"The optional offset parameter allows you to specify which character in haystack to start searching. The position returned is still relative to the the beginning of haystack." So if you are trying to find subsequent occurrences of the string, you'd need to make the offset be greater than the last character you checked, or you're going to keep getting the first occurrence. > $XML_Start = (strpos($res_str,"<![CDATA[",1)+9); > $HTML_Start = (strpos($res_str,"<![CDATA[",2)+9); > $HTML_End = strpos($res_str,"]]>",1); > $XML_End = strpos($res_str,"]]>",2); If you're just trying to pull one bit of data out of a file, you might want to look into regex for this purpose. If you're actually trying to write a parser, I think you might do well to read up on how other parsers work (like, using a stack). Anyway, don't do that, use an existing XML parser.. unless you are on a learning quest.. then, by all means! -- Kelly Hallman //Ultrafancy/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
