I have an application that loads several xml files, and then outputs some of the data from the file. The problem is that every once in a while, the service that provides the xml file does maintenance (or has an error in the file), and my application gives a "Fatal error: Call to a member function children() on a non-object in..." I would like to handle the error differently, by displaying "unavailable" instead of the error. I know that this is usually not the appropriate way of handling errors, because there is a reason for a fatal error. Any ideas on how to appropriately handle this error? // Node 217 (GGB) $xml = simplexml_load_file("http://services.my511.org/traffic/API_KEY_REMOVED_FOR_EXAMPLE"); foreach($xml->children() as $traveltime) { $ggb = "$traveltime->currentTravelTime"; } echo "GGB:" , $ggb , " Minutes";

I'm working through some code to display a tumblr blog on a website. Each of Tumblr's post types are easy enough to get to... <ul id="reblog"> <? foreach ($xml->posts->post as $post) { ?> <li> <? // REGULAR POSTS if ($post['type'] == "regular" ){ echo "This is a regular post"; } // PHOTO POSTS if ($post['type'] == "photo" ){ echo "This is a photo post"; } // LINK POSTS if ($post['type'] == "link" ){ echo "This is a link post"; } // AUDIO POSTS if ($post['type'] == "audio" ){ echo "This is an audio post"; } ?> </li> <? } ?> </ul> What I'm trying to do is to check and see if certain tags are used on a post, and the based on that I'll be formatting the entry a little different. I can list all of the tags, but I'm stumped on how to check the existence of a certain tag in $post->{'tag'} $xml = simplexml_load_file('http://applesold.com/assets/cache/tumblrposts.txt'); <ul id="reblog"> <? foreach ($xml->posts->post as $post) { ?> <li> <? // REGULAR POSTS if ($post['type'] == "regular" ){ echo "type of post: regular<br>"; // THIS DOESN'T WORK -- if ($post->{'tag'} == "infographic") { echo "INFOGRAPHIC"; } else { echo "non-INFOGRAPHIC"; } } ?> </li> <? } ?> </ul>
