=head1 DESCRIPTION |
17
|
|
|
|
|
|
|
|
18
|
|
|
|
|
|
|
It will forward any element belonging to a namespace from this list |
19
|
|
|
|
|
|
|
to the associated SAX filter and all of the element's children |
20
|
|
|
|
|
|
|
(regardless of their respective namespace) to the same one. It can be used either as a |
21
|
|
|
|
|
|
|
C or C. |
22
|
|
|
|
|
|
|
|
23
|
|
|
|
|
|
|
This SAX filter takes a hashref C as argument, with namespace |
24
|
|
|
|
|
|
|
URIs for keys ('*' for "any") and either |
25
|
|
|
|
|
|
|
|
26
|
|
|
|
|
|
|
over 4 |
27
|
|
|
|
|
|
|
|
28
|
|
|
|
|
|
|
=item undef |
29
|
|
|
|
|
|
|
|
30
|
|
|
|
|
|
|
Matching elements and their subelements are suppressed. |
31
|
|
|
|
|
|
|
|
32
|
|
|
|
|
|
|
If the list of namespaces ist empty or C is connected to |
33
|
|
|
|
|
|
|
the filter, it effectively acts as a plug to Net::OAI::Harvester. This |
34
|
|
|
|
|
|
|
might come handy if you are planning to get to the raw result by other |
35
|
|
|
|
|
|
|
means, e.g. by tapping the user agent or accessing the result's xml() method: |
36
|
|
|
|
|
|
|
|
37
|
|
|
|
|
|
|
$plug = Net::OAI::Harvester::Record::NamespaceFilter(); |

For any record element of the OAI response a new instance |

is created. |
