Transforming logdata back to original dataformat

Hi,

i have variable in logdata (DBTABLOG) format, this stores the bytes in hexadecimal format. Cause we have aunicode system, every character is stored in two byte, it looks like this for example:

'003000300036'.

How can i turn this back to

'006'

? So how can i transform this logdata into an xstring or whatever?
