Sorry, an error in statement - correct version
$ch = substr($data, $byte, 7);
The "bug" still stands though...

Description:
The function xml_get_current_byte_index() returns byte index according
to utf8 encoded text - disregarding if input is in ISO-8859-1. If you
would like to cach a chunk of data from a xml file you would need to
convert input to utf8 to get the correct calculations.
Reproduce code:
---
$data = "\n\nøææø\nÆØÅdata\n\n";
function startElement($parser, $name, $attrs)
{
global $data;
if($name != "ROW") return;
$byte = xml_get_current_byte_index($parser) + 41;
$ch = substr($data, $byte + 41, 7);
# The following calculates correct
# $ch = utf8_decode(substr(utf8_encode($data), $byte, 7));
echo "$name ($byte): $ch\n";
exit();
}
function endElement($parser, $name)
{
}
$xml_parser = xml_parser_create();
xml_set_element_handler($xml_parser, "startElement", "endElement");
xml_parse($xml_parser, $data, 1);
Expected result:
ROW (79): ÆØÅd
Actual result:
