EXSLT dates-and-times seems to be broken #20

Open mied opened 9 years ago

mied commented 9 years ago

I want to use the date xslt extension for some xml/xslt transformations but the implementation seems to be broken. I use this test file to check if the date functions work:

from amara.xslt import transform

XML_DOC = """<?xml version="1.0"?>
<durations>
    <duration>P4Y8MT7H</duration>
    <duration>P17Y1MT2H</duration>
    <duration>P1Y2MT2H</duration>
</durations>"""
XSL_STYLESHEET = """<?xml version="1.0"?>

print transform(XML_DOC, XSL_STYLESHEET)

Runing this file fails with a stack trace. It seems like the implementation in amara/xslt/exslt/datetime.py is broken (missing imports,...). Did I do something wrong or can somebody else confirm this?
