XSLT » Elements » xsl:with-param
- Syntax:
- <xsl:with-param
name="qname"
>
</xsl:param>
Or:
<xsl:with-param
name="qname"
select="expression"
/>
The xsl:with-param element is used to set the explicit value of a named parameter when using the xsl:apply-templates and the xsl:call-template elements.
The concept is that the xsl:param element is used to declare a local or global parameter by assigning a name and a default value. The xsl:with-param element is used to set the actual (explicit) value which will be used in place of the default value. The name cited by the xsl:with-param element must match a name in an xsl:param element. If there is no such match, the xsl:with-param element is simply ignored, but it is not treated as an error.
Like all XSLT elements, the xsl:with-param element must be closed (well-formed). If the select attribute is present, then this element is self-closing. If the select attribute is not present, then this element is not self-closing and the separate closing element is mandatory.

</xsl:template>
<xsl:template name="boo">
<xsl:param name="myname" select="'NotAvailable'" />
<xsl:param name="mydob" select="'Not Available'"/>
<div>
