样例：
Enter your regex: [0-9]+
Enter input string to search: fdsdffd9090fd
I found the text "9090" starting at index 7 and ending at index 11.
Enter your regex: class="fav-num[^"]*"[^>]*>[^<]*
Enter input string to search: <i class="litb-icon-fav-on"></i><i class="litb-icon-fav-off"></i><span class="fav-num">(151)</span>
I found the text "class="fav-num">(151)" starting at index 71 and ending at index 92.
