    Is this something I should worry about?

  • can you tell me how to fix this please

    @khuramk:

    I’ve not had the time to seriously debug it. At the moment, the only thing I can tell you is the following:

    as far as I understand, the content of the variable $xmlSource at line 1649 can be a valid XML string or false. I suppose it is not false because if you’d directly pass false you’d get another kind of error (DOMDocument::loadXML(): Empty string supplied as input). Since $html can’t be false, the error doesn’t derive from $html variable being false. There could be something wrong in the content of the $html variable.

    @khuramk :

    I temporarily solved this way, that is, this way I see no more warnings in DEBUG.log: anyway, I suggest you to WAIT for an update of the plugin and NOT apply my patch (I’m actually not sure if there can be any consequences):

    if ($html) {
            
			$xmlSource = ob_get_clean();

			/* temporary patch, just to silence the error */
			// if $xmlSource is ISO-8859-1, convert it to UTF-8
			// else I take for granted it is UTF-8
			$xm = mb_detect_encoding($xmlSource, 'ISO-8859-1', true) ? iconv('ISO-8859-1', 'UTF-8//TRANSLIT', $xmlSource) : $xmlSource;
			
			// if the XML string is well formed
			if (simplexml_load_string($xm) !== false) {

				// Load the XML source
				$xml = new DOMDocument;
				$xml->loadXML($xmlSource);

				$xsl = new DOMDocument;
				$xsl->load($this->GetPluginPath() . "sitemap.xsl");

				// Configure the transformer
				$proc = new XSLTProcessor;
				$proc->importStyleSheet($xsl); // attach the xsl rules

				$domTranObj = $proc->transformToDoc($xml);

				// this will also output doctype and comments at top level
				foreach ($domTranObj->childNodes as $node) echo $domTranObj->saveXML($node) . "\n";
			}
		}

		if($packed) ob_end_flush();
		$this->isActive = false;
		exit;
	}
