parsing json text
Hi. I have a question about parsing json. I have a book database that I am pulling information from the web. And I can parse all the information after it is gathered. My problem is that some titles do not have ISBN numbers. When these books are parsed I get different text in my ISBN field. Is there a way to make it so if the "ISBN_10" is not found in the json text that the field will be blank? Thanks for any help.
