This counts characters which would be good for a single byte character
encoding.

This transformation:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

 <xsl:output omit-xml-declaration="yes"/>

  <xsl:template match="@* | node()">
    <xsl:copy>
      <xsl:apply-templates select="@* | node()"/>
    </xsl:copy>
  </xsl:template>

 <xsl:template match="/">
   <xsl:variable name="vResult">
     <xsl:apply-templates/>
   </xsl:variable>

   Length of output is: <xsl:text/>
   <xsl:value-of select="concat(string-length($vResult), '&#xA;')"/>

   <xsl:if test="string-length($vResult) &lt;= 1800">
     <xsl:copy-of select="$vResult"/>
   </xsl:if>
 </xsl:template>

</xsl:stylesheet>


when applied on this source.xml:

<nums>
  <num>01</num>
  <num>02</num>
  <num>03</num>
  <num>04</num>
  <num>05</num>
  <num>06</num>
  <num>07</num>
  <num>08</num>
  <num>09</num>
  <num>10</num>
</nums>

produces the wanted result:

   Length of output is: 51
<nums>
  <num>01</num>
  <num>02</num>
  <num>03</num>
  <num>04</num>
  <num>05</num>
  <num>06</num>
  <num>07</num>
  <num>08</num>
  <num>09</num>
  <num>10</num>
</nums>
