JT> <xsl:template match="br" mode="copy">
JT>   <xsl:copy-of select="." />
JT> </xsl:template>

JT> and a template that matches the text nodes, and passes on their

JT> <xsl:template match="text()" mode="copy">
JT>   <xsl:call-template name="text2hyper">
JT>     <xsl:with-param name="strTemp" select="." />
JT>   </xsl:call-template>
JT> </xsl:template>

JT> Alternatively you could combine the two templates. For example, rather
JT> than just doing:

JT>   <xsl:value-of select="substring-before($string, $from)" />

JT> in the NewLine2Break template, you could call the text2hyper template
JT> on that substring:

JT>   <xsl:call-template name="text2hyper">
JT>     <xsl:with-param name="strTemp"
JT>                     select="substring-before($string, $from)" />
JT>   </xsl:call-template>

JT> Whether you want to do this probably depends on whether you'll ever

Good Morning Jeni;

A  quick  thank you. I'm going to go with your suggestion of combining
the  templates  and avoid using an extension. This is provin more of a
challenge than I had anticipated though.

I'm sure I'll have more questions shortly.

Thanks,

Pete
