[lxml-dev] NotImplementedError for external functions with xsl:variable's

[Dmitri Fedoruk]

Hello everybody,

To be frank - it's not like that. We used variables just as function
parameters (e.g. a float number). But using a tree is a very powerful
feature, too.

lxml.etree: (2, 2, -199, 59835)
libxml used: (2, 6, 30)
libxml compiled: (2, 6, 30)
libxslt used: (1, 1, 22)
libxslt compiled: (1, 1, 22)
I've attached the test source. In brief - it works :) I tried to test the
variable as a number literal, as a string and as a tree. I got expected
results in all cases.

I'll try to - sorry, nothing has came up to my mind yet. Maybe we'll
encounter some tricky cases in our templates, then I'll report them.
Cheers,
Dmitri
