No as
[not(substring-before(@href,'#')=substring-before(preceding::a/@href,'#'))]
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
this takes the string value of the node set which is the string value of
the first node, so that only tests the current href attribute with the
first href attribute in the document, not with all the preceding ones.
This is really a grouping broblem see th egrouping techniques at Jeni's
site.
Basically you want to construct a key that uses
match="a[contains(@href,'#')" use="substring-before(@href,'#')"
then using key() you can get hold of all the links with the same base.
