Description:
------------
"Warning: main() [function.main]: Cannot add element <XML-element-name> number 1 when only 0 such elements exist"
I get this error when trying to read from an xml-file.
In the file i need to jump to a parent-element from a child-element.
//Code:
if((int)$Verse_ID >= sizeof($Chap->Verse))
{
	if((int)$Chap_ID >= sizeof($Book[($Book_ID-1)]))
	{
		if((int)$Book_ID == sizeof($xml_Books->Book))
		{
			$Book_ID = 1;
			$Chap_ID = 1;
			$Verse_ID = 1;
		}
		else
		{
			$Book_ID++;
			$Chap_ID = 1;
			$Verse_ID = 1;
		}
	}
	else
	{
		$Chap_ID++;
		$Verse_ID = 1;
	}
}
else
{
	$Verse_ID++;
}
//$Chap, $xml_Books and $Book are xml-nodes

Test script:
---------------
//Code:
if((int)$Verse_ID >= sizeof($Chap->Verse))
{
	if((int)$Chap_ID >= sizeof($Book[($Book_ID-1)]))
	{
		if((int)$Book_ID == sizeof($xml_Books->Book))
		{
			$Book_ID = 1;
			$Chap_ID = 1;
			$Verse_ID = 1;
		}
		else
		{
			$Book_ID++;
			$Chap_ID = 1;
			$Verse_ID = 1;
		}
	}
	else
	{
		$Chap_ID++;
		$Verse_ID = 1;
	}
}
else
{
	$Verse_ID++;
}
//$Chap, $xml_Books and $Book are xml-nodes

Sorry for the double code...
 [2011-10-03 13:47 UTC] keyboard27 dot 10 at gmail dot com
the actual warning comes from the following line:
"if((int)$Chap_ID >= sizeof($Book[($Book_ID-1)]))"

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

is it oke if i would send you the files?
the one is the xml-file which the other file reads and partly displays
it is in dutch, but that shouldn't be a problem

the $Boek_ID var has the value 2, $Hfst_ID is 1 and $Vers_ID is 22, which is Exodus(book #2) 1:22

<?php
//$Verse_ID = 22 (retrieved from database)
//$Chap_ID = 1 (retrieved from database)
//$Book_ID = 2 (retrieved from database)
//$Chap = XML Node
//$Chap->Verse = xml node array(size: 22)
//$Book = xml node array(size: 66)
//$book[($book_id-1)] = xml node array(size: 40)
//$xml_books = xml node
//$xml_books->book = xml node array(size:66)
if((int)$Verse_ID >= sizeof($Chap->Verse))

reproduce script. If you can't minimize the reproduce script,
please make it available for download.
