Description
Converts an XML entity to an SQL value based on the type of the entity and the desired SQL type. This function is called internally to convert a SOAP request parameter to a PL procedure parameter when a SOAP request is being processed by the SOAP server.
Parameters
entity
The XML fragment as a vector (as returned from
xml_tree()
or a subpart of it).
try_typed_as
A sample value, whose type is taken as a desired type for conversion.
soap_version
Optional (default 1). The soap version (1 for SOAP 1.0, 11 for SOAP 1.1).
Return Types
The return type of
soap_box_xml_entity()
can
vary according to the type of entity
parameter, described
by try_typed_as
as follows:
If entity
is NULL, the return value will be NULL. |
If entity
is not a vector() then its
value will be cast to the try_typed_as
type, if possible. |
If entity
is a vector() containing XML
tree then it will be converted to an appropriate SQL type (vector(),
varchar, integer etc.) depending on the SOAP RPC encoding rules
(XMLSchema-datatypes and SOAP-RPC encoding schema) for in/out SOAP messages.
i.e. it depends on the
structure/content of the XML tree passed as the
entity
argument. |
