my site (asp.net + c#) has faq data pull site's web service in xml format. data size pretty small (just 50 faqs). want implement keyword search faq , highlight search keyword. fast , easy approach this? my first thought using c# string search or xml search method. know not scalable. consider faq little, may not need index faq. wrong. can give me suggestions? thanks. the best solution using regular expressions . regex scales too, don't need worry speed. using regex replace, adding tag around matches make them stand out easy well. you can find regex tutorial here . has info both general regex use, , link goes explanation .nets implementation. regex has step learning curve, worth effort, because incredibly powerful.

string getline() { char parameter[26] = {null}; infile.getline (parameter,26,' '); return parameter; } now example of input file looks this: ~in.txt~ bac bca(space after last a) ~end file~ i have have space after or else function line won't work. there way not have space after , still work? i have 26, because input line have 26 letters in it. i need have them separated have because how use it: string in, post; in = getline(); post = getline(); thanks suggestions on this, small chunk of code program i'm still working on. wanna cover bases because professor testing program own input file , don't know if input file end space. this kind of silly redundant function, , don't know why call "getline", here ya go: string getline() { string s; infile >> s; return s; }
