Hi,
I am trying to parse a xml file with mkiv to process a list of invoices
(factuur in dutch).
The xml file looks like this
<?xml version='1.0 standalone='yes' ?>
<factuur>
<nummer>123456789</nummer>
<datum>1 januari 2008</datum>
<medewerker></medewerker>
<regels>
<omschrijving>Omschrijving geleverde dienst a</omschrijving>
<bedrag>1500,00</bedrag>
<omschrijving>Omschrijving geleverde dienst b</omschrijving>
<bedrag>200,00</bedrag>
</regels>
</factuur>
I want to extract and sum the invoices (regels). I managed to get things
working (printing)
but don't know how to assign these values into lua variables for the
summing.
The test code looks like this
% engine=luatex
\starttext
\startluacode
document.xml = document.xml or { } -- define namespace
document.xml = xml.load("factuur.xml") -- load the file
n = xml.count(document.xml, "/factuur/regels/omschrijving")
for i = 1, n do
--
-- here I want to assign the values returned by xml.filter into local
variable amount
--
xml.sprint(xml.filter(document.xml, "/factuur/regels/bedrag/position("
.. i .. ")" ))
end
\stopluacode
\stoptext
Kind regards
