Comment 2 for bug 1666195

I created a second xml which looks like this:

<root>
 <level1>
  <child1><child2><child3></child3></child2></child1>
  <child4></child4><child5></child5><child6></child6>
 </level1>
        ...
 <level1>
  <child1><child2><child3></child3></child2></child1>
  <child4></child4><child5></child5><child6></child6>
 </level1>
</root>

childs = root.xpath('.//child1')

Starting with the 16384th child1 element it won't return the right sourceline:

>>> c1[16382].sourceline
65531
>>> c1[16383].sourceline
65535
>>> c1[16384].sourceline
65535
>>> c1[16385].sourceline
65535
>>> c1[16386].sourceline
65535
>>> c1[-1].sourceline
65535
