PHP DOM function read line number from input file

I have a program that reads an XML file using DOM functions:

$doc = new DOMDocument('1.0');
$doc->load("myFile.xml");

As I traverse the nodes in this document, is there a way to determine which line in the input file a node was defined on?

For instance:

1: <!-- myFile.xml -->
2: <foobar>
3:     <foo>FOO</foo>
4:     <bar>BAR</bar>
5: </foobar>

and PHP:

$xp = new DOMXPath($doc);
$bars = $xp->query("//bar");
$myBar = $bars[0];
echo "The first <bar> element is on line " . performMagicHere(); // 4

$element->getLineNo()

will return the line number of the open tag. Note: for opening tags that span more than one line, it will return the end of the open tag. It doesn't seem to work for DOMText nodes (returns 0).

You cannot do this with the PHP DOM class. DOM Level 3 added support for this , but we don't have DOM Level 3 support in PHP yet.
