Hi,
A few questions:
1.
Would it not be preferable to invert the choose as in
<xsl:for-each select="( . . .)">
<xsl:choose>
<xsl:when test=". instance of xs:anyAtomicType">
<xsl:value-of select="."/>
</xsl:when>
<xsl:otherwise>
<xsl:apply-templates select="$foo,." />
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
especially since node() will also return text nodes that should probably
be atomized ?
2.
Also, wouldn't castable as be preferable to instance of, in this case ?
If so, might one want to separate strings, boolean, numbers and
integers, as in
...
<xsl:choose>
<xsl:when test=". instance of xs:integer"> ... </when>
<xsl:when test=". instance of number()"> ... </when>
<xsl:when test=". instance of xs:boolean"> ... </when>
<xsl:when test=". castable as xs:integer"> ... </when>
<xsl:when test=". castable as number()"> ... </when>
<xsl:when test=". castable as xs:boolean"> ... </when>
<xsl:when test=". castable as xs:string"> ... </when>
<xsl:otherwise><xsl:apply-templates select="$foo,." /></xsl:otherwise>
</xsl:choose>
?
3.
What would be the best way to do this ?
4.
As for the use cases, aren't there more than might seem at first, especially
where dynamic evaluation (ex: saxon:eval()) is used?
Thanks.
Cheers,
ac

David Carlisle a écrit :
a safer way is to use a global param, this prevents a static type error
(as the system can not know that you will not pass in a node) but if you
never do pass in a value then teh run time behaviour is as you wish:
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:param name="foo" select="()"/>
<xsl:template name="x">
<xsl:for-each select="(1, 2, 3)">
<xsl:choose>
<xsl:when test=". instance of node()">
<xsl:apply-templates select="$foo,." />
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="."/>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
$ saxon9 -it x stst.xsl
