In XSLT 1.0, xsl:value-of when applied to a set of nodes gives you the value
of the first node, and ignores the others.
In XSLT 2.0, it gives you the values of all the nodes - by default space
separated.
If you run a 2.0 processor but specify version="1.0" you get
backwards-compatible behavior, i.e. the 2.0 processor gives you the same
result as a 1.0 processor.

Subject: [xsl] Weird XPath evaluation differences between
Saxon and Xalan
Hi,
I have a question regarding a XPath evaluation difference
between Saxon
and Xalan (using the latest release of both tools), with the same XML
datas and the XPath query !
Considering this XML tree :
<GROUP>
<SOMETHING>
<NAME>AA</NAME>
</SOMETHING>
<SOMETHING>
<NAME>BB</NAME>
</SOMETHING>
<SOMETHING>
<NAME>CC</NAME>
</SOMETHING>
</GROUP>
and the following XPath query :
<xsl:value-of select="./SOMETHING/NAME"/>
in the context of a <xsl:apply-templates select="/GROUP"/>
Xalan will output "AA" but Saxon output "AABBCC" !
Stranger is than changing the version of the stylesheet modify the
comportment of Saxon : using a 1.0 stylesheet, Saxon will output "AA"
(as Xalan do !), but using à 2.0 stylesheet, Saxon output "AABBCC".
What's the standard says about that ? I'd like to follow W3C
prescription !
Should I change my XPath query with GROUP like :
<xsl:value-of select="./SOMETHING//NAME"/>
or maybe :
<xsl:value-of select="./SOMETHING[*]/NAME"/>
Thanks forward for any information on this subject. For
information, the
result I expect is "AABBCC".
