Summary: DOMDocument::baseURI parsing is out of whack
Status: Not a bug
Type: Bug

I submitted a couple of related feature requests:
Request #65364 - In doc not loaded from a URL, baseURI should still be a real
URI
Request #65365 - Allow defining baseURI of doc not loaded directly from URL

Please take care that PHP's DOMDocument does not offer the DOM CORE Level 3
feature at all. So whatever the specs of that DOM Core Level say, nothing -
absolutely nothing - allows to draw the conclusion that this (perhaps by
accident
same named property) is an implementation of DOM Core Level 3.
PHP's DOMDocument has only DOM Core Level 1 feature which does not cover this
property.
All references to XML Infoset in this ticket are therefore completely bogus.

A test case which illustrates that the baseURI parsing is working correctly now
(at least in PHP 5.3.15):
<?php
$doc =
DOMDocument::load('http://www.w3.org/2001/sw/grddl-wg/td/inline-rdf6.xml');
var_dump($doc->baseURI); //
"http://www.w3.org/2001/sw/grddl-wg/td/inline-rdf6.xml";
var_dump($doc->documentElement->baseURI); // "http://wwww.example.org/";
As http://www.w3.org/TR/xmlbase/ describes, the base URI of a document entity
is the URI used to retrieve the document entity. The base URI of an element
(including the document element) is
detected by various rules, starting with the xml:base attribute on the element.

:S I hate being pushy / argumentitive, sorry if its coming across that way.
RFC 2396 is "Uniform Resource Identifiers (URI): Generic Syntax"
Section 5.1. is "Establishing a Base URI" describes what I've been trying to
say, probably a little clearer.
XML Base spec @ http://www.w3.org/TR/xmlbase/#rfc2396 says:
Determine a baseURI:
1. The base URI is embedded in the document's content.
2. The base URI is that of the encapsulating entity (message, document, or
none).
3. The base URI is the URI used to retrieve the entity.
4. The base URI is defined by the context of the application.
> This is not just how it is implemented in PHP as the other major DOM parsers
> implement it the same way
... and that's why the xml:base GRDDL tests were written - to clarify correct
behaviour / check implementations.

still bogus as what you are describing pertains to GRDDL only not DOM,
so when working with GRDDL and DOm you need to check base uri of the
document element, not the DOMDocument.
DOM determines base uri using the xml base spec.
"The base URI of a document entity or an external entity is determined
by RFC 2396 rules, namely, that the base URI is the URI used to retrieve
the document entity or external entity."
This is not just how it is implemented in PHP as the other major DOM
parsers implement it the same way,

See http://www.w3.org/TR/grddl/#base_misc &
http://www.apps.ietf.org/rfc/rfc3986.html#sec-5.1
The way to determine baseURI is:
1. Look for it on the root document element (HTML - <base>, XML - <foo
xml:base="">
2. Couldn't find that? Use the URL we retrieved the document with
* And make sure we follow redirects!
3. Couldn't find that? Application specific (but we don't really have a
setBaseURI())
So, condition #1 is broken in 5.2.5 when you do:
<?php
$doc =
DOMDocument::load('http://www.w3.org/2001/sw/grddl-wg/td/inline-rdf6.xml');
var_dump($doc->baseURI); //Expected http://wwww.example.org/
produces:
string(53) "http://www.w3.org/2001/sw/grddl-wg/td/inline-rdf6.xml";
