Frist of All Import jsoap:

compile group: 'org.jsoup', name: 'jsoup', version: '1.7.2'

Then you can Use this:

private ArrayList pullLinks(String html) {
    ArrayList links = new ArrayList();
    Elements srcs = Jsoup.parse(html).select("[src]"); //get All tags containing "src"
    for (int i = 0; i < srcs.size(); i++) {
        links.add(srcs.get(i).attr("abs:src")); // get links of selected tags
    }
    return links;
}

Please see this question for reference. Basically it says to use:
```
String imgRegex = "<img[^>]+src\\s*=\\s*['\"]([^'\"]+)['\"][^>]*>";
```

An XMLPullParser can do this pretty easily. Although, if it is a trivially small string, it may be overkill.

     XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
     XmlPullParser xpp = factory.newPullParser();

     xpp.setInput( new StringReader ( "<html>I have string like this with <br> some HTML<b>tag</b> with <img src=\"http://xyz.com/par.jpg\" align=\"left\"/> image tags in it. how can get it ?</html>" ) );
     int eventType = xpp.getEventType();
     while (eventType != XmlPullParser.END_DOCUMENT) {
      if(eventType == XmlPullParser.START_TAG && "img".equals(xpp.getName()) {
          //found an image start tag, extract the attribute 'src' from here...
      }
      eventType = xpp.next();
     }

I use jsoup. It is pretty easy to use and lightweight. Some versions were not Java 1.5 compatible but it appears they fixed the issue.
```
String html = str;
Document doc = Jsoup.parse(html);
Elements pngs = doc.select("img[src$=.png]"); // img with src ending .png
```
