Using the setVariable seems to comes out blank when used later on.
I guessing its the way Im reading it back (using {} maybe).
Example Jet is below:
<c:setVariable var="className" select="HelloClass"/>
private {$className} <c:get select="lowercaseFirst($node/@tag)" />;

Stu:
A quick fix: a minor tweak to your code:
<%-- I added spaces in select= for clarity. The essentail difference is the
single quotes around 'HelloClass' --%>
<c:setVariable var="className" select=" 'HelloClass' "/>
An explanation: Without the single quotes, the XPath engine is evaluating
the expression HelloClass, which is equivalent to
../HelloClass. With JET, . maps to the "document", so this is equivalent to
/HelloClass. Odds are that you don't have
an element HelloClass at the root of you input, so className gets set to an
empty node set. The fix makes HelloClass a string - your code should now
work.
FYI: The XPath language can represent boolean, string and numeric values as
well as 'path expressions'. You can set XPath variables to contain any of
these:
<c:setVariable var="vNum" select=" 3 + 6"/>
<c:setVariable var="vString" select=" 'a String' "/>
<c:setVariable var="vBoolean" select=" 3 + 6 = 9 "/>
