Trouble Counting Subseq of a String Common Lisp -

-

i trying use function count tell me how many occurrences of "<script>" tag there can't seem working. code:

(count "<script>" "<p>hello world</p><script>javascript goes here</script>" :key #'string :test #'equal)

i can't seem find examples of did find 1 remove , figured similar. how can return 1 not 0?

count counts single elements match (so use count #\a characters example, not substrings). counting substrings you'll want this:

(defun count-substrings (substring string)   (loop     sub-length = (length substring)     0 (- (length string) sub-length)     when (string= string substring                   :start1 :end1 (+ sub-length))     count it))

of course counting html tags pretty error prone. you'll want use actual parser.
