PHP XSLTProcessor Compilation error

Question

Cannot make transformation with stylesheet, which has entity inside xsl:text node. I've got no errors and empty output if I put &some; outside xsl:text node.

test.php

$xml = new DOMDocument;
$xml->load('test.xml');

$xsl = new DOMDocument;
$xsl->load('test.xsl');

$proc = new XSLTProcessor;
$proc->importStyleSheet($xsl);

echo $proc->transformToXML($xml);

test.xml

<?xml version="1.0" ?>
<test>123</test>

test.xsl

<?xml version="1.0" encoding="utf-8"?>

<!DOCTYPE xsl:stylesheet [ <!ENTITY some "22323"> ]>
<xsl:stylesheet version="1.0"
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform">


    <xsl:output method="text" />

    <xsl:template match="/">
        <xsl:text>&some;</xsl:text>
    </xsl:template>

</xsl:stylesheet>

Got error:

Warning: XSLTProcessor::importStylesheet(): xsltParseTemplateContent: xslt:text content problem in /Users/stexe/Repos/umi.cms.2/test.php on line 13

Os X, PHP 5.4.45 (Homebrew)

PHP info:

libxml2 Version => 2.9.5
ibxslt Version => 1.1.29
libxslt compiled against libxml Version => 2.9.4

PHP and XSLT tagged in same question? Be still my heart...Anyways, the ampersand, &, is a special XML entity and its symbol cannot standalone. And do note XML entities are not the same as HTML entities. — Parfait

Try setting

$xsl = new DOMDocument;
$xsl->substituteEntities = TRUE;

before the load call.
