You are after a string paser or substring methods... this is fairly standard for any developer. What code are you using currently?

Basically you load the whole html data into a single string and then strip it down to only the conent you need. This can be done with split methods that will split a string into an array or other means... this subject has already been covered multiple times...

You can extract data from HTML using Regular Expressions.

Use the following code to extract data between your span tags:

String value = regexMatch(HTML, "<span class=\"linha\">(.+?)</span>");

Here is the function:

public static String regexMatch(String source, String compilePattern) {
    // Compile regex pattern
    Pattern regexPattern = pattern.compile(compilePattern);

    // Create a matcher against input
    Matcher regexMatcher = regexPattern.matcher(source);

    // Find first match
    if (regexMatcher.find()) {
        // Return first group
        return RegexMatcher.group(1);
    }

    // Return empty string if no match
    return "";
}
