< in addHTML

[sleker78]

Hi,

Great application - thanks.
There is a problem when you have < in string:

$html='<p>something &lt; something </p>;
\PhpOffice\PhpWord\Shared\Html::addHtml($section, $html);

It'll break the xml structure for docs. Possible solution is to change addHTML method:

 // Load DOM
        $dom = new \DOMDocument();
        $dom->preserveWhiteSpace = true;
        $dom->loadXML($html,LIBXML_NOCDATA);

With this replacement user can send <![CDATA[_lt_]]> instead of < like this:

$html='<p>something <![CDATA[_lt_]]> something </p>;
\PhpOffice\PhpWord\Shared\Html::addHtml($section, $html);

and it'll work ok.

Maybe there is some better solution but this will work for now.

Thanks
