I have a scenario where I have to use xpath to identify the element . However I want the xpath to be dynamic and the parameter that I pass to xpath should be based on buffer that I stored as part of the test run.
Is it possible to give buffer value in xpath ?
Yes, it is possible. You must put the buffer name in quotes. Here how I use it to iterate over Number for div[Number]:
"id('table')/div["{B[Number]}"]"
^-----------^ < note the quotes
Have you tried with {B[your_buffer_name]} within your xpath? I never tried using a buffer in a property but that may work.
I would also suggest finding other ways of uniquely identifying your elements. IMHO xpath is rather prone to being unstable. Any change in the page structure will likely break it.
