As posted before following problem

for node text I am using following template to incert <br/> tag
<xsl:template name="textwrapbb">
	<xsl:param name="Text"/>
<xsl:value-of select="substring(Text, 1, 30)"/>
<br></br>
  <xsl:variable name="rest" select="substring($Text, 31)" />
  <xsl:if test="string-length($rest) &gt; 30">
    <xsl:call-template name="textwrap">
      <xsl:with-param name="Text" select="$rest" />
    </xsl:call-template>
  </xsl:if>
 </xsl:template>
</xsl:stylesheet>

My Env. is saxon and java
and it gives following error

java.lang.StackOverflowError
t com.icl.saxon.ContentImpl.appendValue(ContentImpl.java:57)
t com.icl.saxon.ParentNodeImpl.getValue(ParentNodeImpl.java:83)
t com.icl.saxon.expr.NodeSetIntent.asString(NodeSetIntent.java:57)
t com.icl.saxon.functions.Substring.eval(Substring.java:29)
can any one tell me how to use recursive template with saxon parser

or how to do word wrap template .
 And you repplied that saxon 3.2 dosent support tail recursion.
So please can you tell me how to check in a string any word larger then 20 letter and if it exist break it in 20 letter peaces without using tail recursion.oterwise my template is becoming large as my string is larger then 300 letters.
Thanks'
