Summary: DOMNode::getLineNo() doesn't return line number
higher than 65535
Status: Not a bug
Type: Bug
Package: XML Reader
Operating System: Windows 7
PHP Version: 5.3.5
Block user comment: N
Private report: N
New Comment:
The function DOMNode::getLineNo() is not able to return a line number higher
than 65535.
Test Script:
<?php
$xml = "<?xml version=\"1.0\"?><root>".str_repeat("\n", 65537)
."<mix>end</mix>\n<mix>end</mix></root>"
;
echo dom_import_simplexml(
end(simplexml_load_string($xml)->xpath('//text()'))
)->getLineNo()
;
?>
Expected result: 65537
Actual result: 65535
Summary: Reported back in 2007, upstream does not know how to fix this w/o
breaking stuff (binary compatibility).
It's also worth to mention that normally files with more than 65k lines aren't
written by hand so don't require that
type of functionality. Naturally this is subjective.
To fix this this requires a different upstream/patch of one of the underlying
libraries, e.g. libxml2. The debian
ticket has a patch.

Sorry, but your problem does not imply a bug in PHP itself. For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions. Due to the volume
of reports we can not explain in detail here why your report is not
a bug. The support channels will be able to provide an explanation
for you.
Thank you for your interest in PHP.
Known limitation of libxml2

Description:
------------
DOMNode::getLineNo() doesn't return line number higher than 65535.
I assume that unsigned short is used for file line enumeration either in
XMLReader
or DOMNode internals.
Test script:
---------------
Try reading with XMLReader an XML file that has more than 65535 lines.
Then, when line nr. > 65535 is reached, call XMLReader::expand()->getLineNo().
Expected result:
----------------
Correct line number.
Actual result:
--------------
65535 for lines, higher than 65525.
