I have an XML file which is transformed with XSL. Some elements have to be changed, some have to be left as is - specifically, text with entities ", &, ', <, > should be left as is, and in my case " and ' are changed to " and ' accordingly.

Test XML:

<?xml version="1.0" encoding="UTF-8" ?>
<root>
    <element>
        &quot;
        &amp;
        &apos;
        &lt;
        &gt;
    </element>
</root>

transformation file:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
    <xsl:output method="xml" encoding="UTF-8" omit-xml-declaration="no" indent="no" />
    <xsl:template match="element">
        <xsl:copy>
            <xsl:value-of disable-output-escaping="no" select="." />
        </xsl:copy>
    </xsl:template>
</xsl:stylesheet>

result:

<?xml version="1.0" encoding="UTF-8"?>
    <element>
        "
        &amp;
        '
        &lt;
        &gt;
    </element>

desired result:

<?xml version="1.0" encoding="UTF-8"?>
    <element>
        &quot;
        &amp;
        &apos;
        &lt;
        &gt;
    </element>

I have 2 questions:

• why does some of those entities are transformed and other not?
• how can I get a desired result?
