After the XML-into, Text will be a space, Test will be a zero and Temp will be ‘AAA’.

That’s what you have after XML-INTO. But what was the value of [Temp] before XML-INTO?

Because the data structure is part of your program, you are responsible for setting an intial value of [Temp] before you run XML-INTO. If you set it to *LOVAL for example, you can test to see if it still has *LOVAL after you run XML-INTO. If the value has changed, you know that you received a new value.

I’m not sure how to clarify that.

I need to know that I got the element so I know what to do to the field in my database file. I was hoping for an option in xml-into that would tell me that I got a value in the field, or didn’t get a value in the field.
My data structure has 3 elements: Text 1A, Test 1S0 and Temp 3A.
My file contains Txt = ‘X’, Tst = 9 and Tmp = ’123′.
My doc just has AAA.
After the XML-into, Text will be a space, Test will be a zero and Temp will be ‘AAA’.
I don’t want to change Txt from ‘X’ to a space nor Tst from 9 to zero, I only want to change Tmp from ’123′ to ‘AAA’.

Is there a way to do that with xml-into? The documentation for allowmissing=yes tells you how to tell if an element was missing, and even shows an example of coding to detect a missing element. The way to tell if an element was not missing is simply the opposite of an element that was missing. Tom
