Java reg exp question

[laredotornado]

Hi,

I'm using Java 1.5. How do I find all strings matching a particular
pattern in a larger string? For example, I have HTML page source, and
I want to find all the names of the checkboxes where I'm guaranteed
the checkboxes will appear on the page like so ...

<input type="checkbox" value="true"
name="invoicingReport:invoicingTable:1:_idJsp17"/>

Thanks for your help, - Dave

Compile your Pattern, get a Matcher from it, and call the
Matcher's find() method in a loop until it returns false.

Pattern patt = Pattern.compile("whatever", options);
Matcher match = patt.matcher(theString);
while (match.find()) {
System.out.println(match.group());
// or use match.start(), match.end()
}
