Your xpath needs to at least be //pbl:castmember/pbl:role[$id =
@xml:id]/personname

where $id is a variable defined before the select as:

substring-after(@href), '#')    (notice the single quotes around the
hash... or "pound" sign if you speak American)

or just use substring-after(current()/@href), '#') directly in the XPath.

Ultimately though this should be rewritten to use a key:

<xsl:key name="role-by-id" match="pbl:role" use="@xml:id"/>

and then just

<xsl:template match="pbl:roleref>
  <xsl:value-of select="key('role-by-id', substring-after(@href, '#'))"/>

If the lookup value doesn't exist in the key then nothing is returned.
