Java Split Text to 2 Arrays

Question

I have following text:

    <option value="{0}">hello1</option>
    <option value="{1}">hello2</option>
    <option value="{2}">hello3</option>
    <option value="{3}">hello4</option>
    <option value="{4}">hello5</option>
    <option value="{5}">hello6</option>
    <option value="{6}">hello7</option>
    <option value="{7}">hello8</option>

All above is in one String.

I have 2 Arrays:

valueArray;
nameArray;

So, any tip on how to get the helloX into nameArray and get all value into valueArray?

You need to use an XMLPullParser, and then parse the option start tag for your value. — hwrdprkns

You can find the position of > using start =str.indexof(">");

also position of </ using stop=str.indexof("</");

then get string str = str.subString(start,stop);

you will get helloX...

replace your { bracket and } bracket with & #123; ** and **& #125;

I find this type of solution to be clunky and error prone. It will quickly fail with <option value="<{0}>">hello0</option>.

Use a regex and populate the arrays. Here is a small test program I wrote:

public static void main(String [] args) {
    Pattern p = Pattern.compile("<option value=\"(.*?)\">(.*?)</option>");
    String line = "<option value=\"{1}\">hello0</option>";
    Matcher m = p.matcher(line);
    while (m.find()) {
        String value = m.group(1);
        String name = m.group(2);
        System.out.println(value);
        System.out.println(name);
        // Now add to your arrays
    }
}

I would not use this as a standard method for parsing a complicated xml file. Use an xml parser if this is the case.

Hmm, m.matches is never true...Any idea?

Well, your code works but it won't find if I replace line with my string

Nate Over a year ago

Can you provide the actual string that you're trying to parse?

Nate Over a year ago

In that case, use m.find() instead of m.matches(). If there may exist multiple matches per line of text, call m.find() multiple times until it returns false.
