Combining the use of preceding and following sibling in the same xpath query

Question

I have a quite simple problem but i can\'t seem to resolve it. Let\'s say i have the following code:

    zyx
            


        

Answer 1

You can combine the tests in the predicate using and.

Answer 2

Also, this XPath 1.0:

/a/b[preceding-sibling::b/@property='p1'][following-sibling::b/@property='p2']

Note: Don't use // as first step. Whenever you can replace and operator by predicates, do it.

In XPath 2.0:

/a/b[. >> ../b[@property='p1']][../b[@property='p2'] >> .]

Answer 3

XPath 1.0:

/a/b[preceding-sibling::b/@property='p1' and following-sibling::b/@property='p2']

XPath 2.0:
The expression above has some quirks in XSLT 2.0, it is better to use the new and safer operators << (before) and >> (after).

/a/b[../b[@property='p2'] << . and . >> ../b[@property='p1']]
