Processor Question

[Leslie Hartman]

Hello:     I would like to take a file and remove all but the first 10 lines of or the first 256 bytes. Is there a way to do this with one of the existing processors?     Second question     Is there a processor that would remove say everything from unambiguously to the end of the file.     Say every file of type x that you were processing had the word unambiguously in it and you only wanted the content that came before that word and nothing following it, how would one do that. Example: Input HTML5 defines a <nav> menu, which is to be used to contain the primary navigation of a web site, be it a list of links or a form element such as a search box. This is a good idea, as previous to this we would contain the navigation block inside something like <div id="navigation">. Yes, you can identify this for styling purposes pretty well, but it is a <div>, and therefore semantically anonymous. <nav> gives us a consistent way to unambiguously define with the primary navigation is, which is good for things like search engine optimization, and for visually Example: Output HTML5 defines a <nav> menu, which is to be used to contain the primary navigation of a web site, be it a list of links or a form element such as a search box.
