Using foreach with xml results

[rossmurphy]

Hi,

 

I make calls to an api and receive xml response. I then use a froeach to go through data. I do this on nearly every page on my site. Often no data is returned by the api for whatever valid reason, but this then causes errors with the foreach loops. What is the best way of getting over this?

 

Would it be to do a simple if else check before the foreach? has anyone come up with other solutions or had this problem?

 

 

Thanks in advance.
