BBEdit: Is It Possible to Gnerate Unique Identifiers in an HTML File With a Text Factory?

Question

I have an HTML file with multiple instances of “mkt_edit_me_”, and I’m trying to set up a Text Factory that will make each instance unique.

I’m trying to turn this…

<div class="mktEditable" id="mkt_edit_me_">
<div class="mktEditable" id="mkt_edit_me_">
<div class="mktEditable" id="mkt_edit_me_">

…into this:

<div class="mktEditable" id="unique_id_1">
<div class="mktEditable" id="unique_id_2">
<div class="mktEditable" id="unique_id_3">

The suffixes don’t need to be sequential, or even logical. Any random conglomeration of alphanumeric characters is fine, just as long as each instance of id="mkt_edit_me_" is replaced with something that doesn’t repeat within the HTML file.

I thought I could do this with GREP, but it appears you can only use GREP expressions in the Find field.

Is this possible through other means? Using Run Unix Command or Run AppleScript Filter perhaps?

Thank you in advance!
