Handle XML parsing errors in TimelineJS::extractUrl()

>>> [!note] Migrated issue   Reported by: [ownage](https://www.drupal.org/user/1361310) >>> For reasons unknown, after a migration to another domain on the same server (same PHP version and everything), I started receiving this warning 4 times on my Timeline embedded: <blockquote>Warning: DOMDocument::loadHTML(): htmlParseEntityRef: expecting ';' in Entity, line: 1 in views_timelinejs_plugin_style_timelinejs->extract_url() (line 596 of /sites/all/modules/views_timelinejs/views_timelinejs_plugin_style_timelinejs.inc). </blockquote> I first tried making sure any of my special fields with URL's didn't have any special characters, e.g. <code>&</code> vs. <code>&amp;</code> but that didn't seem to fix it. I was able to evaporate the warning by adding two lines into this views_timelinejs_plugin_style_timelinejs.inc function: <div class="codeblock"> <pre><?php   /**    * Searches a string for HTML attributes that contain URLs and returns them.    *    * This will search a string which is presumed to contain HTML for anchor or    * image tags.  It will return the href or src attribute of the first one it    * finds.    *    * This is basically special handling for core Image fields.  There is no    * built-in field formatter for outputting a raw URL from an image.  This    * method allows image fields to "just work" as sources for TimelineJS media    * and background image URLs.  Anchor tag handling was added for people who    * forget to output link fields as plain text URLs.    *    * @param string $html    *   A string that contains HTML.    *    * @return string    *   A URL if one was found in the input string, the original string if not.    */   protected function extract_url($html) {     if (!empty($html)) {       $document = new DOMDocument();       $internalErrors = libxml_use_internal_errors(true); // <------ #1       $document->loadHTML($html);       libxml_use_internal_errors($internalErrors); // <------- #2       // Check for anchor tags.       $anchor_tags = $document->getElementsByTagName('a');       if ($anchor_tags->length) {         return $anchor_tags->item(0)->getAttribute('href');       }       // Check for image tags.       $image_tags = $document->getElementsByTagName('img');       if ($image_tags->length) {         return $image_tags->item(0)->getAttribute('src');       }     }     return $html;   } ?></pre></div> Source of the solution at this StackOverflow post: <a href="http://stackoverflow.com/questions/1685277">http://stackoverflow.com/questions/1685277</a> Again, I don't know why this error started happening but wanted to report this in case it would be useful for others, or if it would possibly help to be committed.
