reg expr -> Searching text but avoiding HTML code

rgraves

Hi,

I have a search page that searches through a database, stores the results into a string and then highlights the text in the string that matches the search query.

i.e.
If I search for "width", then if "The width of a cabinet" was in the database, the word "width" would be highlighted. It uses width to highlight the text.

I have the highlight feature working, the problem is that the database contains both HTML code and ordinary text to be displayed on screen. So when I search through the database to highlight certain pieces of text, it also highlights HTML code if it matches.

In the example above, it would take "<td width='150'>" and change it to "<td width='150'>"

Does anyone know how I can use regular expressions (or another option if there is one) to search through and ignore the HTML code in the string?

have you tried the strip_tags function?

The problem with using the strip_tags function is that I still want to retain the HTML code in there.

Right now I use the following to put the tags around the keyword ($word):

$data['txt'] = preg_replace("/*($word)/i","\0",$data['txt']);

I want to do this but only on the 'plain text', not any HTML code that exists in $data['txt'].

This way I can print $data['txt'] and it will print the HTML code as well as the plain text code with highlights in it.

You may need to use a second regex something like this

$string = preg_replace("#<(.+?)>#is","\1",$string);

It doesnt work great it still leave the "/" on

try

preg_replace("/(?<!\\<[^\\>]*)($word)(?![^\\<]*\\>)/i","<span class='highlight'>\\\\1</span>",$data['txt']);
