Issues with my regex in java

Question

Hi guys i am trying to figure out a simple regEx from the given text below:

<b>Name:</b> Photomatix.Pro.v4.0.64bit-FOSI<br />

i basically want to output and store only Photomatix.Pro.v4.0.64bit-FOSI i.e. the actual value thats inside the but when i define it like this:

private static final String REG_NAME = "<b>Name:</b>(.*)<br />";

It actually stores and outputs the whole <b>Name:</b> Photomatix.Pro.v4.0.64bit-FOSI<br />

Any ideas on how i can just extract the value given from the above xml text? cheers in advance

Answer 1

This should work:

  final String REG_NAME = "<b>Name:</b>(.*)<br />";

        String text = "<b>Name:</b> Photomatix.Pro.v4.0.64bit-FOSI<br />";

        Pattern pattern = Pattern.compile(REG_NAME);

        Matcher matcher = pattern.matcher(text);

        if (matcher.find()) {
            System.out.println(matcher.group(1));
        }

(I don't have a Java compiler at hand right now so I cannot verify the answer. Thus this isn't the final answer, but...)

If you really want to do it with regexes, you should take a look at matchers and groups in the Java regex classes.

Answer 3

String r = "/b>(.*)<b";

Pattern p = Pattern.compile( r );
Matcher m = p.matcher( "<b>Name:</b> Photomatix.Pro.v4.0.64bit-FOSI<br />" );

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

well, i don't think it is such a good idea to parse an html using regexes, you should use some html java parsers. if you want to use regular expression though, you can check some examples here: Regular Expressions
