How to use PageSeeder's Web service API

list uri xreftree

/groups/{group}/uris/{uri}/xreftree [GET]



Loads the XRef tree for a URI

Starting from a nominated URI, this service returns a tree of fragments that contain XRefs.

  • The fragments and XRefs in the tree are in the same order as they are in the document, starting with the default fragment.
  • Only PSML document fragments accessible to the group will be in the response.

If allfragments=false and depth is larger than 1:

  • Forward XRefs to fragments (not default) will only include XRefs from that fragment.
  • Reverse XRefs will only include reverse XRefs from that fragment and default.

If duplicates=false and XRefs for a URI or fragment have already been output they may be omitted later in the tree when they are leaf nodes. When this happens the element <omitted forward="[true|false]" reverse="[true|false]" /> will be output. If forward="true" then forward XRefs may have been omitted and if reverse="true" then reverse XRefs may have been omitted. They will be omitted from that point and below in the tree.
