Thanks Martin:

>> <xsl:value-of select="concat(substring-before(., '.'), '. ', 
substring-after(., '.'))"/>

Works fine with single initial or two initials.

<given-name>A.</given-name> or <given-name>A.H.</given-name> but fails for 
the 3 or four initials.

                    <xsl:call-template name="replace-substring">
                        <xsl:with-param name="original" select="."/>
                        <xsl:with-param name="substring" select="'.'"/>
                        <xsl:with-param name="replacement" select="'. '"/>
                    </xsl:call-template>
is somewhat near to the requirement but the only thing is that it adds 
"space" to last initial too. (A.H. to A. H. ), which I do not want.

The best I have done is 

<xsl:template match="given-name">
<xsl:copy>
    <xsl:choose>
    <xsl:when test="string-length(.)=2 and contains(.,'.')">
        <xsl:value-of select="."/>
    </xsl:when>
    <xsl:when test="string-length(.)=4 and contains(.,'.')">
        <xsl:value-of select="concat(substring-before(., '.'), '. ', 
substring-after(., '.'))"/>    </xsl:when>
    <xsl:otherwise> 
 
                    <xsl:call-template name="replace-substring">
                        <xsl:with-param name="original" select="."/>
                        <xsl:with-param name="substring" select="'.'"/>
                        <xsl:with-param name="replacement" select="'. '"/>
                    </xsl:call-template>
    </xsl:otherwise>
    </xsl:choose>
  </xsl:copy>
</xsl:template>

<xsl:template name="replace-substring">
<xsl:param name="original"/>
<xsl:param name="substring"/>
<xsl:param name="replacement" select="'. '"/>
<xsl:choose>
    <xsl:when test="contains($original, $substring)">
        <xsl:value-of select="substring-before($original, $substring)"/>
        <xsl:copy-of select="$replacement"/>
        <xsl:call-template name="replace-substring">
            <xsl:with-param name="original" 
select="substring-after($original, $substring)"/>
            <xsl:with-param name="substring" select="$substring"/>
            <xsl:with-param name="replacement" select="$replacement"/>
        </xsl:call-template>
    </xsl:when>
    <xsl:otherwise>
        <xsl:value-of select="$original"/>
    </xsl:otherwise>
</xsl:choose>
</xsl:template>

I would prefer to use replace() function if there is way of avoiding last 
intial "space". AARRRGH, time to switch to 2.0 for this project.

Looking for thoughts

TIA,
