<script language="JavaScript" type="text/javascript">
document.write('&lt;a href="http://abcdefr.com/c/d/odmfndfdin000008ave/direct;wi.120;hi.600/01/" target="_blank"&gt;&lt;img src="http://ssdfcreo.com/fed/up/asdasd58s5480000008ave/direct;wi.120;hi.600/01/"/&gt;&lt;/a&gt;');

Post your best attempt so we can help you out.

You can use a pointer to step along each character in the string, and then compare what the pointer is pointing at with ' " '.

well, read a single line from the file search for rright place to replace using str or strstr(these fucntion used to find the place to insert) and then insert the replace string
