Question

I am trying to find some rates in a table using Regular Expressions that I am reading into a string from HTML. Here is an example:

<td>Euro</td>
<td class='rtRates'><a href='/graph/?from=USD&amp;to=EUR'>0.772199</a></td>
<td class='rtRates'><a href='/graph/?from=EUR&amp;to=USD'>1.295003</a></td>

I am trying to find the numbers contained in the above string. They constantly change so it can’t be a hard-coded number search.

I’ve tried using something similar to this: to=EUR’>(…)

but it only returns the 0.7, not the rest. Any help is appreciated!

EDIT: some code was requested, so here it is

      String re2="to=EUR'>(...)";   // Float 1

    Pattern p = Pattern.compile(re2,Pattern.CASE_INSENSITIVE | Pattern.DOTALL);
    Matcher m = p.matcher(webData);

    if (m.find())
    {
        String float1=m.group(1);
        System.out.print("("+float1.toString()+")"+"\n");
    }

You can use this expression for quick and dirty searches:

EUR'>([^<]*)<

This is not ideal, though: using an HTML or an XHTML parser is a much better solution, because it is much more powerful and robust than any regex-based solution.
