Pattern or regex in Java to delete the hyperlinks in the text descritpion

I have a text about a product description . I want to delete the hyperlinks but i want to keep the <img links . 1- I was able to delete the hyperlinks from the text by using this Java function private String removeUrl(String commentstr) { String urlPattern = "((https?|ftp|gopher|telnet|file|Unsure):((//)|(\\\\))+[\\w\\d:#@%/;$()~_?\\+-=\\\\\\.&]*)"; Pattern p = [login to view URL](urlPattern,Pattern.CASE_INSENSITIVE); Matcher m = [login to view URL](commentstr); StringBuffer sb = new StringBuffer([login to view URL]()); while ([login to view URL]()) { [login to view URL](sb, ""); } return [login to view URL](); } 2- I need it to exclude hyperlinks that are images , So something you can write to exclude delete links that ends with png, jpg or such . you choose the way you want
