RE: Help with XML error

I don't know what's causing this specific error, but a good way to track it
down would be to log each out from the codes.get[i] loop. At least that way
you would have a place to start looking. One of the elements of that array
looks like it's being left blank.

Subject: Help with XML error

I'm pulling my hair out on this one -- it was working perfectly, and
suddenly it's giving me this error! I'm parsing an XML doc and finding a
certain node based on values that the user has submitted. Here's the line
of code that's triggering the error:

Element thisProduct = (Element)XPath.find("//product[@id='"+ codes.get(i) =
"']", doc);

It's part of a for loop where I'm looping through the array of responses
(codes).

And here's the error:
java.lang.NullPointerException
        at com.caucho.xpath.Pattern.find(Pattern.java:86)
        at com.caucho.xpath.XPath.find(XPath.java:106)

Any help is much appreciated.

Thanks,
Rowan
