “;” from the line xsl.dll
