PHP Bug Type: XML related
Bug description: PHP5 freezes when parsing XML document without prolog
Description:
------------
When parsing a XML document without a prolog PHP5 seems to "freeze", never
returning from xml_parse and never calling the call backs. This is
reproducible on both Debian/PHP 5.0.2 with libxml 2.6.11 and Mac OS X/PHP
5.0.3 with libxml 2.6.7
I've attached the simplest possible example to demonstrate this (probably
best to run it from the command line, but the problem is reproducible
running under Apache and from the command line)
Reproduce code:
---------------
<?php
$xml1 = '<?xml version="1.0"?><greeting>hello world</greeting>';
$xml2 = '<greeting>hello world</greeting>';
$parser = xml_parser_create('');
xml_set_element_handler($parser, "startElement", "endElement");
$status = xml_parse($parser, $xml1, true);
function startElement($parser, $name, $attrs) {
echo "start $name\n";
}
function endElement($parser, $name) {
echo "end $name\n";
}
?>
Expected result:
----------------
I would expect to see the program echo "GREETING", and then end. This is
what happens when you run this same script under PHP4
Actual result:
--------------
It just sits there until you kill it.
