hi neil,
this is indeed a very helpful piece of code and advice.. thank you so much!
if this
took you 30 minutes to write, it would have taken me a day to learn XML, and
start writing! this code looks complicated for a young programmer like me
;p.. i'll need time to read up on XML and get back to you again if i have
queries about the codes..
you really helped cut my learning curve in XML and at the same time solve my
client-server problem.. may you be blessed just like how your codes have
blessed me! :o)
thanx lots,
Hwee Hwee
