Extract substring from string Android

Question

I have string like this:

<a hidden="true" href="xxx" class=" zt-uie-session      </a>

How to extract href value in Android? It's string, not some object.

Is hidden and class always going to be there? Showing just one string isn't enough. Please show more examples of how the string can change, what format is the string in. — Sweeper

Please don´t use any kind of String functionallity.. If this tag isn´t really illformed as in your question just use a html parse to do the job — SomeJavaGuy

You can use this regex to find href value:

href="([^"]*)"

DEMO

Matcher m = Pattern.compile("href=\"([^\"]*)\"").matcher("<a hidden=\"true\" href=\"xxx\" class=\" zt-uie-session      </a>");
if (m.find())
    System.out.println(m.group(1));

Output

xxx

Try below code it is working fine

        String str = "<a hidden=\"true\" href=\"xxx\" class=\" zt-uie-session></a>";
        Matcher m = Pattern.compile(" (?:href)=\"([^\"]+)").matcher(str);

        while (m.find()) {
            String result = m.group(1);
            Log.d("HREF",": "+result); //result is "xxx" 
        }

you can use Jsoup library for easily extract html attributes

Document doc = Jsoup.parse("<a href='link' />");
Element link = doc.select("a").first();
return link.attr("href"); //xxx
