This plugin allows you to cut string of valid XTHML at a specified character limit (UTF-8 and HTML-escape-code aware) and then add a trailing ellipsis. The end result is still valid XHTML.
Example:
<txp:rvm_substr length="8"><txp:body /></txp:rvm_substr>
will output “long str…”, assuming the body contains ‘long string’.
