The 65535 line number limit is no longer a problem when you use libxml 2.9 or higher, but you have to explicitly enable support for big line numbers:
<?php
define('XML_PARSE_BIG_LINES', 4194304);
$dom = new DOMDocument;
$dom->loadXML($xml, XML_PARSE_BIG_LINES);
?>
DOMNode::getLineNo
(PHP 5 >= 5.3.0, PHP 7, PHP 8)
DOMNode::getLineNo — Get line number for a node
Description
Gets line number for where the node was defined at parse time.
Parameters
This function has no parameters.
Return Values
Returns the line number where the node was defined at parse time.
If the node was created manually, the return value will be 0.
Examples
Example #1 DOMNode::getLineNo() example
<?php
// XML dump for below example
$xml = <<<XML
<?xml version="1.0" encoding="utf-8"?>
<root>
<node />
</root>
XML;
// Create a new DOMDocument instance
$dom = new DOMDocument;
// Load the XML
$dom->loadXML($xml);
// Print where the line where the 'node' element was defined in
printf('The <node> tag is defined on line %d', $dom->getElementsByTagName('node')->item(0)->getLineNo());
?>The above example will output:
The <node> tag is defined in line 3

This function is buggy. It doesn't always return the correct line number, especially for text elements. As an alternative you can do something like this:
<?php
$text = $node->ownerDocument->saveXML($node);
$line += substr_count($text, "\n");
?>
You'll want to keep a reference to $line (starting at 0) and add to it as you parse over the document recursively.
In order for this to work you have to tell DOMDocument to preserve white space before loading the document.

The DOMNode::getLineNo() method doesn't work properly due to a libxml2 bug.
