How do I make an Array from jSoup Elements? (java)

Question

How do I get the values in a piece of Html (values="valueIWant"), and have them in an Array ? I tried the following, but that didn't work:

HttpEntity entity5 = response5.getEntity();
    String defaultString = EntityUtils.toString(entity5);
    Document defaultDoc = Jsoup.parse(defaultString);                   
    Elements values = defaultDoc.getElementsByAttribute("value"); //DropDownList Values
    String s[] = {""};
    for(int a=0; a<values.size(); a++){
        s[a] = values.get(a).toString();
    }
    return s;

So anyone got an answer? thanks. (Btw, i use Jsoup)

"that did not work"... In what way? Did you get compilation error, runtime exception, results did not meet your expectations? — Olaf

First of all: is your HTML parsed correctly? Can you provide the contents of defaultString? Is defaultDoc valid is there a problem with file encodings perhaps?

Assuming getElementsByAttribute actually returns some objects —note that you have a typo, value instead of values— you're currently populating the array with the descriptions of all Element-objects, not the values of the attribute. Try something like the following:

int i = 0;
String s[] = new String[values.size()];
for(Element el : values){
    s[i++] = el.attr("values");
}

I now changed my code to ----Elements values = defaultDoc.getElementsByTag("option"); s[i++] = el.attr("value");---- I thought that it was "value" instead of "values", since <option value="VALUEIWANT"> says "value" (wich I wanted to get). Correct me if i'm wrong pls.

Then it's value indeed, however in your question you talk about values. However does your code work now? It should or other things may go wrong.
