RE: [xsl] Getting the data type of an element

[David.Pawson@xxxxxxxxxxx]

MK said:
 but in XSLT 2.0 you do this with
    
    test="data(.) instance of xs:boolean"

http://www.w3.org/TR/xquery-operators/#func-data
says,
  
Summary: fn:data takes a sequence of items and returns a sequence of atomic
values.

The result of fn:data is the sequence of atomic values produced by applying
the following rules to each item in $arg:

If the item is an atomic value, it is returned.

If the item is a node, fn:data() returns the typed value of the node as
defined by the accessor function dm:typed-value in Section 5.6 typed-value
AccessorDM.



How can a sequence of anything be an instance of xs:boolean Mike?


<xsl:if test=". instance of xs:boolean">

I'd interpret that as 'the context node value is a boolean'.
What's the difference between . and data(.) please?

Are  you are assuming the context is a sequence of one item?
