Re: [xsl] Plain Text Handling in XSLT Output

["Georg Hohmann" <georg.hohmann@xxxxxxxxx>]

Ups, thanks for all the answers! This is the the only mailinglist i
know where you get replies in a nanosecond. ;-) Now i will chum up

statements with the method mentioned by andrew. I think this will make
my scripts much smaller.
