Description:
------------
In PHP4 xml_parse_into_struct() can parse an UTF-8-encoded XML file
with or without a UTF-8 BOM (\xEF\xBB\xBF). In PHP 5, this is no longer
the case and it raises an error saying the string doesn't contain any
XML data (Empty document).
Additionally PHP 5's xml_parse_into_struct() does *NOT* place default
attribute values into the struct (e.g. despite the DTD provided,
$content[1]['attributes']['type'] isn't set to "literal" in actual
result section below ; please compare it to expected result.) This used
to work under PHP 4.1.x and above (but the parser is based on expat
AFAIK.)
PS: I guess "manually" stripping this magic number -- if embedded --
before calling the function would yield the expected result. However I
found an acceptable work-around that seems to work equally well across
versions 4 and 5 of PHP :
<?php
...
$parser = xml_parser_create('');
xml_parser_set_option($parser, XML_OPTION_TARGET_ENCODING, $encoding);
...
?>
Rather than:
<?php
...
$parser = xml_parser_create($encoding);
...
?>
Reproduce code:
---------------

; running PHP 4 --> outputs expected result

; source code
Expected result:
