Here is the Example for correlation.

In the Below Script:
web_reg_save_param( Queries1
LB/IC src ElinkTop.asp?querys
RB/IC >
NotFound ERROR
Search All
LAST);


Queries1 is Cor Name
LB/IC Left Bound and Igonre Case
RB/IC Left Bound and Igonre Case
Not Found If the LB Rb is not found in u r script then throughs Error
Search All means searchs all the the body... etc
one more thing is Ord is Ordinal if the value is 2 it checks the second found tag.
All the CorName should be Unique.

web_reg_save_param is a registration type function. It registers a request to find and save a text string within the Web page that was retrieved. The operation is performed only after executing the next action function such as web_url.

Some times the LB RB is exists and found corectly also throguhs error because of memory. To reduce above problem u should use
web_set_max_html_param_len( VALUE );
Example Value 50000 as per u r application.

This is very imp function and useful feture in LR..
Thanks and Regards
