Re: Limit Local Search to Content

Hi Ashley. That's what I'm doing, but want to limit what gets stored to just the content. Every page has a drop-down menu of, for instance, various cities, so I want to exclude that part of the page in my search terms. I don't want every page to think it has content on Calgary, Hamburg, Phoenix, etc. I finally walked myself through the code I had been modifying, and found that they were parsing it line by line with an fgets (rather than word by word). So was able to use Stuart's original idea of surrounding the content with an unique comment line, and setting a flag to tell whether to parse the line or not. If it found the <!-- start_search --> line, it would start parsing, and stop again when it reached the <!-- stop_search --> line. Is also nice that I can then specify multiple sections within the page if I need to. On 26-Mar-09, at 6:22 PM, Ashley Sheridan wrote:

What about storing all of the page content in the database to start with, then searching with a mysql statement is a breeze! On Thu, 2009-03-26 at 16:29 -0600, George Langley wrote:

You can't have any extra info in a closing HTML tag. This problem is usually handled using comments. Something like the following... <div id="divContent"> <!-- content begin --> sofihsod hiosdh sdh gus us u sg <!-- content end --> </div> You then just start with you see the begin comment and stop

when you

hit the end comment.

Hmm, they are stripping out the tags before looking at the words, so didn't work quite as I originally thought. The solution seems to be to explode the string based on the entire comment before doing the word-by-word storing. I wrote up the following test code that seems to work and handles any string or error I could think of. Am wondering if this is good or is there better/more efficient code? <?php function contentString($pString, $pStart, $pStop){ echo "$pString<br />"; $finalArray = array(); $finalString = ""; $exploded1 = explode($pStart, $pString); // makes array $exploded1 for ($i=1; $i<count($exploded1); $i++) // ignore first item (0) in array { $exploded2 = explode($pStop, $exploded1[$i]); array_push($finalArray, $exploded2[0]); // array of just the wanted sections } foreach ($finalArray as $value3) { $finalString .= $value3 . " "; // " " ensures separation between substrings } $finalString = trim($finalString); // trim any extra white space from beginning/end echo $finalString; echo "<br /><br />"; } // TEST $startTerm = "START"; $stopTerm = "STOP"; // test typical string $theString = "one two START three four STOP five six START seven eight STOP nine ten"; contentString($theString, $startTerm, $stopTerm); // outputs "three four seven eight" // test string with immediate START $theString = "START one two STOP three four START five six STOP seven eight START nine ten"; contentString($theString, $startTerm, $stopTerm); // outputs "one two five six nine ten" // test string with "error" (2 STARTS) $theString = "START one two START three four STOP five six START seven eight STOP nine ten"; contentString($theString, $startTerm, $stopTerm); // outputs "one two three four seven eight" // test string with no space between separators and real content $theString = "STARTone twoSTOP three four STARTfive sixSTOP seven eight STARTnine ten"; contentString($theString, $startTerm, $stopTerm); // outputs "one two five six nine ten" ?> Any thoughts/suggestions? Thanks! George
