I hate XML.
With PHP, I couldn’t get “get_attribute” to work on the child nodes. The PHP docs are frightening. It took me too long to figure out I had to install the php4-domxml debian package just to get started. It is really dumb writing XML code in PHP4, because everything changes in PHP5. Nightmare.
Unix style flat files rule. I hate it how some applications that use CSV are migrating to XML and other stupid interfaces.
