Hi all,

I'm wasting a lot of time (probably because of a brain fart) googling 
for this.

I'm using Zend_Framework to generate some html which it unfortunately 
does as one giant line.  I'm pretty sure it has an error but can't find 
the missing/extra tag without formatting the html with line feeds.

Will somebody tell me the symbol to use for a linefeed in substitutions 
  as in
	:s1,$#</tag>#</tag>linefeed#g

tia,
Mike Wright
