19.1. XML Classes

19.1.1. Specification

XML classes are composed of the SOAP / XML processing for Web service, creating XML document, and parsing XML document.

The XML parser of SophiaFramework supports DTD and XMLSchema, and DOM ( Document Object Model ) and SAX ( Simple API for XML ) can be also available.

In SOAP RPC(SFXSOAPRPC), SOAP messages based on Simple Object Access Protocol (SOAP) 1.1 are sent and received via HTTP-POST.

* SOAP Messages with Attachments is NOT implemented.

[Note] About SAX ( Simple API for XML )

Information on SAX is also available at the Simple API for XML.

19.1.2. Restriction

  • As for character encoding, Shift_JIS, UTF-8, and EUC-JP are supported.
  • XML parsers need a lot of memory. In particular, much heap memory is necessary if DTD, XML Schema, or WSDL is used.
  • In the future, XML specification of the W3C ( World Wide Web Consortium ) may be changed.
