Java Regex Html

Question

Trying to get the result of an html:

private static final String PATTERN = "(ReportSession=)[0-9A-Za-z]{24}";`

...    

Pattern pattern = Pattern.compile(PATTERN);
Matcher matcher = pattern.matcher(".axd?ReportSession=frytm055l51aigbigh5xzrin\u");
if(matcher.find()){
    textView1.setText(matcher.group(1));
}

The output is ReportSession= but I need to get the whole ReportSession=frytm055l51aigbigh5xzrin before the backslash. Any ideas?

You denote groups with parentheses. You have only one inner group, that being (ReportSession=). If you need the whole pattern you can use:

matcher.group();

or

matcher.group(0);

Group zero denotes the entire pattern, so the expression m.group(0) is equivalent to m.group().

Use matcher.group(0) instead of matcher.group(1)
