Can an XSL stylesheet have 2 root templates ?

Hi,

Can an XSL stylesheet have 2 root templates ? How about 2
templates that match the same set of nodes ? Which one gets executed ?

Hi Razvan,
There are a set of rules defined by the XSLT spec for conflict
resolution for selecting which templates to select. Please do read the
spec for detailed description.

In a normal stylesheet you cannot have two template rules having the
same match pattern. This is also valid for root node. If you have 2
root templates, the processor will usually give an error.

But you may invoke the transform with an initial mode. For e.g. Saxon
provides -im option to specify the initial mode.

So you may have 2 templates for root node as below:
<xsl:template match="/">

</xsl:template>

<xsl:template match="/" mode="x" >

</xsl:template>

These templates both match the root node, but are differentiated by
the mode.

If you invoke the transformation with -im x option, the 2nd rule will
be invoked, otherwise 1st rule will be invoked.

Mukul

Hi Mukul,

I did not know about this "mode" parameter. Indeed, it can be
useful for selecting a template directly at runtime.

Pass file name parameter to xsl stylesheet

by: Luke Airig | last post by:

I am using the Saxon 6.5.3 engine and I have an xsl stylesheet that merges two files on a date_time field and writes out a tab-delimited flat file.

This version executes but does not appear to do the merge processing and drops the longitude and...
