Is none of the string data going to vary? If you're always looking for that exact string, use [man]strstr/man or [man]stristr/man instead ...

[Weedpacket]

Or [man]strpos[/man] or [man]stripos[/man].

Or if this is an HTML document, use the HTML-document-parsing mechanisms already available for the purpose, such as [man]DOM[/man].
