Thanks David.

I think I see what you are saying, but I am having a
little bit of trouble seeing how to implement it.

I am not storing all of my output in a variable called
content.

<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:output method="text" encoding="iso-8859-1"
media-type="text/plain" indent="no" />
<xsl:strip-space elements="*" />

<xsl:template match="/">
<xsl:variable name="content">
<!--contact info -->
<xsl:value-of
select="PressRelease/MetaData/InstitutionalPAO/FName"
/><xsl:text> </xsl:text><xsl:value-of
select="PressRelease/MetaData/InstitutionalPAO/LName"
/>
<xsl:text>&#xA;</xsl:text>
<xsl:value-of
select="PressRelease/MetaData/InstitutionalPAO/JobTitle"
/>
<xsl:value-of
select="PressRelease/MetaData/InstitutionalPAO/OrgName"
/>
<xsl:value-of
select="PressRelease/MetaData/InstitutionalPAO/Address"
/>
<xsl:value-of
select="PressRelease/MetaData/InstitutionalPAO/SubAddress"
/>
Phone: <xsl:value-of
select="PressRelease/MetaData/InstitutionalPAO/Phone"
/>
Fax: <xsl:value-of
select="PressRelease/MetaData/InstitutionalPAO/Fax" />
Email: <xsl:value-of
select="PressRelease/MetaData/InstitutionalPAO/Email"
/>
<xsl:text>&#xA;</xsl:text>
RELEASE: <xsl:value-of
select="PressRelease/@ReleaseNum"
/><xsl:text>&#xA;&#xA;</xsl:text>
<xsl:value-of select="PressRelease/MetaData/Headline"
/><xsl:text>&#xA;</xsl:text>
<!-- content -->
<xsl:apply-templates select="PressRelease/Body" />
<!-- end content -->
<!-- related links -->
<xsl:text>&#xA;</xsl:text>
<xsl:text>-----------------------------RELATED
LINKS-----------------------------</xsl:text>
<xsl:apply-templates
select="PressRelease/RelatedLinks" />
<xsl:text>-----------------------------------------------------------------------</xsl:text>
<!-- end related links -->
<!-- footer -->
<xsl:text>&#xA;&#xA;</xsl:text><xsl:text>             
                   </xsl:text>-end-
</xsl:variable>
<xsl:value-of select="$content" />
</xsl:template>

But, I am not sure exactly how to send that variable
into another named recursive template and spit out
lines no greater than 72 characters long.

Could you perhaps help get me started here? I would
appreciate it.
