#45824 [Bgs]: loadXML moves entity references from attribute value to before element

 ID:               45824
 User updated by:  marc at mongenet dot ch
 Reported By:      marc at mongenet dot ch
 Status:           Bogus
 Bug Type:         DOM XML related
 Operating System: Linux
 PHP Version:      5.2.6
 New Comment:

In the Extensible Markup Language (XML) 1.0 (Fourth Edition) W3C
Recommendation, chapter 4.1 Character and Entity References, it is
written:
"Note that non-validating processors are not obligated to to read and
process entity declarations occurring in parameter entities or in the
external subset; for such documents, the rule that an entity must be
declared is a well-formedness constraint only if standalone='yes'."

What we have in this example is : "Entity 'eacute' is not defined in
Entity" -> i.e. it is not defined in the parsed data. That's because it
is defined in the external subset. Okay, I admit I didn't write an
external subset, but it makes no difference because the XML processor
does not try to read it because I haven't set
$doc->resolveExternals=TRUE.

The XML processor should either stop on a fatal error or produce a
correct DOM (that't a general rule for XML processors). But producing a
wrong DOM is a no-no. BTW, if the é entity reference appears in
the text instead of an attribute value, then the DOM is correctly built.

You should read the warning, it produces:

Warning: DOMDocument::loadXML(): Entity 'eacute' not defined in Entity,

line: 2 in /Users/chregu/tmp/foo.php on line 6

eacute is not a entity which is defined by default (there are only 5 of

them)

Description:
------------
When an attribute value contains an entity reference (like
a="é"), loadXML() moves this entity out of the attribute, just
before the owner element.

Reproduce code:
---------------
$doc = new DOMDocument();
$xml = '<!DOCTYPE e PUBLIC "1" "2">'."\n". # DOCTYPE just to appear
well-formed
       '<e><e a="&eacute;"/></e>'."\n";
$doc->loadXML($xml);
echo '<pre>', htmlspecialchars($doc->saveXML()), '</pre>';


Expected result:
----------------
<?xml version="1.0"?>
<!DOCTYPE e PUBLIC "1" "2">
<e><e a="&eacute;"/></e>


Actual result:
--------------
<?xml version="1.0"?>
<!DOCTYPE e PUBLIC "1" "2">
<e>&eacute;<e a=""/></e>
