# however dealing with all of these different conditions is currently |
53
|
|
|
|
|
|
|
# probably premature; the schema we have only contains 'strict' (which |

=head1 DESCRIPTION |
118
|
|
|
|
|
|
|
|
119
|
|
|
|
|
|
|
Some schema allow sections of responses to be schema-free; typically |
120
|
|
|
|
|
|
|
this is used for error responses which are allowed to include the |
121
|
|
|
|
|
|
|
errant section of XML. |
122
|
|
|
|
|
|
|
|
123
|
|
|
|
|
|
|
Fortunately, PRANG is flexible enough that this is quite easy to do. |
124
|
|
|
|
|
|
|
The result of the operation is a nested set of |
125
|
|
|
|
|
|
|
PRANG::XMLSchema::Whatever objects, which have two properties |
126
|
|
|
|
|
|
|
C<contents> and C<attributes>, which store the sub-elements and |
127
|
|
|
|
|
|
|
attributes of the element at that point. There is also the attribute |
128
|
|
|
|
|
|
|
C<nodenames> which stores the node names of nodes. Once it is |
129
|
|
|
|
|
|
|
supported, there will also be an attribute indicating the XML |
130
|
|
|
|
|
|
|
namespaces of attributes and elements (currently they will not |
131
|
|
|
|
|
|
|
round-trip successfully). |
132
|
|
|
|
|
|
|
|
133
|
|
|
|
|
|
|
This API is somewhat experimental, and may be broken down into various |
134
|
|
|
|
|
|
|
versions of 'whatever' - see the source for more. |
