dyn:evaluate() is an XPath expression, so you can use it anywhere an
XPath expression is allowed, and nowhere else.

Subject: Re: [xsl] Re: EXSL's dyn:evaluate() and XALAN vs.
xsl:use-attribute-sets
Hi,
According to the XSLT 1.0 spec "The value of the use-attribute-sets
attribute is a whitespace-separated list of names of
attribute sets.
Each name is specified as a QName ..."
A QName cannot be calculated dynamically -- it must be known at
compile time.
I'm aware of that but my understanding of the dyn:evaluate
extension is, that is let's say 'on level above the xslt
processing'. While reading the spec on exslt.org the
following sentence confirmed this somehow:
...The string is always evaluated exactly as if it had been
literally included in place of the call to the dyn:evaluate function.
And if you're right, how can one determine for which params
etc. dyn:evaluate will work?
Therefore, what you're trying to achieve is impossible in this way.
Do you have an ide, how to achive it? I also tried with
chained templates and parameters but then I really stuck with
the problem with qnames.

Hi,
As I don't really like mailinglists it was kind of hard for
me do this
step but for my current problem
I can't find a proper answer elsewhere:
Suppose I have the following XML document:
...
<elemxy class="test1">Some content</elemxy>
...
And the following template snippet:
...
<xsl:template match="elemxy">
<fo:block xsl:use-attribute-sets="dyn:evaluate(@class)">
<xsl:apply-templates/>
</fo:block>
</xsl:template>
...
Obviously I have several different class attributes (like
test1 here)
and want them to be the name of an attribute-set. This because: I'm
generating the attribute-sets dynamically
and attach them to the xsl stylesheet.
My question is now: Why is the above construct NOT working?
I'm using
xalan-j_2_5_1 and my root element of the stylesheet looks like
this:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:fo="http://www.w3.org/1999/XSL/Format";
xmlns:xalan="http://xml.apache.org/xalan";
xmlns:dyn="http://exslt.org/dynamic";
extension-element-prefixes="dyn">
Xalan simply ignores the statement. When I replace the
expression with
a static name the proper attribute-set is used.
