[xsl] Grouping / unique list with just XPath

[Alexander Johannesen <alexander.johannesen@xxxxxxxxx>]

Hi,

Tearing my non-exsistant hair out over this one. I basically have

  <member refid="nla.int-ex7-s8" role="role-item" />
  <member refid="nla.int-ex7-s8" role="role-item" />
  <member refid="nla.int-ex7-s8" role="role-item" />
  <member refid="nla.int-ex8-s39" role="role-item" />
  <member refid="nla.int-ex8-s14" role="role-item" />
  <member refid="nla.int-ex8-s14" role="role-item" />
  <member refid="nla.int-ex8-s14" role="role-item" />

in a $variable, and need the unique list of nodes

  <member refid="nla.int-ex7-s8" role="role-item" />
  <member refid="nla.int-ex8-s39" role="role-item" />
  <member refid="nla.int-ex8-s14" role="role-item" />

in $variable-two. This is a dynamic XML input, and hence I can't use
keys (bye, Muenchian), and I need it as a node-tree that will be
passed to a named template for processing. Any clues? At all possible?


Kind regards,

Alex
