Re: replace

Probably the safest way to do this is to first split out all HTML tags, then do a search and replace on the text, then reassemble it. Something like this might work: // $document contains your html page // split off html tags $htmltags = _striphtml($document); // split off non-html tags $htmlwords = _splithtml($document); // do your replacement on non-html content $htmlwords = preg_replace("a","",$htmlwords); // reassemble the document $document = _assemblehtml($htmltags,$htmlwords); function _striphtml($document) { // return all html markup and javascript blocks in an array preg_match_all("'<script[^>]*?>.*?</script>|<[\/\!]*?[^<>]*?>|\&\w+\;'si", $document, $tags); return $tags[0]; } function _splithtml($document) { // return all data around html tags and javascript blocks in an array $htmlwords = preg_split("'<script[^>]*?>.*?</script>|<[\/\!]*?[^<>]*?>|\&\w+\;'si", $document); return $htmlwords; } function _assemblehtml($tags,$body) { for($x=0; $x <= count($body); $x++) { $combinedtext .= $body[$x]; $combinedtext .= $tags[$x]; } return $combinedtext; } Mark McIntyre wrote: > Is it possible to replace all strings in a document, unless that string is > within a tag?
