 New Comment:

I'm not an (lib)xml expert, but using LIBXML_NOENT as parsing options for the XMLReader aligns
the behaviour:

$xmlreader->xml($xml, null, LIBXML_NOENT);

Description:
------------
In the following test script, the example xml is valid against the supplied schema.  DOMDocument
displays no schema errors as expected, but XMLReader displays a schema violation.  I was expecting
XMLReader to not report any schema violations.


Test script:
---------------
<?php
error_reporting(E_ALL);

$xml = '<user name="a &amp; b"/>';

$schema = '<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
	<xs:element name="user">
		<xs:complexType>
			<xs:attribute name="name" use="required">
				<xs:simpleType>
					<xs:restriction base="xs:string">
						<xs:enumeration value="a &amp; b"/>
					</xs:restriction>
				</xs:simpleType>
			</xs:attribute>
		</xs:complexType>
	</xs:element>
</xs:schema>';

// create temp file with schema
$schema_file = tempnam(sys_get_temp_dir(), '');

file_put_contents($schema_file, $schema);

// test with DOMDocument
$dom = new DOMDocument;
$dom->loadXML($xml);

$dom->schemaValidate($schema_file);

// test with XMLReader
$xmlreader = new XMLReader;
$xmlreader->xml($xml);

$xmlreader->setSchema($schema_file);

while ($xmlreader->read() == true);

$xmlreader->close();

// delete temp file
unlink($schema_file);


Expected result:
----------------
No output

Actual result:
--------------
Warning: XMLReader::read(): Element 'user', attribute 'name': [facet
'enumeration'] The value 'a &#38; b' is not an element of the set {'a
& b'}. in test.php on line 38

Warning: XMLReader::read(): Element 'user', attribute 'name': 'a &#38;
b' is not a valid value of the local atomic type. in test.php on line 38
