Web utilization and data processing in java

Question

I am writing a web-clip program to extract stock quotes from yahoo finance, google finance or nasdaq. I can get an html element containing stock prices, but I only need the dollar value from the result. For example, the sample output is as follows:

I use the image here because when I posted the actual html, only dollar amounts appeared (desired results), the objects and html tags disappeared. Here is my code    I am not very familiar with regEx, but I tried, but no luck. How can I extract only the dollar amount from the issue?

Answer 1

Try using java.util.regex.Matcherand java.util.regex.Pattern:

String pattern = "<td>\\$&.+;(\\d{1,4}\\.\\d{2})&";
Pattern p = Pattern.compile(pattern);
Matcher m = p.matcher(inputLine);

if (m.find( )) {
     System.out.println("Price: $" + m.group(1) );
}

Result:

: $130,27...
