[OPEN-ILS-GENERAL] URL Display in PAC

[Mike Rylander]

Kathy,

I was referring specifically to Located URIs, but you're absolutely correct
for unadorned 856 tags.  Here's the relevant code in the stored procedure
that pulls out Located URIs:

    uris := oils_xpath('//*[@tag="856" and (@ind1="4" or @ind1="1") and
(@ind2="0" or @ind2="1")]',marcxml);
    uri_href    := (oils_xpath('//*[@code="u"]/text()',uri_xml))[1];
    uri_label   :=
(oils_xpath('//*[@code="y"]/text()|//*[@code="3"]/text()',uri_xml))[1];
    uri_use     :=
(oils_xpath('//*[@code="z"]/text()|//*[@code="2"]/text()|//*[@code="n"]/text()',uri_xml))[1];

Thanks for poking to get clarification!

Related, you can adjust the xpath for unadorned 856 tags to pull just the
first of y, z, or 3 by appending [1] to the end, like this:

    label = node.findnodes('./*[@code="y"][1]');
    notes = node.findnodes('./*[@code="z" or @code="3"][1]');
