Hi,

I know this may appear easy but please can someone help.

In the example below, am I right in thinking that:

1.
The Parameter name is 'ToOrFrom'

2.
The value to be passed is 'From'

3.
The template to be called is 'DeliveryNotificationHeader'.


<xsl:call-template name="DeliveryNotificationHeader">
    <xsl:with-param name="ToOrFrom">From</xsl:with-param>
</xsl:call-template>

I have had limited experience in this field.

Many thanks,




Neal

Yes, almost. In fact the value of the parameter is a result-tree-fragment consisting of a document node that owns a text node whose value is "From". For most practical purposes this will behave exactly like passing the string "From", but it's a lot less efficient. It's better to pass the string itself:

<xsl:with-param name="ToOrFrom" select="'From'"/>

Note the nested quotes.

Excellent, very prompt.

So, are there any beneifts in the original code?

(FYI - The template is a separate XSL form)

Thanks again,

There are obviously cases where you do need to build a real result tree fragment (typically it will contain elements) but an RTF that only contains a single text node is always pointless.

Having said that, there's one case I use them which is

<xsl:variable name="quote">"</xsl:variable>

which is purely for the convenience of not having to escape the quotes.
