Issue with some documents when the ${ part is splited

[edyan]

Hi,

If you have a document where some variables are splited in the XML in parts, the regex doesn't work. I have done these changes to the code:

• getVariablesForPart =>

changed

    preg_match_all('/\$\{(.*?)}/i', $documentPartXML, $matches);

to

    preg_match_all('/\$\{(.*?)}/i', strip_tags($documentPartXML), $matches);

That makes the search faster and gives the warranty to find the variables

• setValueForPart

Changed to pattern and exit if no match

        $pattern = '/\$((.|\n)*?)\{((.|\n)*?)\}/m';
        preg_match_all($pattern, $documentPartXML, $matches);
        if (empty($matches[0])) {
            return $documentPartXML;
        }
