SimpleXML, checking if xml file has any contents, if not get default xml file

[D-Dayve]

Hello Everyone,

I have been searching and trying to figure out how to do this all day everything i tried seemed not to work.

I am trying to gather XML file contents via simplexml. My XML files are dynamic, as in it has a keyword and it will pull the xml file according to the keyword. However not all keywords return valid entries. But the url will exist it just wont have any of the item fields but it does have a field that will say <totalResultCount>0</totalResultCount>

Now what i am wanting to do is for it to check if fields exist(or if totalresultcount is 0) if they dont exist it would show a default feed. I have tried a few different things and nothing seems to work. Here is what my most recent code looked like.

 <?php
if(!file_exists("xmlfile.php?keywords=".$page_artistu.""))
{
  $tfeed = "xmlfile.php?keywords=".$page_artistu."";
}
else {
  $tfeed = "xmlfile.php?keywords=default";
}

$lfeed = @simplexml_load_file("$tfeed");    

So pretty much if the xmlfile with the dynamic keyword returns actual fields than use it if theres no fields or if for the field totalResultCount 0 it would show the default feed.

Obviously the file exists everytime it just doenst have entries, so if anyone has any suggestions or ideas i am all ears.

Thank You,
Dave

I think you going about it the wrong way. I can't imagine there is any way to name a file "xmlfile.php?keywords=mykeyword" without causing all sorts of problems.

I suspect xmlfile.php loads and then it checks what the value of "$_GET['keywords']" is and then loads the appropriate code. So

if ((isset($_GET['keywords']) && ($_GET['keywords'] != 'mykeyword')) {
// include default code here;
}
else {
// run code code for $_GET['keywords'] here
}

That is very generic but it gives you a general idea. Just use xmlfile.php to check the value of $_GET['keywords'] and then based on your criteria load the appropriate content.
