 * Hi,
 * I had an issue where paragraphs with the ‘&’ character in them where being lost
   if the WP Glossary Hover plugin was trying to insert the tooltip.
 * Tracked it down to the ‘$newNode->appendXML($nodeValue)’ failing in class-tooltip-
   parser.php.
 * This is the solution I came up with:
 * line 217: if ($updateNode)
    { $newNode = $dom->createDocumentFragment(); //error_log(“
   before append: “.$nodeValue); $convertedNodeValue = str_replace(‘&’, ‘&’, $nodeValue);//
   13.12.2014 Duncan M Added otherwise ‘appendXML’ below was consistently failing//
   error_log(“after conversion: “.$convertedNodeValue); //if (FALSE == $newNode-
   >appendXML($nodeValue)) if (FALSE == $newNode->appendXML($convertedNodeValue)){
   error_log(“WP Glossary Hover: appendXML failed, line 227 class-tooltip-parser.
   php”); } $node->parentNode->replaceChild($newNode, $node); }
 * but could be more elegant, and str_replace probably needs to account for more
   characters than just ‘&’… didn’t have time for further investigation sorry!
 * Otherwise, awesome plugin 🙂

 * Sorry, should have included my code correctly:
 *     ```
       if ($updateNode)
       			{
       				$newNode = $dom->createDocumentFragment();
       				//error_log("before append: ".$nodeValue);
       				$convertedNodeValue = str_replace('&', '&', $nodeValue);  //13.12.2014 Duncan M Added otherwise 'appendXML' below was consistently failing
       				//error_log("after conversion: ".$convertedNodeValue);
       				//if (FALSE == $newNode->appendXML($nodeValue))
       				if (FALSE == $newNode->appendXML($convertedNodeValue))
       				{
       					error_log("WP Glossary Hover: appendXML failed, line 227 class-tooltip-parser.php");
       				}
       				$node->parentNode->replaceChild($newNode, $node);
       			}
       ```

 * This issue is now fixed in version 1.2.0. The issue relates to escaping html 
   sepcial characters in the glossary term definition.
