XML

Enables you to project objects as XML documents, and read and write those documents. Caché XML support also lets you work with arbitrary XML documents, perform XSLT transformations, evaluate XPath expressions, and so on.

Caché support for XML includes the following elements:

The Caché SAX Parser, which validates and parses inbound and outbound XML documents (SAX means “Simple API for XML”). This parser is a built-in parser using the standard Xerces library. Caché SAX communicates with a Caché process using a high-performance, in-process call-in mechanism. You can fine-tune the parser or provide your own custom SAX interface classes.
The %XML.Adaptor class, which enables you to represent instances of that class as XML documents.
Other specialized classes in the %XML and %xsd packages.
Caché support for X.509 certificates (which you can use for encryption and digital signatures)
