how to get src/url from <iframe> using java

Question

 String str = " <iframe width=\"640\" height=\"360\" src=\"https://www.youtube.com/embed/UMUeWqnwmjs\" frameborder=\"0\" allowfullscreen></iframe>";

How to take the Src from this tag?

Answer 1

In such simple case you can use regexp (normally you should not use it for parsing html). The code below will look for src and retrieve it:

Matcher matcher = Pattern.compile("src=\"([^\"]+)\"").matcher(str);
matcher.find();
String src = matcher.group(1);

src will contain your src from iframe.
