Hello group,
Tempore 22:47:47, die 07/25/2005 AD, hinc in xsl-list@xxxxxxxxxxxxxxxxxxxxxx scripsit Elaine Prata <Elaine.Prata@xxxxxxxxxxxxxx>:
This problem encouraged me to finally post about some lack of functionality I've always been experiencing in XPath1.0
I'd wish I could solve the problem above with an Xpath like this:
$SetA/Element[$setB/Element[substring-after(.,'.')=context(1)]]
'context(n)' would recall the n-th context node (as found when propagating upwards in the predicates of the expression)
e.g.:
'context(0)' is equal to '.'
'context(1)' is equal to the context node as constructed by the immmediately outer predicate.
...
'context(-1)' would be equal to the context node as found in the outermost predicate.
Will this kind of functionality be available in Xpath 2 ? Or is it a proof of bad coding practices that one thinks he should be needing this?
please ask for more explanation if I did not stated this clear.
[xsl] Context node traversal inside predicates (was: Nodes and Strings)

Hello group,
Tempore 22:47:47, die 07/25/2005 AD, hinc in xsl-list@xxxxxxxxxxxxxxxxxxxxxx scripsit Elaine Prata <Elaine.Prata@xxxxxxxxxxxxxx>:
<setA> <element>value1</element> <element>value2</element> <element>value3</element> <element>value4</element> <element>value5</element> </setA>
<setB> <element>aStringBeforeValue.value1</element> <element>aStringBeforeValue.value2</element> <element>aStringBeforeValue.value3</element> </setB>
expected result (for intersection between the sets):
<setC> <element>value1</element> <element>value2</element> <element>value3</element> </setC>

$SetA/Element[$setB/Element[substring-after(.,'.')=context(1)]]
The 'context()' function would be similar to the 'current()' fuction. It would recall previous context nodes.
'context(n)' would recall the n-th context node (as found when propagating upwards in the predicates of the expression)
e.g.:
'context(0)' is equal to '.'
'context(1)' is equal to the context node as constructed by the immmediately outer predicate.

'context(-1)' would be equal to the context node as found in the outermost predicate.
