Bug description: getAttribute() incorrectly de-references entities
Description:
------------
When using getAttribute to get the value of an attribute
that contains an XML entity (eg. ®) the returned value
is neither the actual character that is being represented
nor the characters that make up the entity '&' '#' '1'
'7'
'4'. Instead there are two characters that are returned, A
circumflex (Ã) and, in this example, the registered
trademark symbol (®).
'./configure' '--prefix=/opt/php5' '--with-mysql'
'--with-apxs2=/usr/sbin/apxs2' '--with-zlib' '--with-expat'
'--enable-sigchild' '--with-openssl' '--enable-shared'
'--enable-soap' '--with-gd' '--enable-mbstring'
'--with-pgsql' '--with-imap=shared,/usr/lib'
'--with-imap-ssl=no' '--with-gd'
'--with-jpeg-dir=/usr/include' '--with-ldap' '--with-xsl'
'--enable-memory-limit' '--enable-debug'
'--with-libxml-dir=/usr'
Reproduce code:
---------------
ent.php:
$dom = new DomDocument();
$dom->substituteEntities = true;
$dom->resolveExternals = true;
$dom->load('ent.xml');
$dom->substituteEntities = true;
$dom->resolveExternals = true;
echo $dom->saveXml();
$list = $dom->getElementsByTagName('bar');
$node = $list->item(0);
echo "\n===\n Attribute 'test' of node 'bar': ";
echo $node->getAttribute("test");
echo "\n===\n Attribute 'test' of node 'bar' with htmlentities:
";
echo htmlentities($node->getAttribute("test"));
echo "\n===\n";
ent.xml:
<?xml version="1.0"?>
<!DOCTYPE foo [
<!ENTITY reg "®">
]>
<foo>
<bar test="®">®</bar>
</foo>
Expected result:
----------------
<?xml version="1.0"?>
<!DOCTYPE foo [
<!ENTITY reg "®">
]>
<foo>
<bar test="®">®</bar>
</foo>
===
Attribute 'test' of node 'bar': ®
===
Attribute 'test' of node 'bar' with htmlentities:
&#174;
===
Actual result:
--------------
<?xml version="1.0"?>
<!DOCTYPE foo [
<!ENTITY reg "®">
]>
<foo>
<bar test="®">®</bar>
</foo>
===
Attribute 'test' of node 'bar': ®
===
Attribute 'test' of node 'bar' with htmlentities:
®
