I assume you want to read a variable value (the car price) in a line where
the word "car" appears.
If the line in the HTML keeps constant, and only the car price changes,
you could use:
lynx -dump www.abc.com/index.html | awk '{if (match($0, /car/)) print $7}'
where the magic number 7 refers to the 7th record (100, i.e car price) in
a line that matches car.
But thats quite dodgy, and falls over if the word car appears in other
lines in the HTML document, or if something else changes.
You can read the lines and split them up with a "while" loop, and using
"read".
I have done that analyzing a line of a httpd log file in a bash script on
my Web page (see footer, go "scripting", "log files").
That's cumbersome, but you check each record separately, and it's very
flexible.
