 |
|
hello all
i have been trying to find a way to have vds search a php web page for a string once its found pop open a window...my questions is can i have it search on line or do i have to have it save then page first then search it?
here is the code i'am trying to find
| Code: |
.<BR>The current number of free downloads is: <font color=black><font color=red>427<font color=black><font face='Arial' size='2'> |
note what i'am trying to watch is the "427" number i would like to have it pop open a window when that number is below 200
thanks

It doesn't really matter if you save the page to disk or not, but what you
need to do is get the page, then do something like
the following:
| Code: | %%string = ".<BR>The current number of free downloads is: <font color=black><font color=red>427<font color=black><font face='Arial' size='2'>"
info @substr(%%string,81,83) |
That will give you the number in place of 427, provided that the number
of characters before it doesn't change.
Take a look in the help file for more string processing functions.

Here's a lil trick that will work as long as the : stays in the sentence before the number:
| Code: |
REM GT-HTMLStrip Care of Garrett
%A = ".<BR>The current number of free downloads is: <font color=black><font color=red>427<font color=black><font face='Arial' size='2'>"
GOSUB GT-HTMLStrip
OPTION FIELDSEP,":"
PARSE "%%words;%%num",%A
info %%num
exit
:GT-HTMLStrip
repeat
if @greater(@pos(<,%A),0)
%b = @pos(<,%A)
%c = @pos(>,%A)
if @equal(%B,1)
%d =
else
%d = @substr(%A,1,@fsub(%B,1))
end
%e = @substr(%A,@sum(%C,1),@len(%A))
%a = %D%E
end
until @not(@greater(@pos(<,%A),0))
exit

Side-note: Aren't the Code tags NOT supposed to wrap?

I believe this should work...
| Code: |
%%html = PUT THE CONTENTS OF YOUR WEBSITE HERE
%%before = .<BR>The current number of free downloads is: <font color=black><font color=red>
%%after = <font color=black><font face='Arial' size='2'>
info @strbetween(%%html,%%before,%%after)
exit
:strbetween
exit @substr(%1,@sum(@pos(%2,%1),@len(%2)),@pred(@pos(%3,%1))) |
