Detailed Description

Structure of each row in a namespace table.

XML namespaces tables define XML namespace prefix-URI pairs for XML generation, parsing and validation. Each row in the table is defined by this structure. The last row in the table must be followed by a row with a NULL value to indicate the end of the table. The first four rows are reserved for the namespaces of SOAP-ENV, SOAP-ENC, xsi and xsd. One or more of these entries can be omitted by using "" in the first column for the prefix, but beware that XML generation and parsing may fail when an omitted namespace prefix or URI is still used in the XML text.

This structure defines the rows the namespace table namespaces and the namespace table parameter of soap_set_namespaces.

Example:
#include "soapH.h"
struct Namespace namespaces[] = {
{"SOAP-ENV", "http://schemas.xmlsoap.org/soap/envelope/", "http://www.w3.org/*soap-envelope", NULL},
{"SOAP-ENC", "http://schemas.xmlsoap.org/soap/encoding/", "http://www.w3.org/*soap-encoding", NULL},
{"xsi", "http://www.w3.org/2001/XMLSchema-instance", "http://www.w3.org/*XMLSchema-instance", NULL},
{"xsd", "http://www.w3.org/2001/XMLSchema", "http://www.w3.org/*XMLSchema", NULL},
{"ns", "http://tempuri.org/ns.xsd", NULL, NULL},
{NULL, NULL, NULL, NULL}
};

This example defines SOAP 1.1 namespaces (SOAP-ENV and SOAP-ENC) to be used by default, but also accepts SOAP 1.2 because of the second URI in the third column. XML schema instance namespace xsi is used with xsi:type and xsi:nil and the XML schema namespace xsd is used with XSD types such as xsd:string, which may be used in XML messages. URI patterns in the third column may contain wildcard strings * and wildcard characters -.
