Numbers In XML Tags

I created a simple script in which you could interact with an AI through a chat a few years ago. All phrases and questions were stored in an XML document, but suddenly I ran into some trouble, the script just wouldn't work. I remember I spent quite some time trying to find errors in the code structure, but I never found it, so the work was discontinued and stashed away. I picked it back up again today and it turns out I had been using numbers at the start of a series of XML tags. If you work with XML you should know that tags can't start with a number, so I've been doing some restructuring, and hey, it works again! Check out the script in the stuff directory. Or you could just click this link. The vocabulary is still a bit limited, but at least it works. :)
