Difference between xsl:param and xsl:variable?

Hi!
Can you please explain to me the difference between a xsl:param and a
xsl:variable? Since I can assign a value to both only once, what's the
point? A small example would help me a lot.

Regards,
Karsten.

Hi Karsten,
you can assign different values to xsl:param like in the following example

....
<xsl:call-template name="foo">
<xsl:with-param name="arg" select="1"/>
</xsl:call-template>
<xsl:call-template name="foo">
<xsl:with-param name="arg" select="2"/>
</xsl:call-template>
....
<xsl:template name="foo">
<xsl:param name="arg" />
...
</xsl:template>

Best regards, Stephan

An XSLT processor allows (or should allow) you to pass external
parameters to a transformation for the global <xsl:param> elements you
have in your stylesheet. Check the documentation of your XSLT processor.
And if you have an <xsl:param> element in a named template you can call
that template and pass a parameter in with
<xsl:call-template name="templateName">
<xsl:with-param name="paramName" select="xpathHere" />
</xsl:call-template>
much like in other programming languages you declare a function with
formal parameters and then call it with actual parameters.

A variable is just meant to store some value.

Thanks, Martin Honnen and Stephan Dahl for the clear explanation. I
can use param to set default values for the stylesheet/named template,
which may or may not be overriden. So param is more powerful than
variable, I could use param instead of variable.

Karsten.
