Hello everybody,

Im working in Java and i Want to extract from the follwoing text:

 <tr> 
                            <td width="471" valign="middle"> <div align="justify"><span class="c10_justified"><strong><u>EXTRACTME</a></u></strong><br>
                                Address
                                , telphone:xxxxxx
                                </span></div></td>

                          </tr>

 the text EXTRACTME and the Address,telephone:xxxxxxx

keep in mind that the html has break lines also inside.

Any suggestion?

Regards,

 

Try this:

 

import java.util.regex.*;

public class Test {   
    public static void main(String[] args) {
        String text =
            "some text...\n"+
            "<tr>\n"+
            "  <td width=\"471\" valign=\"middle\"> <div align=\"justify\">"+
            "  <span class=\"c10_justified\"><strong><u>EXTRACTME</a></u></strong><br>\n"+
            "    Address\n"+
            "       , telphone:xxxxxx\n"+
            "  </span></div></td>\n"+
            "\n"+
            "</tr> \n"+
            "some more text...";
        String regex = "(?is)<tr>.*<span.*?>(?:\\s*<.*?>)+(.*?)(?:\\s*<.*?>)+(.*?),(.*?):(.*?)</span>.*?</td>";
        Matcher m = Pattern.compile(regex).matcher(text);
        while(m.find()) {
            System.out.println("group(1) = "+m.group(1).trim());
            System.out.println("group(2) = "+m.group(2).trim());
            System.out.println("group(3) = "+m.group(3).trim());
            System.out.println("group(4) = "+m.group(4).trim());
        }
    }
}

Did you leave text out of the real sample?  It doesn't look formatted as one would expect.  Provide real text (change numbers to 1's and name letters to a's if you need to) to get a working pattern.

The code snippet provided works in the context of this small string but it cannot work as a part of a whole web page.

This is the target URL that i want to parse --> http://www.menuthessaloniki.gr/list_det.asp?area=1&offset=30

Thanks

Could you be more specific? What does "it cannot work" exactly mean? I say it can work.

Perhaps you could post your code here, then I (or someone else) can have a look at it and maybe spot an error.

ok here is the code

<code>    public static void main(String[] args) throws IOException,

   BadLocationException {

URL url = new URL(

"http://www.menuthessaloniki.gr/list_det.asp?area=1&offset=30");

BufferedReader in = new BufferedReader(new InputStreamReader(url

.openStream()));

String str;

StringBuffer buffer = new StringBuffer();

 

while ((str = in.readLine()) != null) {

   buffer.append(str);

}

in.close();

System.out.println(buffer.toString());

str = buffer.toString().replaceAll("\n", " ");

Pattern pattern = null;

pattern = Pattern.compile("(?is)<tr>.*<span.*?>(?:\\s*<.*?>)+(.*?)(?:\\s*<.*?>)+(.*?),(.*?):(.*?)</span>.*?</td>");

Matcher m = pattern.matcher(str);

        if(m.find()) {

            System.out.println("group(1) = "+m.group(1).trim());

            System.out.println("group(2) = "+m.group(2).trim());

            System.out.println("group(3) = "+m.group(3).trim());

            System.out.println("group(4) = "+m.group(4).trim());

        }

    }
