Question

I’m trying to pull out sub-string from a string using java.Util.Scan

The sub-string is between “<TD class=MoreB align=center>” and “</TD>” in the original string

This is the code:

public static String pullStringOut(String str)
{
    String stringer = null;

    Scanner scanner = new Scanner(str);
    scanner.findInLine("<TD class=MoreB align=center>");

    while (scanner.hasNext() && scanner.next() != "</TD>")
    {
        stringer+= " " + (scanner.next());
    }

    return stringer;
}

but it’s not working well.

From the original string:

“<TD class=MoreB align=center>TextTextTextText</TD></TR></TABLE> }“

I get the following result:

“TextTextTextText</TD></TR></TABLE> }“

Instead of the expected

“TextTextTextText”

You can use a Regex Expresssion.

Something like :

    Pattern p = Pattern.compile("/\<TD class=MoreB align=center>(.*)\<\/td\>/"); 
Matcher m = p.matcher(str); 
while(m.find()) { 

  //do whatever you want here
 }
