The target site might not be organized enough to stick the Price value
in a meta header. If every page contains text in the format
Price: $19.95, Data From Field can key in on that.
REX Search - Price:=\space+\$\P=[0-9\.]+
Replace - (Empty)
From Field - Text
From Meta Field - (Empty)
To Field - Price
Notice that we use the field Text as the source, not
HTML. By operating on the formatted text instead of the raw
HTML source, it allows proper operation even if the HTML source uses
things like Price: <b>$19.95</b> or
<td>Price:</td><td>$19.95</td>.
