I have the following source code taken from another website.
I need to take the value "DOLARTODAY" only the numerical value of that same web directly so that it is updated automatically. That is, I only get the BsF value, omitting the abbreviation BsF. The example of what I occupy is below. I mean I WANT to take only the numbers in the numerical field FILA DOLARTODAY and then multiply it or just make a kind of IFRAME that allows me to take the numeric value and multiply by the value obtained.
