yes there is a issue with even this approach.
I am using XSL 1.0
1.

<xsl:decimal-format name="phonenumber" decimal-separator="-" grouping-separator="&#x2011;"/>
<xsl:template match="/">
<xsl:value-of select='format-number(1234567890 div 10000, "#&#x2011;###-####", "phonenumber")' />
</xsl:template>

2.
<xsl:decimal-format name="staff" grouping-separator="-"/>

Thanks,
Anil

thanks for your response. this is returing me xx-xxxx-xxxx format not xxx-xxx-xxxx.

what could be the issue.

That looks like a bug in your XSLT processor.

(But this is not the way I would recommend tackling this problem).
