    Hello everybody,

    I'm writing a program in java and I have a problem. I want to read a string from tags. Like this: <body> Some text </body>. Could anyone have an idea how to solve it?

    Thanks.

    Take a look here for a free parsers:

    Open Source HTML Parsers in Java

    I cannot know which one will fulfill your needs,
    but important thing is that parser is smart enough to clean
    all non-tag content, so you can easily get what's inside of tags.

    good luck

    for example:
    <body>
    text text
    word1 word2
    sentence text word
    </body>
    if i have text like this between tags the result is: "text text word1 word2 sentence text word" if i use stringtokenizer I get
    text
    text
    word1
    word2
    sentence
    text
    word

    what i need is that when read that text between tags and I want to get it as it was before. The result I need is:
    text text
    word1 word2
    sentence text word

    I tried using parser, but it does not works like i need
    Please help

    This unfortunately doesn't tell us much.

    I found a solution
    Here it is, maybe you need it someday:

    public void getTextBetweenBodyTags() throws IOException{
    ArrayList<String> textBetweenBody = new ArrayList<String>();
    int findBody = 0;
    File file = new File(inPutfile);
    BufferedReader reader = null;
    String line;
    try{
    reader = new BufferedReader(new FileReader(file));
    while ((line = reader.readLine()) != null){
    if (line.equals("</body>")){
    findBody = 0;
    }
    if (findBody == 1){
    textBetweenBody.add(line);
    }
    if (line.equals("<body>")){
    findBody = 1;
    }
    }
    } catch (FileNotFoundException e){
    e.printStackTrace();
    }
    }

    }
    }
    } catch (FileNotFoundException e){
    e.printStackTrace();
    }
    }
    but dont you think this only good when the info is in between the body tags.
    if theres any other tags for font or font size or anything else. it would be not so useful.
