When trying to install something, you will get the error: pear.php.net is using a unsupported protocal '" This should never happen. install failed. This problem comes from corrupted channel files. Go into your PEAR php directory and backup .channels directory.

If you go into your PEAR installation and move the .channels directory out of the way then run an "update-channels" the issue should be corrected. Unfortunately, this also means you loose all channels you'd subscribed to, but does save you from having to reinstall PEAR completely.

I was finding a way to refer that element as a SimpleXMLElement and found a nifty note in PHP Manual. It says if you have unsupported (unsupported in PHP Lexicon for a variable name) characters inside the name of a node, you can access it using a special pattern {'name'}.

In his example, he shows how a popular phrase ("i can have cheese burger") can be used as the variable name despite having spaces in it.
