Perhaps it is my complete inexperience with XSL/XML, or perhaps it is the fact that I cannot figure out how to phrase my problem into Google, but I am coming up with nothing in my search:

I have an xsl:value-of select that I need to manipulate.
I am trying to find "/", then go back three characters and add a line break. Here is my raw data:
Code:
DOB/20020101 DOE/20200101 HGT/300 WGT/050 EYE/BR0 HAI/BR0
SOC/123456789
OLN/123456789
Here is what I want it to look like:
Code:
DOB/20020101
DOE/20200101
HGT/300
WGT/050
EYE/BR0
HAI/BR0
SOC/123456789
OLN/123456789
I will use normalize-space to get it to take away excess line breaks, but I can't get the $xa; where i want it to go. (This is my first attempt at changing an xsl file, so I'm not sure how well I'm explaining, so sorry if this is not well explained.) Thanks in advance.
