Hi,
I need to parse the content of a variable recorded through a barcode. Basically I have a list of ordered elements in the same variable separated by space that I want to re-use in the form after.
I can see that Javarosa only includes the following string functions:
• substr
• string-length
How can I get the equivalent of the x-path functions
• substring-after
and
• substring-before
?
If not, is there a smarter way to do what I need to do?
Thanks!
The problem was located in calculate expression for ${QR1}\nXPath evaluation: cannot handle function 'position' requires either exactly one argument or no arguments.
