My XML file is below
[snip]
I want to write **a XPATH expression which will select
the nearest preceding sibling , which contains a
particular element ( <a> in this example) ** . I do
not want preceding sibling which do not contain the
<a> tag (also the tag <a> should be nearest to the
context node)
for e.g. if the context node is node 5 , the XPATH
expression which will select node 3(because it
contains element <a>) or for e.g. if the context node
is node 2 , the XPATH expression will select node
1(because it contains element <a>)
OK - the node set of all the preceding siblings which
fit the criterium is given by
preceding-sibling::tag[a]
The nearest preceding sibling fitting the criterium is
the last one in that nodeset (the nodes are always in
document order)... that is,
preceding-sibling::tag[a and last()]
Hope this works,
Cheers,
Dave.
