Bug description:Provide readonly access to the meta data for the XML stream.
Description:
------------
My start point is the SimpleXMLIterator, but I realise the the any
extension
based upon libxml would have the same issue.
When you are reading a XML stream, file or string, there is no mechanism
available to access the position within the XML unless you implement a 2
pass
mechanism to count the nodes in the first pass and then record your
position in
the second pass.
Using the count() method is available in some of the XML classes, but this
is
still a 2 pass system.
My feature would be to have a mechanism to be able to read the start and
end
position of the element as well as knowing the total size of the file. So
the
progress through the file is still possible (and displayed as a %age rather
than
as an "n of m").
>From what I can see, this is not a minor amount of work. Especially as I
can do
something like ...
$it = new
SimpleXMLIterator('compress.zlib://http://www.site.com/file.xml.gz');
In this instance, there are 2 filelengths. The .gz file from the site as
well as
the streamed/expanded XML file.
Realistically, only the expanded XML file value would be useful in my use
case.
It may be that any/all stream/filters/etc that interact with the data would
need
to be able to report their data.
