Hi,

The following snippet will take an arbitrary text variable, split in on
newline boundaries, and generate a bulleted list.

<dtml-in "_.string.split(text, '\n')">
  <dtml-if sequence-start>
    <ul>
  </dtml-if>
  <li><dtml-var sequence-item>
  <dtml-if sequence-end>
    </ul>
  </dtml-if>
</dtml-in>

If you need to handle \n\r pairs as well, you could use string.replace to
handle the conversion. However, the above should work even with \n\r, as it
will just leave a leading \r in the text.

hth,
