inserting <br> won't work at this one line in xsl
I'm trying to use the following code to remove the rich text formatting "/par" tag and replace it with <br/>. The code works fine for stripping the "/par" but for some reason the <BR/> is not inserted. I tried replacing the <BR/> with **** (just some plain text) and that was inserted just fine. The problem is in the "break" template at the bottom.

Any clues on why this isn't working?
I think I just had the same problem (that's the reason I'm on this page atm). Your problem lies in the code where you output the whole thing:
<xsl:value-of select="substring($par,1,$s_length)"/>
try using:
<xsl:copy-of select="substring($par,1,$s_length)"/>
"xsl:value-of" returns only text() elements within the selected tag(s), while "xsl:copy-of" returns all elements (including text()) of the selected tag(s).
This effectively means that "xsl:value-of" simply strips "<BR/>" (an xml element), but not "****" (a text() element.
change <br/> to <xhtml:br/> to tell xsl that br is not an xml element, but should actually be rendered in the result.
[edit]
That may only work if you're actually converting to to xhtml. :-o
<BR/> isn't a valid element in xsl.
you will have to define a template, then include that template in your xsl
in your template
<xsl:template name="Newline"><xsl:text>
</xsl:text></xsl:template>
in your xslt
<xsl:value-of select="substring-before($thetext,'\par')"/>
<xsl:call-template name="Newline" />
<xsl:call-template name="break">
