Hi Abel,
Sorry for the confusion. I meant only attribute nodes so I assume from your
examples that I have to put the entire path before each attribute of
interest.
Ie // tier1 / tier2 / @attrb1 | // tier1 / tier2 / @attrb2
Is there a way to exclude specific attributes in Xpath 1.0?
Well, like I said, usually the easiest way to do that is by using an
identity transform (see my examples), but I haven't seen your code so I
can't tell it's the right approach.
With any of your XPaths, however, this works for excluding attributes:
//tier1/tier2/@*[not(local-name() = 'exclude-me')]
and this with QNames:
//tier1/tier2/@*[not(name() = 'ns:exclude-me')]
Finally, you may have hoped this would work, like it does for normal axis:
//tier1/tier2/@*[not(self::exclude-me)]
but then you try to test for the self::node() being an 'exclude-me'
element node, but self::node() is not an element, it is an attribute
(the reason is, technically speaking, that the principal node kind of
self:: is the element node, and you can't switch that). Unfortunately,
XPath does not have a way to express a self::node() axis when the axis
is the attribute axis. I.e., this won't work (illegal):
//tier1/tier2/@*[not(self::@exclude-me)]
XPath 2.0 has a workaround for this (also note the way of using
parenthesis, which is not legal for XPath 1.0, but in this case saves a
lot of re-typing the parent path):
//tier1/tier2/(@* except @exclude-me)
