[Templates] highlight search terms google-cache-style

[Vincent D Murphy]

i would like to highlight search terms in a html page of search results, by passing an array of scalars which are the search terms.

this is my code without highlighting. the string i want to add the highlighting markup to is c.postaladdress . i would need to supply two arguments: an array 'terms', and the markup to use, e.g. "<span class="term"></span>".

[% FOREACH c = results %]<tr class="[% next_rowclass() %]"><td class="numCol"><a href="[% c.id %]">[% c.id %]</a></td><td>[% c.postaladdress FILTER html %]</td></tr>
[% END %]</table>

perhaps i could have something like this:

[% c.postaladdress FILTER html FILTER highlight(terms, "<span class='term'>", "</span>") %]

is there any obvious/idiomatic way to do this in TT? i don't really know whether to write a filter or just some plain perl code that matches the terms against the output and spits out a scalar which i can use in the template instead of c.postaladdress.

could somebody with TT experience advise whether this is a good idea? i'm not really looking for a complete answer as much as a point in the right direction.

TIA,
-vincent
