Yes (in XSLT) (well almost).

<xsl:if test="@value=preceding-sibling::*[1]/@value">

does roughly what you want. The only caveat is that the "previous node on
the same level" must be a sibling, not a cousin. If you want to test against
an n-th cousin for any value of n, use
preceding::*[count(ancestor::*)=$depth][1] where $depth is initialized to
count(ancestor::*) for the context node. And be patient while it executes.

I'm not sure what you mean by "indexing elements".
