xpathr – first iteration

In this first iteration, unauthenticated users should be able to test xslt code, save snippets and eventually come back to edit them without signing up. xpathr will work without javascript enabled, so client side code shouldn't be taken in consideration for now.

UI:

XML textarea
XSL textarea
RESULT read-only textarea

Authenticating users against mysql

I couldn't find any relevant information for getting this to work on ubuntu precise, so I'm writing my founds here.
It's actually pretty simple, this approach doesn't involve PAM but just NSS. The implications are clearly explained in the FAQ of the nss-mysql module:

NSS stands for NameService Switch. NSS allows you to implement access to various data using any number of modules. This means that when the operating system wants to look up the user "cinergi", it doesn't have to know how - it calls upon the NSS system to perform the task. In turn, we can now configure NSS to look for users in traditional places like /etc/passwd, NIS, LDAP, and now (using this module), MySQL. The NSS
