Help class to filter HTML code by FredrikN
Posted: 22 Apr 03


Lets say you downloaded an html page from www.thegate.nu/uptime.php.

Then the output will look like

<title>Uptime www.thegate.nu</title>;
<body text="#FFFFFF" bgcolor="#000000">

<p align="center"><font size="4" face="System"> 18:06:38 up 28 days,  2:09,  0 u
sers,  load average: 0.00, 0.01, 0.00


If you don't want all tags then you can make some filter
to do the work for you.

Well, the solution to this problem is to make a HTMLFilter class.

If you don't have time to do it yourself or just don't know how then you can use this class.

The HTMLFilter class has 2 constructors, one takes an String  and the other takes an StringBuffer

Eg. (where str is some HTML code)

HTMLFilter f = new HTMLFilter();

The output from www.thegate.nu/uptime.php will
look like

Uptime www.thegate.nu 18:40:30 up 28 days,  2:43,  0 users,  load average: 0.00, 0.01, 0.00

public class HTMLFilter

    public String filter(StringBuffer input)
        return new String(privateHelpMethod(new String(input)));    
    public String filter(String input)
        return new String(privateHelpMethod(input));    
    private  String privateHelpMethod(String input)
        StringBuffer clean = new StringBuffer();
        boolean add = true;
        for(int i = 0 ; i < input.length() ; i++)
            if(input.charAt(i) == '<')
                add = false;
            else if(input.charAt(i) == '>')
                add = true;    
            else if(add == true)
        return new String(clean);


Easy but still very useful
