Re: [xsl] function returning string with string-join()

---

Hi,

I would have done this one simply as
...
<xsl:sequence select="string-join (('NO', if (string($input)) then string($input) else 'x', ',html'), '')"/>
...
with the feeling that string-join() is typically faster than concat() and string() faster than set operation with predicates, and that the overall instruction is easier to read and understand

Am I right?

Cheers,
ac

When returning atomics (such as xs:string) you should use xs:sequence
and not xsl:value-of, as value-of will create a text node that then
gets "atomized" to an atomic.

Thanks for that reminder... xsl:for-each-group and regular expressions are well settled in my XSLT2 mind-set, but xsl:sequence is more or less ignored.

If you didnt have the xsl:message call you could do:

<xsl:function name="my:filename" as="xs:string">
<xsl:param name="input" as="xs:integer" />
<xsl:sequence select="concat(if ($input = (1,2)) then ('NO1',
'NO2')[$input] else 'NOx', '.html')"/>
</xsl:function>

Yes, if...

I still try to find the best balance between writing some complex, possibly hard to debug multi-line XPath expressions or a tree of XSLT elements. Haven't found a general rule for that, and maybe there isn't.

Thanks a lot,

- Michael
