Hi friends,

Please, see the attachment and examine a code I have provide. The 
problem is, I want fetch data from <H2>Comments</H2> until the first 
</TD> occurrence , but with my code data fetchind until the last </TD> 
in htmlData variable, but that is not what I want. So question is, what 
is my mistake?

Thanks in advance.
